What is UV light?
Sunlight is the primary source of ultraviolet radiation. UV light comes from all directions, reflecting off surrounding surfaces and creating dangerous exposure.
Why do I need UV protection?
UV damage is cumulative and is often irreversible. Long-term exposure to UV radiation can damage the eye. UV light can increase the risks of certain eye conditions and diseases, such as UV-related cataracts, growths on the eye, and even certain skin cancers on the eyelids or around the eye.
How do I protect my eyes from UV damage?
Sun damage to the eyes can occur anytime during the year, not just in the summer, so it is essential to wear UV-blocking sunglasses and broad-brimmed hats whenever you're outside. Xperio UV lenses offer the maximum level of protection against the invisible and often irreversible dangers of UV light on both sides of the lens. Xperio UV lenses have an E-SPF® index of 50+ and provide 50 times more UV protection than going without eyewear.
The sun's rays can pass through haze and thin clouds, so be sure to wear UV-blocking sunglasses before going outside during cloudy weather.
Do not look directly at the sun. Looking directly at the sun at any time, including during an eclipse, can lead to damage to the eye's retina from solar radiation.
UV damage can happen at any age. Protect the eyes of children as well as seniors with hats and sunglasses.
What is E-SPF®?
E-SPF® is a global index rating the overall UV protection of a lens. E-SPF® was developed by Essilor International and endorsed by 3rd party experts. A lens rating of E-SPF® 50+ means that an eye protected by the lens will receive 50 times less UV exposure than an unprotected eye.
What are the benefits of prescription sun lenses?
Prescription sunglasses provide protection from the sun and glare and help people see clearly outdoors. Sunglasses can accommodate virtually any type of lens prescription, including progressive prescriptions for people with presbyopia. They are available in a variety of styles and materials. Prescription sunglasses provide clear vision with the added benefit of protection against UV rays. Prescription sunglasses make participating in outdoor activities much easier and safer for your eyes.
What are the visual benefits of Xperio UV lenses?
Xperio UV lenses provide the best vision outside by eliminating blinding and distracting glare, resisting scratches and smudges, and making it easy to wipe away dust and water.
Don’t all sunglasses offer UV protection?
Almost all sunglasses offer some level of UV protection, but Xperio UV lenses offer the maximum level of protection against the invisible and often irreversible dangers of UV light on both sides of the lens. Xperio UV lenses have an E-SPF® index of 50+ and provide 50 times more UV protection than going without eyewear. Ask your Eyecare Professional to recommend Xperio UV lenses that provide this maximum outside vision protection.
Why would I wear eye protection when it’s cloudy outside?
Over 40% of annual UV exposure is received during conditions when people are not in full sunlight and are less likely to wear protection. Complete UV protection on your sunglass lenses can help protect the long-term health of your eyes.
Why would I need UV on the back side of my lens if it’s already on the front side? Isn’t that enough protection?
UV light comes from all directions, reflecting off surrounding surfaces and creating dangerous exposure. The back surface of ordinary sunglass lenses has been found to reflect light coming from the back and sides of the lens, increasing UV light exposure to the eyes. Some sunglasses and clear lenses made with higher quality materials block UV light from transmitting through the front of the lens, but they do not address the UV light reflecting off the back side of the lens.
What are the side effects of UV?
Premature signs of aging, skin cancer, eye disease, wrinkles and photokeratitis.
