Lenses:
Blue-cut lenses are designed to absorb over 90% of blue light. (Below 420 nanometers which are more harmful)
Blue light is visible light with high energy in the range of 380 nanometers to 495 nanometers. This type of lens is designed to allow some blue light to pass through to prevent color distortion.
Index 1.61 (Upto 30% Thin lens)
Blue light blocking lenses filter out the sun’s harmful UV as well as harmful blue light.
These lenses block harmful high-energy blue light from all light sources and digital devices.
Filters out 100% UVA and UVB rays
These lenses are available with various lens designs and coatings.
Regular Anti-glare lenses block UV light up to 380nm, but adding a UV-blocking lens boosts UV protection to 100 percent for added safety, protecting from shorter wavelength blue light up to 420nm.
