These days, the solar radiation it rises even on cloudy days, so it is important to protect the skin and eyes, especially in the case of children, the elderly, or those with clear skin and eyes.

The ophthalmology expert and Ultravision medical technologist, Rodrigo Sierra, explains that it is necessary to take precautions to avoid problems ranging from inflammation of the cornea, to damage to the retina. "UV radiation can cause cataracts and aging of the retina and lens," he says.

For the specialist, the use of sunglasses with UV filter and hats is essential. And it specifies that “over time, the effects of the sun can deteriorate the eye tissues. The UV rays that cause eye damage are those of type A, which most affect the lens, and those of type B, which are related to more severe burns, ”he says.

“Prolonged exposure to the sun without protection causes the retina and lens to age faster, among others, along with increasing the incidence of cataracts and age-related macular degeneration. Even, in some cases, it can cause eye tumors and cancer in the surrounding skin, ”he adds.

Likewise, if the exposure is without lenses and prolonged, the sun's rays can cause keratitis of different types, a disease that gives the sensation of sand and dry eye, even red eye.

Pterygium can also occur, which consists of benign growth of the conjunctiva tissue, which can cause pain because of the possibility of the eye swelling and turning red.

The specialist gives some recommendations on how to protect the eyes from the sun:

– Children under 2 years should not be exposed to the sun.

– Children over 2 years old and adults are always advised to use sunscreen.

– Wear a hat to be outdoors.

– Wear lenses whose label specifies that they have over 85% absorption of UV-B rays, which are the most harmful. If they say "UV 400", it means that they block at least 99% of UV rays. On the other hand, if they indicate that they are of “cosmetic” use, they block around 70%, which is not enough. It is also important to know that darker lenses are not necessarily better, since UV protection comes from an invisible chemical, and not the color of them.
