Why do I need UV (ultraviolet) protection in my eyewear?

If you are exposed to excessive amounts of UV radiation over a short period of time from the sun, welding machines, tanning beds, or lasers, you are likely to experience an effect called photokeratitis. Like a "sunburn of the eye", it may be painful and you may experience red eyes, a gritty feeling in the eye as well as other symptoms. Long term exposure to the UV radiation can be more serious. The effects are cumulative, meaning the longer your eyes are exposed to UV radiation without protection, the greater the risk of developing such conditions as cataracts or macular degeneration in later life.

What's the difference between polarized sunglasses and non-polarized sunglasses?

Polarized sunglasses eliminate reflected glare. They are especially appropriate for people who drive a lot and people who enjoy fishing, golfing, hunting, and skiing. For a demonstration of the benefits of polarization, come by our office and look into our NuPolar Polarized Lens demonstrator.

What are the benefits of AR (anti-reflective) lenses?

These lenses, that have been used for years in fine camera lenses, are particularly effective for reducing eye fatigue for computer operators and anyone driving at night. And, of course, AR lenses enhance the appearance by removing all distracting reflections. Front surface AR reduces glare for clearer viewing, less eye strain and fatigue, improves eye contact, and furnishes cosmetic benefits. Back surface AR reduces glare from behind the lens and is often used on premium sunwear to help reduce backside sunlens glare. AR coating will reduce the "concentric ring effect" of high-minus lenses.

I am over 40 and now need to wear bifocals. What's the difference between Bifocals and Progressive Lenses?

Bifocals are the lenses that have a line going partially across the lower part of the lens. They provide a clear distinction between the distance and near prescription. Unfortunately, they offer no intermediate (usually about arm's length distance) prescription. Progressive lenses provide all the benefits of bifocals but add the feature of continuous clear vision at all distances, including the intermediate range. Progressives offer the cosmetic advantage of appearing to be single vision lenses so they never reveal that the user wears bifocals. Because of their many benefits, they are becoming the lens of choice for bifocal and trifocal wearers.

I like to play golf. I have a hard time playing the game while wearing my bifocals. Is there a type of lens specifically for playing golf?

Yes, there is. In fact, all sorts of special lens designs are available for the special needs of sports enthusiasts. Polycarbonate is usually the material of choice for active sports. And, depending on your sport (like golf) and your eyeglass prescription, special designs and tints may be used to improve the way you see your sport.
