There are many lens material available to create your prescription eyeglasses. High index materials create thinner and lighter eyewear. Polycarbonate and Trivex materials have the best impact resistant qualities for safety. The patients' prescription, needs and desires as well as the optics and characteristics of each lens material must be taken into consideration when choosing the best lens material. Our staff will help you select the best lenses for your needs.
Polycarbonate lenses are thinner and lighter lenses than standard plastic and have excellent impact resistance for safety. Polycarbonate also has good ultraviolet light blocking included. These lenses work well for children, rimless glasses and safety eyewear. Polycarbonate lenses have an index of refraction of 1.59.
Trivex lenses are not quite as thin as polycarbonate, but better optical quality, excellent impact resistance and flexibility, and the lowest specific gravity for our floating sunglass line. Trivex material includes UV protection. The higher tensile strength of Trivex makes it frequently the best for rimless and drill mounted glasses. Trivex lenses have an index of refraction of 1.53.
High index lenses are for the thinnest lenses possible. A variety of materials from 1.53 to 1.74 index are available depending on the lens power and type needed. The gains in thickness reduction vary with the prescription needed in the lenses. High index materials all have ultraviolet protection built in. We will help you choose the correct material for your individual situation.
