Eyeglass Lens Materials:
Most people refer to this type as “plastic” lenses. This lens is light weight compared to glass (which for safety reasons we NEVER recommend), and may be made in just about all prescriptions.
These lenses have 2 focal points corrected for the patient. The top portion is for distance correction and the bottom half of the lens is for near vision.
A lightweight and thin option, Trivex is preferable to polycarbonate. It is impact resistant for safety, thin for ascetics and optical superior for your vision.
Because of the way this material bends light in a different way than plastic lenses, your lenses will be thinner than the same prescription in plastic lenses. These lenses also have the added benefit for those frequently outdoors, under fluorescent lights, or using computers in that they filter ultra violet light naturally, blocking 99% of the damaging light.
The higher the index of refraction the quicker the light will pass through a lens, so less actual lens material is needed meaning the higher the index, the thinner the lens. These lenses are helpful in higher power prescriptions.
