Frequently Asked Questions
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 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 or people who enjoy fishing, golfing, hunting, and skiing.
What are the benefits of anti-reflective lenses?
These lenses have been used for years in fine camera lenses and are particularly effective for reducing eye fatigue for computer operators and anyone driving at night. Anti-reflective lenses enhance the vision by removing all distracting reflections. Front surface anti-reflective lenses reduce glare for clearer viewing, eye strain and fatigue, improve eye contact, and furnishe cosmetic benefits. Back surface anti-reflective lenses reduce glare from behind the lens and are often used on premium sunwear to help reduce glare.
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 prescription. Progressive lenses provide all the benefits of bifocals but add the feature of continuous clear vision at all distances, including the intermediate range.
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. All sorts of special lens designs are available for the special needs of sports enthusiasts. 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.
I’m on a computer or digital device all day. How does it affect my eyes?
Computer work can cause eye strain including blurry, watery, tired eyes and can also lead to macular degeneration, cataracts, and eye lid cancers later in life because of the harmful blue rays emitted from digital devices. Dr. Dalesio recommends 20/20/20, which means take a break every 20 minutes and look 20 feet away for 20 seconds. Also consider Prevencia Lenses. They deflect 20% of the harmful blue-violet light and resist glare, scratch, smudge, dust, water, UV rays, and provide superior clarity of vision.
