In summer, sunglasses are an essential part of your outfit. That's not only because they look stylish, but also because they protect eyes from bright light. However, what many people don't realize is that damaging UV rays are much more dangerous in winter than in summer. In summer, green surroundings only reflect about 6% of light. For snow, though, that figure is nearly 95%. Only sunglasses with high-quality lenses provide eyes with effective protection against eye inflammation or more serious conditions. This is because sunlight, which contains high levels of UV energy, can cause damage to the retina. All of this means that money spent on high-quality sunglasses is a wise investment.
