Several lens treatments are available to enhance your lenses and to provide your eyes with protection and clearer vision. Several of these treatments are:
- Scratch protection
- UV blocking
- Anti-reflective coatings
cratch-resistant coatings enhance the value of all hard resin (plastic) lenses and minimize scratches. A variety of premium lenses now include factory-applied scratch coatings, which give the added security of a warranty. We recommend using these lenses whenever possible.
Ultraviolet Block Coatings
Ultraviolet radiation from the sunlight can harm the human eye. Your eye is more sensitive to these harmful light rays than your skin, and it is important for everyone to have ultraviolet protection in their ophthalmic lenses. It is thought that the ultraviolet wavelengths of light play a role in the development of cataracts and macular degeneration of the retina. Children should all wear protective sunglasses or have this filter added to their glasses. The UV filter itself is clear and does not alter the appearance of the lens. Several occupations have an increased risk due to the use of UV energy, and anyone who works outside should use this inexpensive feature to prevent damage to the structures of the eye.
Anti-reflective coatings are multi-layer coatings of gasses applied under a vacuum on the front and back surface of the lens. All lenses will provide clearer vision with less reflection if an anti-reflective coating is applied. High index materials should have an anti-reflective coating to improve appearance and function. Untreated lenses will only transmit 88% to 92% of light, but coated lenses will transmit 99.5% of light while reducing reflections. In the past, these coatings would scratch easily and were difficult to keep clean; however, new advances have addressed these problems and the new Crizal anti-reflective coating is very durable and easy to clean.

Tinting an ophthalmic lens can provide many important uses. Many people tint lenses to help with the brightness of the light. Others use special tints to enhance vision for specific tasks such as hunting and driving. Some would like to have lenses that change from light to dark and reduce the need for sunglasses. Now, new photochromatic lenses are available in glass, plastic, and high index materials.
