Experts from the University of Alicante (UA) have discovered that extended exposure to the sun increases the hazard of setting up alterations within the lens by 4%. Determining the right pair of sunglasses can lessen such complications.

Despite that majority of the unsafe radiation from the sun is absorbed by the atmosphere, sufficient ultraviolet rays reach Earth’s surface to cause skin burns and eye complications in the retina and cornea. On this experience, reports highlight that every hour spent uncovered to the sun in the summertime increases the risk of creating variations within the lens by 4%.

But how will we decide upon a correct pair of sunglasses?

One of the greater ‘musts’ is that the glasses should undergo the European ‘CE’ seal, on the grounds that this means that they adhere to European safety standards.

Further advice from UA professor David Piñero urges us to not forget “that sunglasses are very important for visual health and, therefore, their purchase should be supervised by an optician-optometrist.

Another important factor to grasp when you are buying part of sunglasses is what filter class you need. This relies on your vicinity and undertaking. In response to European regulations on sunglasses, UV filters are labeled into five categories, from zero to four.

For example, if you are driving, you may want to use a class 1, 2 or 3 filter lens, relying on the conditions; not a 4, because this will intervene with the way you see traffic signs. According to Piñero, in the summer in Alicante a category 2 or 3 filter is more than enough, though if we’re going out onto the water or into the mountains, where light is reflected much more strongly, protection level 4 would be advisable.

Certain care must be paid to the glasses worn by children and old people. Children are specifically sensitive to ultraviolet radiation, considering that the lens continues to be transparent until adolescence. Category 2 or 3 is encouraged and very sturdy lenses and frames. Old people must put on the same category lens.

Just as cost isn’t a trademark of quality, neither is the colour of the lens a trademark of the level of protection provided. According to Piñero, There are very dark lenses that do not correctly filter ultraviolet light, leading to greater pupil dilation and an increase in the radiation that enters the eye.

Ultraviolet radiation is a risk factor for our eyes and ” has an accumulative effect that can, in some cases, set off problems in the photoreceptors in the retina (the rods and cones), progressively bad vision, macular degeneration, or the onset of pterygion, where tissues invade the cornea, known colloquially as Surfer’s Eye.
