Convex Vision Specialty Lenses — Solving the Cases Your Standard Catalog Can't
Every practice eventually hits a case that standard single-vision or progressive lenses can't handle — extreme prescriptions, unusual professional visual demands, or both. This is exactly the category where Convex Vision differentiates: solutions for the orders your standard suppliers can't fill.
Who Needs Specialty Lenses?
Two patient profiles drive this category:
Extreme prescriptions — up to +50 diopters, cylinder up to 15 diopters, prism up to 20 diopters
Professional visual requirements — pilots needing clear sightlines to both instrument panels and overhead controls, plus other professions with non-standard visual field needs
These cases demand real manufacturing expertise — getting a thin, cosmetically acceptable lens at extreme powers is a genuine technical challenge, and it's exactly where a lot of practices end up stuck searching multiple catalogs for a viable option.
The Cosmetic Problem — and Why It's a Sales Opportunity
At high prescriptions, standard low-index lenses (1.50) get thick fast — creating the "magnifying effect" that makes eyes look unnaturally large or small through the lens. Beyond the aesthetic issue, this often becomes a real source of patient discomfort and self-consciousness, and it's frequently the reason high-prescription patients delay getting new glasses or avoid frame styles they'd otherwise choose.
Higher-index specialty lenses (up to 1.67) solve this directly: thinner, lighter, and far less distorting at the same prescription. That also means the patient isn't limited to specific frame shapes to hide lens thickness — a real value-add you can use to justify the upgrade in the fitting room.
Comparison point worth using at the dispensing table: a standard 1.50-index lens at sph. -6.00/cyl. 4.00 vs. a Convex Vision specialty lens at sph. -6.00/cyl. 8.00 — the difference in thickness and weight is immediately visible to the patient.
Key Takeaways for Your Team
High diopter values require true custom-made lenses, not standard stock
Certain professions (pilots, editors/graphic designers, electricians) have specialty visual needs independent of prescription strength
Aesthetics are achievable even at high prescriptions — this isn't a trade-off patients have to accept
Higher refractive index = thinner, lighter, better-looking lens at the same power
Stop the Search — One Source for Rare and Unusual Prescriptions
If your practice has been piecing together specialty orders across multiple manufacturer catalogs, Convex Vision consolidates that into a single source.
Specialty lens categories available:
Custom-made, high-strength lenses
Plano-concave / convex
Plus lenticular lenses
Freeform lenticular lenses
Bifocal, trifocal
Slab-off designs
Franklin designs
Pilot 2.0
Pilot 2.0 — Designed by Pilots, for Pilots
Standard progressive lenses don't support the upward gaze pilots need to read overhead cockpit controls. Pilot 2.0 solves this with a design optimized for distance, intermediate, and near vision — critically, with clear near vision in both the upper and lower zones of the lens, not just the bottom.
This gives pilot patients full flexibility to read instrument panels and overhead controls without the visual compromises a standard progressive would force.
