The lenses are made of glass, CR-39 plastic which is a lightweight material very much like polycarbonate, and also the high index polycarbonate. Though glass is the most suitable material for lenses, they are not too popular anymore because they are heavier than the other materials and also more expensive. There are materials which cost less and are lighter which are popular for prescription sunglasses. Prescription sunglasses are more convenient than the clip on ones as the person would have to carry two pairs of glasses around otherwise.
Sunglasses with polarized lenses
These sunglasses are usually worn when the person needs to cut out the glare but have a clear vision. It is difficult to see with the glare in the eyes and one cannot make out what is behind the light as one gets blinded by the glare. Polarized glasses help by cutting out the glare and allowing the person a clear vision of what is ahead. Just like windshields, the polarized sunglasses have a protective second layer bonded to it and this allows only the vertical waves to go through it. These glasses help people who are on large surfaces of water, on snow-covered slopes and on stretches of sand like the beach to cut out the glare.
