Scientifically engineered lens coating applied to the back of Bollé® lenses, eliminates annoying backside glare and ensures crystal clear optics.
thin layers of material added to the surface of a lens that reduce the amount of light refracted by the lens surface which reduces glare and improves optical quality. astigmatism: a condition caused by an irregularity in the shape of the cornea which prevents light from focusing correctly on the retina thereby causing blurred vision. Symptoms may include headaches, fatigue, eye strain, or blurred vision at certain or all distances.
A violet-colored coating on the back of a lens that prevents sunlight from coming in from behind and reflecting off the back of the lens into the eyes.
A light-absorbing metal layer (typically titanium nitride), deposited on top of metal or polysilicon, to improve photolithography performance.
