Dark sunglasses are accessories worn by both men and women around the world. Some people wear sunglasses even in the evening, when the sun has gone down over the horizon. It’s quite understandable – good sunglasses can favorably correct the shape of the face and give you a special charm.

Sunglasses have become an integral part of fashion must-haves. But today, we will discuss only practical side of wearing sunglasses: in fact, do they really protect our eyes from the sun? Experts unanimously agree that ultraviolet radiation harms the retina of our eyes. It can cause burns of the retina and, as a consequence – a serious loss of vision and even blindness. Any modern man knows that ultraviolet rays and sun glare can harm vision. Good polarized sunglasses may help to avoid such situations. For example you can try Ray-Ban, DKNY, Puma polarized sunglasses. In order to get cheap models, look for Lacoste, John Richmond or Vera Wang sunglasses online.

However, UV and alternative polarized sunglasses both are very popular and provide protection from the sun’s rays. So what is the difference between them?

Benefits of sunglasses with polarized lenses

Sunlight is partially refracted and partially reflected. When the light is reflected from the mirror surface, such as water, metal, road, it produces a particularly strong glare. Such reflections lead to serious eye damage. In fact, such flecks of sunlight are often the cause of many road accidents.

Polarized lenses have several advantages over traditional UV sunglasses, which are designed to block UV radiation and reduce the overall brightness of the light according to their inherent characteristics. Normal UV sunglasses provide basic protection and relief of discomfort caused by the bright sun.

If you use polarizing lens, it is more beneficial for visual perception. In essence, polarized sunglasses block the light reflections that interfere with our vision. Polarized lenses reduce the sensitivity to very bright light and block glare. Thus, sunglasses with polarized lenses permit only vertical light rays to pass, which is useful to the human eye. In general, these flecks of sunlight are not particularly critical, so it is not necessarily to wear polarized glasses all of the time.

Polarized lenses:

  • Eliminate reflections that cause glare;
  • Provide protection from excessive exposure to light;
  • Provide high clarity and comfort;
  • Provide enhanced depth perception and contrast;
  • Improve visibility during poor weather conditions;
  • Provide maximum protection from UV rays.

When choosing sunglasses, remember that whatever model you choose: glass lenses or made of polycarbonate, UV, photochromic or polarized, expensive designer eyewear or cheap models, the main thing is to choose really good sunglasses that provide full protection against ultraviolet light.
