The thesis is advocated by a new study by the Association for Research in Vision and Ophthalmology and the Medical University of Graz. Portuguese expert recommends the use of sunglasses.
An investigation by the Association for Research in Vision and Ophthalmology and the Medical University of Graz in Austria points to excessive sun exposure and unprotected as a cause of the iris spots that many people tend to present in the summer. The experts came to this conclusion after an experiment with 600 volunteers recruited at several municipal pools in the country. After responding to a questionnaire about sun protection care, they underwent an ophthalmologic examination.
The conclusions of the study leave no room for doubt. People who get sun more unprotected tend to have more spots inside their eyes. The scientists say, however, that unlike melanomas, they tend to be benign. The younger, darker-eyed people tend to be the most affected, with most brands appearing on the lower left side of the iris.
Although, at first analysis, do not represent great danger, the authors of the investigation call for protection of the eyes in periods of greater exposure to heat.”While skin damage caused by ultraviolet rays is more than known, its harmful effects on the eyes are not as commented. The direct incidence of ultraviolet rays in the human eye causes gradual eye lesions that can lead to total or partial loss of vision,”warns Eduardo Pinto, an optometrist.
“Cataract, for example, is one of the most well-known ocular lesions in the world and its occurrence may be related to exposure to ultraviolet radiation,” says Optivision specialist, the largest Portuguese optical group.”The use of sunglasses, in addition to aesthetic reasons, has the function of preventing the passage of these rays through the filtering of the sun’s rays,” says Eduardo Pinto, accustomed to dealing closely with the problem.
“In the case of adults, health risks are reduced. However, the continued use of inadequate lenses can cause discomfort, headaches and feelings of discomfort. So when choosing sunglasses, make sure the lenses are protected against UV rays. In general, the models have a manufacturer’s seal that guarantees UV protection of the lens, warns the optometrist.
Caring for the little ones
Using sunglasses is a precautionary gesture that, in the opinion of this specialist, should also extend to other optical devices.”It is important to note that it is not just the sunglasses that should have eye protection. Graduated glasses and clear lenses can and should receive treatment with filters that block UV damage,”says Eduardo Pinto.
“In children, attention should be increased, since the eyeball is still in formation,” warns the optometrist.”If the protection is not correct, vision problems can develop, changes can occur or even aggravate existing vision problems,” he says.”Ideal lenses for children should also provide 99% to 100% UVA and UVB blockage,” he adds.
