Did you know that the idea that sunglasses only need to be used during hours of greater solar intensity or when the sky is clear is incorrect? Ultraviolet radiation is present every day of the year and can seriously damage the eyes if they are not properly protected. In addition to being considered a fashion accessory, it is essential to keep in mind that sunglasses are the only ones that offer effective protection for our eyes against harmful factors, such as UV radiation.
Nowadays, you can buy sunglasses almost anywhere. However, one aspect that is often overlooked when buying from street vendors or non-specialist stores is the quality of the lenses. It is important to note that, when buying sunglasses in places that are not specifically dedicated to optics, we are, most of the time, simply buying glasses with tinted lenses without any protection or treatment.
Although the eyes have natural defence mechanisms against UV rays, this protection is not sufficient due to the intensity and duration of the exposure to which we are subjected. For this reason, it is crucial to look for accredited eye care professionals, who can guide you in choosing certified lenses capable of blocking part of the light and providing less aggression to the eyes, improving sharpness and visual comfort.
Furthermore, sunglasses help prevent eye diseases, such as cataracts, the incidence of which is significant in the African population, due to the intense sun exposure that people in Africa are subject to.
