Overexposure to this radiation can damage the eyes and the skin around them, causing aging, wrinkles and, in severe cases, skin cancer (between 5 and 10% of skin cancers start on the eyelids ). In the long term, it can cause other eye diseases, such as photokeratitis, cataracts or macular degeneration. Visual health professionals, such as Javier Vega, warn of the need to protect our eyes, at all times of the year, especially in summer
When the heat starts, Sevillians have internalized the need to use sunscreen to protect the skin. Likewise, they are aware of the need to protect their eyes with sunglasses. However, UV radiation is always there, all day, every day. Without going any further, today, July 14, UV radiation in Seville will reach a factor of 9, and will probably reach 10 in the rest of this week, a very high risk of damage from exposure to the sun without protection.
UV radiation is potentially harmful, even in winter or on cloudy days, for skin and eye health. “We do not internalize the need to protect our eyes as much as our skin, when in fact it is just as important to prevent pathologies such as photokeratitis, cataracts, photoaging and alterations in the DNA of the skin”, explains Javier Vega, technical director. by ZEISS VISION CENTER Viapol.
The World Health Organization recalls that each year in the world, three million people lose their sight due to UV rays. Nearly half of blindness cases (48%) derive from cataracts, which in 20% of cases are aggravated by UV radiation.
It is a fact that only 1 in 5 people wear sunglasses when they go out, and it is also true that one of the easiest and most effective ways to prevent various eye diseases is to use glasses. with ZEISS UVProtect technology. “ZEISS is setting a new standard in eye care by including full UV protection on all of its clear lenses. ZEISS lenses offer UV protection up to 400 nm, in accordance with the UV protection standard established by the WHO. Or what amounts to the same thing, ZEISS crystals protect against UV rays like high-end sunglasses,” says Vega.
Currently, approximately 80% of clear lenses on the market do not offer complete UV protection. On the other hand, all ZEISS varnishes incorporate UVProtect technology and protect up to 400 nanometers, the limit recommended by the World Health Organization (UV radiation between 380 and 400 nanometers is the most intense and penetrates deeper into tissues )
If it is important for the whole population, in the case of children it is essential to protect their eyes from UV rays, since in their case, this has an impact 7.5 times greater than in adults. . Their lens is much more transparent and they also spend more time doing outdoor activities. Thus, a minor, before reaching the age of 20, accumulates 50% of the radiation he will receive in his lifetime (up to age 60). “Unfortunately, today only 1 in 5 glasses completely blocks UV radiation up to 400 nm. This means that the other 4 do not block ultraviolet radiation, or only minimally. glasses, creating a potential risk of damaging the eyes and skin.One of the easiest and most effective ways to prevent or delay the onset or progression of various eye diseases is the use of lenses with UV protection up to 400 nm, from childhood,” he concludes.
