Your eyelids provide some protection against sunlight but not enough to stop UV radiation from damaging molecules in your eyes. Your cornea and lens also filter out some ultraviolet radiation but after filtering sunlight for 30 or 40 years, they also suffer damage and no longer work well to minimize irradiating light from the sun. That’s why the lens sometimes turns slightly yellow in adults over 50 and develops clumped deposits of proteins called cataracts. Eyelid cancer is another reason to protect your eyes during the summer. Squamous cell and basal cell carcinoma of the eyelids account for around seven percent of all skin melanomas. Basal cell eyelid cancer is known to spread to the eye unless treated in its early stages. Almost all cases of cataracts and eyelid cancer are attributed to a history of intermittent but intense sunburns and sun exposure. Obtaining sunglasses near Marietta at Classic Vision Care can also greatly reduce your risk for intraocular melanoma, macular degeneration, benign conjunctiva growths and corneal sunburn (keratitis).
What are Polarized and Nonpolarized Sunglasses?
Prescription or non-prescription sunglasses in Kennesaw are either “polarized” or “nonpolarized”. Polarized lenses for sunglasses provide 100 percent protection from ultraviolet radiation and eliminates intense horizontal glare. This allows vertical light to be more accessible to the eyes for increasing visibility without interference from blinding glare. Polarized sunglasses are favored by people who fish, boat, ski or jog because they work so well to reduce glare off water and snow, offers clearer vision and better contrast and improve perception of colors. Additionally, if you are highly sensitive to indoor light or are recovering from cataract surgery, polarized sunglasses can help reduce eye irritation due to light or to post-operative healing.
Nonpolarized sunglasses are standard sunglasses that are darkly shaded and reduce light intensity. However, since they do not counter the glare effects caused by horizontal sunrays, they may not be particularly suitable for wearing while engaging in water or snow activities. If you drive frequently, you should consider getting nonpolarized sunglasses near Marietta GA because polarized sunglasses tend to reduce the clarity of images made by dashboard LED or LCD displays. Nonpolarized lenses allow you see your dashboard clearly while driving during the day in bright sunshine.
