1.61 Blue Block Lens

Our 1.61 Blue Block Lenses, made from premium MR-8 UV420 material, deliver exceptional optical clarity with a high Abbe value of 41, ensuring sharp, distortion-free vision. Designed with an aspheric profile, these lenses are thinner and lighter than traditional ones, providing superior comfort especially for high prescription users.

Equipped with advanced Hard Multi Coating (HMC), our 1.61 blue block lenses offer outstanding scratch resistance and durability, making them ideal for daily wear and demanding environments. Their excellent impact resistance ensures safety, particularly for rimless or semi-rimless frames.

Beyond superior vision correction, Crystal Optical’s 1.61 blue block lenses effectively filter harmful blue light and ultraviolet rays, reducing eye strain and fatigue caused by prolonged exposure to digital screens. This makes them the perfect choice for professionals who spend long hours in front of electronic devices.

How 1.61 Blue Block Lenses Protect Against Digital Eye Strain

Anti-blue lenses protect against digital Eye Strain in the following two ways:

Reflection ‌ : Coating the surface of the lens to reflect harmful blue light away.

‌Absorption ‌ : Anti-blue factor is added to the lens substrate to absorb harmful blue light. ‌

The Technological Features of 1.61 Blue Block Lenses for Enhanced Comfort

First, blue light filtering and eye protection function

High blue blocking rate: can block harmful blue light, reduce the stimulation of electronic screen blue light to the eyes, reduce visual fatigue.

Second, refractive index and lens design

Refractive index characteristics: 1.61 index is between 1.56 and 1.67, the lens edge thickness is about 20%-30% thinner than 1.56, but slightly thicker than 1.67, suitable for 200-600 degree myopia people.

Aspherical design: Using aspherical technology to reduce edge aberrations and improve visual field clarity, especially suitable for long office hours or scenes requiring accurate vision.

Third, coating and surface treatment technology

Multi-functional coating: The ultra-waterproof coating enhances the waterproof, stain and scratch resistance of the lens while maintaining high light transmittance.
