Summer is in full swing and there’s one thing for sure — the sun’s rays do a lot of damage to your eyes. Well, you can provide protection as well as make a statement with a stylish frame by considering a few pointers on how to pick the right pair of sunglasses.
First, though, a bit about why you should always wear sunglasses.
Just as the sun’s ultraviolet (UV) rays can damage your skin, they can also harm the lens and cornea of your eye. Long term (as in years — the sun’s damage is cumulative) exposure to UV radiation increases your odds of getting cataracts and has been linked to macular degeneration, a degenerative (though treatable) disease of the macula that is essential for sharp vision.
And while you mainly think of sunlight as it travels from the sun, through the air and into your eyes, just as important to guard against is sunlight that bounces off of highly-reflective surfaces such as water, sand and pavement.
Sunglasses play a pivotal role in shielding the eye’s fragile tissue from UV radiation. Like sunscreen, sunglasses should be worn whenever you’re outdoors, year round.
Look for sunglasses with complete UVA/UVB protection
Choose sunglasses that provide full protection from UV light. Ask one of our opticians or make sure that the sunglasses clearly state one or more of the following:
- Lenses block 99% or 100% of UVB and UVA rays
- Lenses meet ANSI Z80.3 blocking requirements
- Lenses feature UV 400 protection
As we age, the probability that we’ll suffer from an eye disorder increases significantly. By age 65, about one-third of adults will have a vision impairment condition and by age 80, that percentage increases to 50% of us.
One of the most common conditions affecting older Americans is age-related macular degeneration or AMD. It’s the leading cause of blindness in adults over age 55. AMD results from the breakdown of the macula or small area in the retina at the back of the eye. Contributing factors to AMD include exposure to sunlight, smoking and even everyday contaminants in your environment.
One preventative solution to AMD are antioxidants. Research over the past decades has shown that eye health is linked closely to diet and lifestyle. Being overweight, diabetic, smoking, eating a high-fat diet and consuming alcohol excessively can all contribute to poor eye health. Eating a diet low in fruits and vegetables is also shown to be detrimental.
They’re a clouding of the lens inside the eye. They’re detected during a normal eye exam and are somewhat common with adults over the age of 40 (and increasing as we age). As they are so common and tend to progress slowly, your eyecare physician should monitor their progression as you grow older.
If you’ve ever had a sunburn on your skin, you’ve experienced the harmful effects of the sun’s ultraviolet (UV) rays. What you might not be aware of is the damage that these rays can cause to your eyes, especially the fact that the damage caused is cumulative — you may not realize the damage until years later.
Extended exposure to UV rays has been linked to eye damage, including these conditions:
Cataracts: Lab studies have implicated UV radiation as a cause of cataracts. It has also been shown that certain types of cataracts are associated with a history of higher ocular exposure to UV — and especially UV-B — radiation.
