6 tips to protect the eyes from the sun
Just as we are aware of the protection of the skin against the sun's rays, in the eyes we must also pay attention to them, and especially, in times of greater exposure, as in summer. A prolonged exposure to the sun without proper eye protection can lead to burns on the cornea (photokeratitis) or conjunctival damage such as photophobia, red eye, tearing, etc. With these 6 tips to protect your eyes from the sun you will avoid these risks
The damage can start at the surface of the eye, the cornea, and in the long term induce the formation of skin cancer in the area of the eyelids and increased risk of developing melanomas in the eye, such as choroidal melanomas. In fact, it has been shown that exposure to UV-B radiation increases the risk of cataracts, explains Dr. María Capote of the Ophthalmology Service of La Milagrosa Hospital in Madrid.
The World Health Organization states that "more than 80% of the exposure to UV radiation that occurs throughout life is reached before age 18." "It is clear that from this evidence and taking into account that the radiation accumulates throughout life, The use of protection from childhood, maintained throughout life, is extremely important, "says Dr. Capote.
Children, like adults, if they are going to spend a lot of time exposed to the sun, should protect their eyes. The use of sunglasses and caps with visor, is essential.
6 tips to protect the eyes from the sun
1. The glass of the goggle must comply with the CE and filter regulations. The color of sunglasses is not synonymous with UV filter. The CE mark (is the minimum guarantee standard) and the filter number they have (from 0 to 4) must appear clearly.
2. Choose the appropriate color of the spectacle lens. A dark glass does not mean that it protects better. In fact, a very dark glass but without the proper filter allows UVA and UVB rays to pass because the pupil is more dilated as the dark glass.
3. Wear sunglasses on cloudy days. In conditions of little sun there is also presence of UV rays.
4. Adapt your protection according to the need of each environment. Filters 2,3 and 4 are the most suitable for outdoor exercise, sun exposure on the beach or mountain and water sports and high mountains. However for a prolonged exposure to the sun, crystals with ultraviolet filter of 400 nanometers are recommended, stops 100% of the UV rays, and polarized crystals are not necessary.
5. Never look directly at the sun. Looking directly into the sun, even during an eclipse, can cause irreparable damage to the eye.
6. Special care with the eyes of children. Children should also protect themselves from the sun's rays and can wear sunglasses at any age.
