Every lens undergoes rigorous multi-point inspection ensuring optical excellence.
Every EverClear lens passes through our comprehensive quality assurance system. No lens leaves our facility without meeting strict optical performance criteria and ISO compliance standards.
Digital lensmeter measurement confirms sphere, cylinder, axis, addition, and prism values match the prescription within ±0.12D tolerance.
Precise measurement of optical centre location and progressive corridor alignment ensuring proper positioning for frame fitting.
Comprehensive examination of both lens surfaces for cosmetic defects, inclusions, or manufacturing marks that could affect vision or appearance.
Multi-layer coating system verification including adhesion, uniformity, and optical performance characteristics.
Centre thickness and edge thickness measurements verified against specification with ±0.05mm tolerance for cosmetic and weight optimization.
Complete visual inspection under controlled lighting followed by secure packaging with full documentation and traceability.
EverClear lenses meet or exceed all applicable international optical standards for finished prescription lenses.
Ophthalmic optics — Mounted spectacle lenses. Complete compliance with prescription accuracy, optical quality, and durability requirements.

We stand behind every lens we manufacture. EverClear lenses are covered by a 12-month manufacturing warranty on lenses and coatings.
If a manufacturing fault is confirmed during normal use, we'll repair or replace the lens at no charge under our warranty policy. This includes defects in prescription accuracy, coating integrity, or material quality that result from the manufacturing process.
Your patients receive the same premium-grade optical performance found in branded lenses costing £100–£500 more, backed by rigorous UK quality control and comprehensive warranty protection.
