Ultraviolet Radiation and Sunglasses

With the onset of winter, the days become more cloudy and the use of dark glasses becomes less frequent. However, experts point out the need for use even when the sun is not apparent. "At all times of the year, summer or winter, even with cloudy days, there is the emission of sun rays and it is necessary to protect our eyes in some way," says Ana Paula Canto, an ophthalmologist.

According to her, the accessory is as impermeable as the sunscreen to the skin. "Just as dermatologists are talking about getting sunscreen on the skin, we, ophthalmologists, recommend wearing sunglasses with ultraviolet protection for the day," he says. The protection of UV-A and UV-B should be 99 to 100% and should block 75% of the light reaching the eyes, which will protect them from the effects of radiation over the years.

The director, Dr. Marco Canto, emphasizes that it is not enough just to wear dark glasses, it is necessary to have a product of good origin. "It is advisable that the purchase should be made in specialized places. The glasses without the correct protection allows to pass a greater quantity of UV rays, because with the darkening provided by the lens causes the pupil to dilate even more ", alert. According to the ophthalmologist, the price of the glasses can determine the quality and technology used for better protection. "The product being falsified or marketed for a low cost normally does not have ultraviolet protection and quality, therefore, impairs vision."

To know if the product is of quality, the consumer must observe the seal that attests the UV protection. "Regardless of the brand, if the glasses have the proper protection, it will be beneficial. If they are only dark, they will end up hurting the vision, much more than helping, "explains Dr. Ana Paula. The ophthalmologist points out that the sun's rays contradict macular degeneration and the formation of cataracts. "We have to avoid exposing ourselves to the sun without sunglasses. By using them we are preventing the onset of these diseases, "he teaches.
