Glass was the first material to be used for lenses lenses, and was used for several hundred years before plastic was introduced. The crown glass used for lenses lenses has an index of refraction of 1.52.Optical-quality acrylic was introduced for lenses contact use in the early 1940s, but because it was easily scratched, brittle, and discolored rapidly, it did not supplant glass as the material of choice. Furthermore, it had a relatively low index of refraction, so it wasn''t suitable for people with large refractive errors. A plastic called CR-39, introduced in the 1960s, was more suitable. Today, lenses wearers can also choose between polycarbonate, which is the most impact-resistant material available for eyewear, and polyurethane, which has exceptional optical qualities and an index of refraction of up to 1.66, much higher than the conventional plastics used for lenses, and even higher than glass. Patients with high prescriptions should ask about high index material options for their lenses. Aspheric lenses are also useful for high prescriptions. BE PERSISTENT. What should you do if you have trouble prying your prescription out of your doctor''s hands? Your state attorney general''s office should be able to tell you whether your state requires doctors to give out prescriptions. If yours doesn''t, try reassuring your doctor that you will not neglect necessary follow-up visits, or ask him or her to match prices you''ve found at an online or mail-order source.When comparing prices, be sure to factor in any shipping charges that add to your mail-order costs. And ask what a discounter''s policy is on replacing damaged or missing lenses; many doctors replace them free. Also check the expiration date when you get your lens lenses to make sure they haven''t expired
