Executive Bifocal Lens: The Ultimate 2025 Sourcing Guide

Introduction: Navigating the Global Market for Executive Bifocal Lenses

As presbyopia prevalence rises and multi-device workflows become the norm, professionals in the USA and Europe need eyewear that adapts instantly between distance, intermediate, and near tasks. Executive bifocals—full-lens designs that replace the small “window” with seamless, continuous focus—offer that functional edge for executive and knowledge workers.

The challenge for buyers is not a lack of options, but a lack of consistent quality and reliable compliance. Suppliers vary in base curves, coating durability, add power stability, and labeling standards, making it hard to forecast performance and regulatory fit across regions.

This guide moves beyond product basics to operational essentials. You’ll learn how to specify executive bifocals by material, index, Abbe, add power, segment geometry, and coating stack; how to map supply chain choices between US/EU distribution models; and how to validate QC from sampling to incoming inspection. We detail compliance (US/UK labeling, EU MDR/medical claims, CE/PPE categories), logistics considerations (packaging, lead times, MOQs), and total cost drivers so you can position offerings to meet regional margin expectations.

Use this guide to:
– Define your lens specification and minimum performance thresholds
– Choose vendors by capability, QA depth, and regional fit
– Price for segment positioning in each market
– De-risk QC/returns and scale operations reliably

Executive bifocals should be effortless for end users—and frictionless for your business.

3 Common User Pain Points for ‘executive bifocal lens’ & Their Solutions

3 Common User Pain Points for Executive Bifocal Lenses & Their Solutions

Pain Point 1: Constant head tilting and fatigue when switching between distance, computer, and reading

• Root cause: Presbyopic users perform many quick transitions (e.g., documents to screen to face-to-face), which standard bifocals and progressive lenses can’t serve without abrupt head movement.
• Impact: Eye/neck fatigue and lost productivity as users juggle tasks more frequently.
• Executive bifocal advantage: A clear, flat-top “executive” style segment spans the full width of the lens, allowing upright posture and a consistent reading field at the top or bottom, depending on the pairing.

Solution

• Use the right executive pairing by task:
• Distance + Reading: Best for mixed office + field duties (whiteboards to reports).
• Intermediate + Reading (Computer): Best for screen-heavy roles (2–3 ft working distance).
• Pair with AR coatings and appropriate lighting to minimize glare (prevents micro-movements that increase fatigue).
• Ensure proper segment placement (reading line near the bottom of frames; segment height aligned to eye’s primary downward gaze) to reduce head tilting.
• For higher adds, keep frame sizes moderate and fit to optical center standards to minimize distortion.

Business benefit: Faster task switching with less discomfort; measurable reduction in productivity dips tied to eyewear fatigue.

---

Pain Point 2: Glare and reflections on large executive lenses; discomfort with screen use

• Root cause: The full-width reading segment exposes a larger vertical lens area, increasing reflections; many roles are screen-intensive with harsh lighting.
• Impact: Reduced clarity, increased squinting, and after-hours fatigue.

Solution

• Use high-quality anti-reflective coatings:
• Standard AR: Good for indoor use.
• Super AR: Recommended for screen-heavy roles; higher light transmission and advanced smudge/ink resistance.
• For high-usage, pair with photochromic lenses (e.g., Transitions Signature VII GEN 8) for UV-dependent tinting; ensure proper lighting and screen setups to avoid residual blue-light discomfort.
• Optimize fit and edge finish:
• Minimize lens roll-off and edge thickness with proper frame sizing and beveling.
• Consider high-index lenses (1.61/1.67) for thinner edges and reduced reflections on high-minus prescriptions.
• Educate users on glare hygiene: avoid overhead reflective surfaces, angle monitors to reduce reflections, and use workstation lighting with diffusers.

Business benefit: Lower after-hours strain and improved visual comfort, especially in modern offices with extensive screen work.

---

Pain Point 3: Weight, thickness, and aesthetic concerns, especially for high-minus or high-add prescriptions

• Root cause: Executive lenses cover a larger lens area; minus prescriptions show edge thickness, plus prescriptions show center thickness; CR39 can be heavier than high-index materials.
• Impact: Slipping frames, facial marks, and reluctance to wear the eyewear.

Solution

• Choose the right material by prescription:
• CR39 (1.50): Best for low myopia or hyperopia; lightest cost.
• 1.61 Polycarbonate or 1.61 MR-8: Stronger and thinner; good for mid-power users; standard impact resistance for polycarbonate (US market).
• 1.67 or 1.74 (MR-7/MR-174): Best for high-minus/high-plus; significantly thinner and lighter.
• Control edge thickness:
• Use smaller or medium frame sizes for high-minus prescriptions; avoid oversized lenses.
• Consider optional “thin-center” lens optimization on plus prescriptions to reduce center thickness and weight.
• Finish details:
• Edge polish and bevel shaping for comfort.
• Avoid long pantoscopic tilt or excessive vertex distance on higher adds to reduce front weight leverage.
• Use lighter frame materials (titanium, TR-90) for comfort.

Business benefit: Better wear compliance and user satisfaction; fewer fit/return issues related to thickness or comfort.

Implementation guidance for procurement/eyewear managers

• Standardize executive pairings by role profile:
• Executive Distance + Reading for client-facing staff and field operations.
• Executive Intermediate + Reading for screen-dominant teams (CAD, data, development).
• Adopt a “coating-first” policy on executive lenses to manage glare on larger surfaces.
• Set prescription material guidelines to avoid unnecessary thickness and returns:
• < +/- 2.50D: CR39 acceptable.
• +/- 2.50–5.00D: 1.61 polycarbonate or MR-8.

• +/- 5.00D: 1.67/1.74 for thinner edges and lighter weight.

• Configure fit standards: correct segment height by frame geometry, control frame sizes for high-minus prescriptions, and maintain proper vertex distance to reduce front weight in higher adds.
• Offer super AR on executive options; bundle photochromic lenses where indoor/outdoor transitions occur.

This approach addresses the three most common executive bifocal challenges—task-switching fatigue, glare on large lens areas, and thickness/weight—with clear, B2B-ready solutions that align with US and EU market practices.

Strategic Material Selection Guide for executive bifocal lens

Strategic Material Selection Guide for Executive Bifocal Lenses

Executive bifocals differ from conventional bifocals by placing the add segment across the entire near lower portion of the lens, not in a small “window.” This geometry increases the absolute near zone size and can affect edge thickness, weight, and cosmetic appearance. Material choice should therefore balance optical performance, prescription, frame type, environmental exposure, and compliance requirements.

Key trade-offs:
– Optical clarity (Abbe number) vs. index (thickness/weight)
– Impact resistance vs. surface hardness and scratch resistance
– Durability vs. cost and ease of fabrication
– Tint compatibility vs. UV and heat exposure
– Edge cosmetics vs. frame compatibility

CR‑39 plastic is a widely used baseline for executive bifocals due to good optical quality and cost efficiency, but higher-index plastics and alternative materials often provide better comfort and cosmetics for stronger prescriptions or demanding environments.

Decision framework for material selection

1. Prescription and add power
2. Low power: CR‑39 often optimal for optical quality and cost.
3. High minus (−5.00 D or stronger): consider 1.67 or 1.74 to reduce edge thickness and weight.

4. High plus (+5.00 D or stronger): index selection mainly impacts center thickness and weight; CR‑39 is usually adequate, though 1.6 can help in premium frames with strict thickness targets.

5. Frame and mounting

6. Rimless/drill-mount: prioritize materials with high impact resistance and good drilling yield (e.g., polycarbonate or Trivex).
7. Semi-rimless/nylon cord: Trivex provides a strong balance of optics and drill integrity.

8. Full-rim: broader material latitude; choose based on prescription and cosmetics.

9. Use environment and duty cycle

10. Outdoor/industrial: impact-resistant options (polycarbonate, Trivex) preferred; add hard-coat.
11. High UV/heat (e.g., vehicles, outdoor delivery): avoid easily crazed materials; confirm tint compatibility and heat stability with suppliers.

12. Cleanroom/chemical exposure: select materials and coatings rated for harsh chemicals; consult coating datasheets.

13. Coatings and tinting

14. Anti-reflective (AR) is recommended for most executives to reduce eye strain and glare.
15. Hardcoat improves scratch resistance; essential for polycarbonate, Trivex, and glass (unless specified by the supplier).

16. Tint: high-index plastics can have limitations depending on dye chemistry and heat tolerance; confirm dye compatibility before specifying.

17. Compliance and regulation

18. USA: ANSI Z80.1 spectacle standards; consider OSHA job safety standards for impact-rated needs (e.g., safety programs).
19. Europe: CE marking and EN ISO 12312‑1. Impact ratings depend on product classification; consult the supplier.

20. For specific industries (e.g., construction, manufacturing), engage EHS to validate lens material and marking requirements.

21. Add geometry and cosmetic finish

22. Executive (full-width) adds increase near zone area. For thin-rimmed or rimless frames, select higher index to maintain acceptable edge thickness and aesthetic.

Material analysis

CR‑39 plastic (1.50)
– Optical quality: High Abbe value; minimal chromatic aberration in practice.
– Weight/density: Heavier than most high-index plastics for the same power.
– Impact/chemical: Adequate but inferior to polycarbonate and Trivex for impact; surface hardness is good but not best-in-class; dye compatibility is typically straightforward.
– Cost: Lower relative to higher-index options; cost-effective for most prescriptions in full-rim frames.

Trivex (1.53)
– Optical quality: High Abbe similar to CR‑39; low chromatic aberration; optics comparable or better than polycarbonate.
– Weight/density: Lightweight and often preferred for comfort.
– Impact/chemical: Superior impact resistance; suitable for rimless/semi-rimless mounting; excellent drilling yield; improved scratch resistance vs. polycarbonate when hard-coated.
– Cost: Mid-range; premium positioning but competitive value when comfort and durability are priorities.

Polycarbonate (1.59)
– Optical quality: Lower Abbe; can show slight color fringing in strong prescriptions; acceptable for moderate powers.
– Weight/density: Lightest option; reduced mass improves comfort.
– Impact/chemical: High impact resistance; recommended for safety-centric programs; requires hardcoat for surface durability; dye compatibility varies by supplier.
– Cost: Lower to mid-range; compelling for cost-sensitive programs and protective eyewear.

Mid-index 1.60
– Optical quality: Lower Abbe than CR‑39/Trivex; adequate for most uses; slight reduction vs. 1.50.
– Weight/density: Thinner and lighter than 1.50; better cosmetics for medium-strong prescriptions.
– Impact/chemical: Moderate impact resistance; dyeing and AR performance are material/vendor dependent.
– Cost: Mid-range; strong value when thickness reduction matters and high Abbe is not critical.

High-index 1.67
– Optical quality: Low Abbe; potential for noticeable color fringing at strong prescriptions.
– Weight/density: Thinner and lighter than 1.50; significant cosmetic benefit for higher powers.
– Impact/chemical: Best used for high-prescription comfort and looks; dye compatibility and AR performance vary by supplier; confirm with lab.
– Cost: Higher; premium positioning; specify when prescription demands thickness reduction.

High-index 1.74
– Optical quality: Lowest Abbe; use careful Rx selection to mitigate aberration.
– Weight/density: Thinnest option; maximum thickness and weight reduction for high minus powers.
– Impact/chemical: High-index plastic; dye/AR properties vary; often recommended for top-end prescriptions in executive bifocals.
– Cost: Highest; reserve for high-power cases where cosmetics and comfort are critical.

Glass (1.52/1.60/1.70/1.80/1.90)
– Optical quality: Highest clarity (very high Abbe); low color fringing.
– Weight/density: Heavier than plastics; not preferred for plus powers or extended wear unless specific to application.
– Impact/chemical: Glass is fragile; not impact-rated; suited for specialty uses (e.g., certain chemical/scratch-prone environments) and as per EHS policy.
– Cost: Variable; surface hardness is excellent; AR durability depends on coatings and substrate.

Recommendations by scenario

• Low-power, full-rim office executives: CR‑39 + AR + hardcoat; consider tint for outdoor transitions.
• Medium/high minus prescriptions with executive adds: 1.67 for cosmesis and comfort; 1.74 where thickness targets are tight and Abbe is acceptable.
• Rimless/semi-rimless: Trivex for optics and durability; polycarbonate where cost is primary and optics are acceptable.
• Industrial/outdoor programs: Trivex or polycarbonate with hardcoat; verify impact compliance with supplier.
• High UV/heat exposure: Confirm heat distortion and dye compatibility for high-index; avoid materials prone to crazing.

Technical notes for buyers and lab partners

• Executive add design: Full-width segment increases near area; expect greater lens real estate for tinting/AR and potentially thicker edges at the junction in minus lenses; plan index selection accordingly.
• AR compatibility: Confirm AR stack and hardcoat compatibility by material; some high-index plastics and polycarbonate require vendor-specific AR to avoid adhesion or thermal issues.
• Edge polish and drilling: High Abbe materials tolerate standard processes well; polycarbonate/Trivex benefit from sharp drills and controlled feed to prevent cracking; avoid excessive heat during polishing for high-index plastics.
• Tint temperature limits: Verify dye max temperatures for high-index plastics to prevent warping; adjust finishing parameters accordingly.
• Quality control: Verify center thickness, edge thickness, prism balance, and add uniformity; document QA outcomes for compliance.

Quick checklist before specifying

• Prescription sphere/cylinder and add power
• Frame type and mounting method
• Required impact compliance
• Coatings and tints
• Environmental exposure and duty cycle
• Comfort targets (weight/thickness)
• Regulatory scope (USA/Europe) and internal EHS alignment

Total Landed Cost (TLC) Structure

Use the TLC model to structure supplier quotes and your pricing strategy:

Cost Component	What It Includes	Typical Range / Notes
Materials	Uncut executive bifocal blanks (CR39/PC/Trivex), add‑ons (tints, transitions), optional high‑index (1.60, 1.67)	Pricing is quote‑based and sensitive to base curve and brand; high‑index significantly increases cost.
Coatings	Scratch‑resistant hard coat, anti‑reflective (AR), premium AR (hydrophobic, oleophobic, easy‑clean), blue‑light filters	Tiered price uplift; premium AR and blue‑light are common adds.
Labor	Surfacing, edging, beveling, drilling (if needed), insert into frame, QC, packaging	Quote‑based; varies by region, tooling, and volume.
Logistics	Domestic pickup/line‑haul, customs clearance, duties/taxes, last‑mile	DDP (Delivered Duty Paid) vs. EXW; USA/EU duties differ by HS code.
Other	Return allowance, warranty claims, quality defect provisions	Reserve typically 0.5–2.0% of COGS depending on policy and historical rates.

Material Cost Drivers

Driver	Impact on Cost	Practical Insight
Material	High‑index 1.60/1.67 > Trivex > Polycarbonate > CR39	For executive bifocals, CR39 is cost‑efficient and fits most prescriptions; consider Trivex for enhanced impact resistance.
Executive Blank Design	Blank engineering for full‑field bifocal configuration	Premium blanks may have higher unit cost but enable the “no-line” executive experience that supports pricing power.
Add‑Ons	Tinting, photochromic, blue‑light	Add one to two tiers of price uplift per add‑on; photochromic and premium AR are common “premium” moves.
Coating Tier	SR (baseline), AR, Super AR	AR is often 1.5–3.0x SR price; Super AR adds further premium. Exact multiples require supplier quotes.

Labor and Process Cost Drivers

Process Step	Cost Driver	Volume Sensitivity	Notes
Blank Surfacing	Prescription complexity, QC time	Gains at ≥1,000 pairs	Complexity (spherical/cylinder/ADD) and tolerances affect time.
Edge & Bevel	Edge shape, bevel profile	Minimal economies at low volume	Ensure tooling for preferred bevel profile.
Drilled Frames	Hole count, location	Low economies at low volume	Use standard drilling templates to avoid premium setup time.
AR Deposition	Batch vs. single‑lens	Scales with batch size	Batch ovens reduce per‑lens cost at mid/high volumes.
Assembly & QA	Final inspection, packaging	Improves with SOPs	SOPs reduce rework and returns.

Logistics and Trade Terms

Aspect	USA	Europe	Notes
Shipping Mode	Air or ocean; domestic ground for distribution	Air or ocean; intra‑EU road freight	Speed vs. cost trade‑offs; air preferred for rush batches.
Incoterms	EXW, FOB, DDP commonly used	EXW, FOB, DDP, CPT, DAP	Prefer DDP for predictability; ensure HS codes align with duties/taxes.
Duties/Taxes	Duty varies by HS code; import VAT not typical	VAT on imports; duty varies by HS code	Validate HS codes early to avoid rework.
Customs Broker	Optional (simplified entries)	Often required in some countries	Broker fees predictable; avoid cost surprises.
Returns/Warranty	Reserve for defects/remakes	Same	Build a policy that preserves margin while encouraging repeat orders.

Cost to Price Guidance (Wholesale & DTC)

• Wholesale pricing: Anchor to DTC benchmarks plus your channel margin expectations. For example, if a top‑line DTC brand sells at $119, your private‑label wholesale offer should be set below that while ensuring full TLC coverage and a target gross margin.
• Volume brackets: Negotiate scale breaks in 500/1,000/5,000 pair increments. Executive blanks, coating batch sizes, and tooling amortizations favor ≥1,000 pairs.
• Tiered coatings: Create a cost ladder—SR (entry), AR (mid), Super AR (premium)—and ensure additive impact on COGS is captured in your wholesale/DTC price ladders.

Practical Tips to Save Cost

• Material selection: Use CR39 unless prescription or safety requirements demand Trivex/PC or high‑index; CR39 offers the best executive lens cost profile.
• Coating rationalization: Standardize two coating tiers (AR and Super AR). Fewer SKUs simplify production planning and reduce scrap.
• Batch and tooling: Consolidate prescriptions into weekly batches to benefit from batch AR coating and reduce rework. Maintain standardized bevel and frame templates to minimize one‑off setup costs.
• Incoterms discipline: Use DDP when feasible to neutralize customs surprises and build accurate landed cost. Confirm HS codes early with your broker.
• Quality controls: Tight tolerances and clear QC criteria reduce returns/remakes. Build a low‑defect SOP and measure it.
• Returns and warranty: Cap at 0.5–2.0% of COGS in cost models; align with supplier warranties for quality defects to share risk.
• Logistics planning: Ship domestic with domestic ground once in‑country; for EU, consolidate shipments into EU hub to reduce friction. Avoid spot premiums unless margin‑accretive.
• Data‑driven mix: Track coating tier mix, return rates by material/coating, and rework by step; iterate your tiered pricing and SKU mix quarterly.

Next Actions

• Request supplier quotes using the TLC structure (materials, coatings, labor, logistics, warranty reserve), with volume brackets (500, 1,000, 5,000).
• Confirm HS codes and applicable duties/VAT for USA and EU shipments before finalizing Incoterms.
• Pilot with one prescription set and two coating tiers to benchmark yield, rework, and return rates before full rollout.

This framework will enable precise cost modeling and informed pricing decisions for executive bifocal lenses across USA and Europe.

Navigating Market Dynamics and Sourcing Trends in the Executive Bifocal Lens Sector

Market definition and fit

Executive bifocals are full-width, line-segmented lenses that combine distance (D) and near (N) or intermediate (I) and near in a single lens via a rectangular, top-to-bottom segmentation. This design maximizes the near/intermediate zone for desk-first wearers and eliminates the “bifocal window” typical of fused (round) designs. It is preferred by:
– Reading-intensive professionals (legal, finance, audit, lab work).
– Professionals requesting clear, consistent intermediate zones (D+I or I+N).
– Patients with specific prismatic requirements, anisometropia, and large near-work zones where a small add segment would be impractical.

Demand drivers

• Demographic shift: rising presbyopia in professional cohorts; aging workforce (US/EU).
• Hybrid work: persistent desk-based and screen-adjacent tasks sustain demand for I/N and D+N options.
• Value-based procurement: buyers seek predictable add segments, robust coatings, and minimal wait times.
• Compliance and QA: labs with ISO certification and robust QC reduce returns and streamline US/EU procurement.

Sourcing trends

• Digital surfacing becomes the default: better segment thickness control, fewer wedge artifacts, stable add power across the lens.
• Tiered coatings differentiate price/value:
• Scratch Resistant (SR): included, durable hardcoat for CR39.
• Anti Reflective (AR): improves clarity; standard for premium tiers.
• Super Anti Reflective (SAR): extended performance (smudge, water, oil resistance; enhanced light transmission).
• Material mix by segment:
• CR39: high-value base, good optical quality; widely stocked; straightforward manufacturing.
• High-index (1.67/1.74): thinner and lighter; favored for rimless and thin-profile applications; higher price.
• Trivex: impact resistance and lighter weight; often used for safety/active users.
• Fulfillment model:
• Send-in frame: control lens selection and quality; suitable for mid/long-run volume.
• Buy frame + lens bundles: faster lead times; easier for small and medium buyers.

Regional considerations (US/EU)

• US: ANSI Z80.1 (prescription eyewear) governs refractive power, tolerance, and labeling; US buyers expect AR/SR standard or tiered upgrades.
• EU: EN ISO 14889 and REACH requirements affect material and coating compliance; suppliers with ISO-certified QMS and documented traceability gain preference.
• Price bands:
• Entry: CR39 + SR; mid-tier: CR39 + AR; premium: CR39 + SAR or high-index/AR/SAR bundles.
• Lead times: digital surfacing shortens turnaround; bundling reduces fragmentation in ordering and logistics.

Supply chain and inventory outlook

• High-index stock is variable across suppliers; anticipate longer lead times and higher COGS in 1.67/1.74.
• AR/SAR capacity is robust; demand concentrated around premium executive bifocals and rimless mounts.
• Return drivers: coating defects, segment alignment issues, center thickness variability. Mitigate via:
• Clear measurement protocols for segment power and center thickness.
• Coating tier selection aligned with usage (e.g., SAR for desk environments with frequent handling).
• Frame-in options for complex prescriptions.

Sustainability and ESG considerations

• Material selection:
• CR39 manufacturing is energy-efficient relative to high-index; favorable for ESG targets.
• Trivex offers longevity and impact resistance; consider life-cycle benefits versus cost.

Frequently Asked Questions (FAQs) for B2B Buyers of executive bifocal lens

Frequently Asked Questions (FAQs) for B2B Buyers

1) What is an Executive Bifocal and how is it different from traditional flat-top bifocals?

Executive bifocals place the reading segment across the entire lower portion of the lens, creating a wide, continuous near zone. Unlike flat-top bifocals with a segmented “window,” the executive design provides consistent near power from edge to edge, suitable for distance/reading or intermediate/reading (computer) applications.

• Key differences vs. flat-top:
• Near zone width: 100% vs. typically ~25–38 mm
• Seam placement: smooth, uniform near segment at the bottom vs. abrupt junction
• Use cases: large desks, dual monitors, or where wide near coverage is preferred
• Visual trade-off: larger near zone may produce more lateral distortion and slightly higher thickness/weight at the lower edge

2) What material options are available and which are recommended?

• CR39 Plastic
• Refractive index: ~1.498
• Abbe value: ~58
• Specific gravity: ~1.32
• Best for: optical quality, lower chromatic aberration, lighter weight in minus powers
• Typical tint compatibility: yes (with appropriate tint processes)

• Note: May be available depending on supplier stock (regular price reference: USD 119; listed sale price: USD 119; reference regular price before sale: USD 229; availability status: sold out)

• Polycarbonate

• Refractive index: ~1.586
• Abbe value: ~29
• Best for: impact resistance, safety compliance, lightweight robustness
• Considerations: slightly more chromatic aberration; anti-reflective (AR) coatings are strongly recommended to mitigate visual dispersion

Recommended selection:
– CR39 for visual clarity and minimal aberration
– Polycarbonate for durability and safety (e.g., occupational use, safety frames)

3) Which coatings are recommended and why?

Coating options (as provided by source):
– Scratch Resistant (Included)
– Purpose: extend lens life and resist micro-abrasion
– Anti Reflective
– Purpose: reduce glare, improve comfort in artificial light, enhance readability
– Super Anti Reflective
– Purpose: further reduce glare, improve light transmission, and maintain cleaner lenses with enhanced hydrophobic/oleophobic properties

Coating recommendations by use:
– Office/computer: Super Anti Reflective for digital comfort
– Professional/reading: Anti Reflective or Super Anti Reflective
– Industrial/safety: Scratch Resistant plus Anti Reflective (AR helps under overhead lighting)

4) What frame styles work best with Executive Bifocals?

• Full-rim or thick-temple styles for durability and lens protection
• 8-base or moderately curved wraps to control off-axis aberration in the wide near zone
• Minimum lens sizes: approximate rectangle ≥49□18 mm or round ≥52 mm
• Avoid extremely small, round, or highly toric frames that reduce usable near coverage and can increase distortion
• Fit considerations: ensure stable fit, adequate nose bridge support, and vertical lens placement to utilize the full width of the near segment

5) What segment height should I specify?

Typical targets:
– Distance/Reading: lower segment height ~28–35 mm
– Intermediate/Reading (computer): lower segment height ~24–30 mm with intermediate addition
Note: Actual requirements depend on frame geometry, PD, vertex distance, and wearer posture. Provide frame measurement sheets or tracer measurements for accurate placement.

6) What measurements do I need to provide and how are they sent?

Required measurements:
– PD (monocular)
– Near add power
– Intermediate add (if applicable)
– Lens diameter, frame eye size, bridge, minimum B/segment height
– Coatings and material preference
– Coating placement notes (front/back AR; super AR if selected)
– Frame shipping details (if using “Send in my frame” option)

Acceptance methods:
– Frame drop-ship
– Frame sent-in package with copy of Rx and Rx card
– Digital order via supplier portal with digital tracer files

7) What compliance standards and certifications apply?

• Impact resistance (if polycarbonate is used): ANSI Z87.1 (US) and EN ISO 12312-1 (EU)
• AR and hardcoat processes: follow supplier specifications to ensure adhesive integrity and durability
• Anti-fog/scratch: industry best practices for chemical-resistant coatings

8) What are the product options, pricing indications, and turnaround times?

Configurations supported (source):
– Use application: “Distance and Reading” or “Intermediate and Reading (Computer)”
– Frame source: “Send in my frame” or “Will buy a frame from UseMyFrame.com”
– Coatings: Scratch Resistant (Included), Anti Reflective, Super Anti Reflective
– Sample configuration strings:
– Distance and Reading / Send in my frame / Scratch Resistant (Included)
– Intermediate and Reading (Computer) / Send in my frame / Super Anti Reflective

Pricing/availability (as indicated by source page):
– Listed sale price: USD 119.00 (regular price: USD 229.00)
– Status: Sold out (availability may vary)
– Note: Pricing and availability subject to change; contact supplier for current lead times and bulk pricing policies

Typical turnaround:
– 3–7 business days after receipt of frame and complete Rx (subject to lens stock, coatings, and order volume)

How to order:
