|
| Plastic- This is the most frequently used lens material. Plastic lenses are light in weight and very durable when coated with scratch protection.
They provide virtually the same optical quality as glass and are much more impact resistant. They can be easily tinted to almost any color. |
|
| Polycarbonate- These lenses are the most impact resistant lenses available and are therefore used for children under the age of 18. The lenses are lighter in weight than plastic and come with scratch resistant coating and ultraviolet protection already applied. The optical quality of polycarbonate is less than that of regular plastic in higher lens powers. |
|
| High Index (Thin and Light)- These lenses were designed to give people with stronger prescriptions a thinner, more desirable cosmetic appearance without compromising optical quality. They are lighter in weight than traditional plastic lenses and also come standard with UV and scratch protection. |
|
| Hyper Index- The newest optical material available is a 1.66 hyper thin lens giving patients with prescriptions over -7.00 a very, very thin lens with great optical quality. These lens are twice the cost of high index, but offer patients with previous concerns about lens thickness a terrific, cosmetic alternative. |
|
| Glass- In years past, glass was the only lens material available. Because glass lenses generally weighs twice that of plastic and because they are not nearly as safe, they are rarely used today. |
|
| Photochromatic- These lenses change in color when exposed to different light conditions. They are available in both plastic and glass with all bifocal options. The glass lenses react to barometric pressure and the plastic responds to the UV light to which they are exposed. The degree of darkness varies with each lens type. |
|
| Polarized Sun Lenses- These lenses offer a significant optical advantage over ordinary tinted sun lenses. The light is filtered through a polarized lens, therefore giving the wearer better contrast and significantly reduced glare. They are great for driving and are ideal for those participating in water sports. |
