Sunglasses Offered by our Fremont Optometrists
Ultraviolet radiation can cause damage to unprotected eyes as soon as they are exposed to sunlight. Invisible to the naked eye, UV rays are comprised of three different light spectrums--UVC, UVB, and UVA. Although UVC rays cannot pass through the Earth's atmosphere, UVB and UVA rays can. Unfortunately, UVA and UVB rays cause harm to cellular DNA, promote cataract development, and are the main cause of eyelid cancer. For these reasons, your optometrists in Fremont urge everyone to wear sunglasses with lenses especially made to block UV rays.
Prescription Sunglasses vs. Non-Prescription Sunglasses
If you wear glasses or contact lenses, your eye doctor can provide sunglasses with lenses containing your prescription. With prescription sunglasses, you can see just as well as you can while wearing your contacts or glasses. We recommend everybody who wears eyeglasses to invest in a pair of prescription sunglasses, as this reduces the need for switching between the two. Prescription sunglasses are especially useful for driving and any outdoor activity.
Alternately, nonprescription sunglasses do not have lenses that correct vision issues. When choosing sunglasses, prescription or non-prescription, make sure that they are UV blocking.
Why Choose Polarized Lenses for Your Sunglasses?
Polarized lenses filter out bright glare that radiates off asphalt, water, snow, and grass. Polarized sunglasses are preferred by those who spend time driving, playing outdoor sports, fishing or visiting ski slopes while on vacation and are available in .75 mm and 1.1 mm strength. Although darkly tinted, non-polarized sunglasses may help reduce brightness, but they do not provide the protection against damaging UV rays that polarized sunglasses do.
How Damaging are UV Rays? Am I at Risk if I Don’t Wear Sunglasses?
Research into the primary causes of cataracts has found that intermittent exposure to ultraviolet light could significantly increase your risk of cataracts and/or macular degeneration. Cataracts are made of abnormal proteins that clump together, cover the retina and eventually impairs vision. Unless removed and replaced with a synthetic lens, cataracts gradually thicken and make it difficult to see clearly, even for people wearing corrective lenses.
Unprotected eyes exposed to UV rays may also suffer age-related macular degeneration, an eye disorder affecting a part of the retina called the macula. When the macula starts degenerating, your ability to see objects in your central vision field deteriorates. People with moderate to advanced macular degeneration may notice a cloudy, whitish spot developing in the center of their vision field.
