There’s a lot more to sunglasses than simply being fashionable. First and foremost, they’re meant to protect your eyes from the sun’s harsh UVA and UVB rays. So while it may be tempting to just invest in a basic pair of sunglasses, the truth is that you need to go beyond looks and make sure that you’re getting the level of protection that will ensure the UV radiation doesn’t penetrate into your eyes. This is why designer Prada and Tom Ford sunglasses are popular options.

How UV Radiation Affects Your Eyes
To understand the importance of buying a high quality pair of sunglasses that provides you with adequate levels of protection against UV rays, you need to know what radiation actually does to your eyes.

  • UVA rays are known for having lower energy when compared to UVB and UVC rays. However, these rays are able to easily pass through your corneas into the lenses and retinas of your eyes. Therefore, being overexposed to these rays can potentially lead to macular degeneration and certain types of cataracts.
  • UVB rays consist of longer wavelengths, but they still have lower energy when compared to UVC rays. These are partially filtered by the Earth’s ozone layer. However, some of these rays still reach the surface of the Earth and can stimulate melanin production even in low amounts. These rays are what cause you to get a tan when you sit in the sun for extended periods. Higher amounts of UVB rays can lead to skin cancer, discolorations and wrinkles on the skin, as well as damage to the sensitive skin of your eyelids.
  • The most harmful type of radiation from the sun is in the form of UVC rays, which are almost completely blocked out by the ozone layer. However, because of damage done to the ozone layer, these rays could reach your eyes and cause health problems.

What to Look for When Buying Sunglasses
Now that you know the risks caused by UV radiation, you can shop for the appropriate sunglasses to protect your eyes from those harmful rays.

Search for lenses that provide at least 99% to 100% protection from both UVB and UVA rays. The sunglasses should have details right on their label, so if you pick up a pair that lacks this information, don’t bother purchasing it.

The degree of darkness and overall colour of the lenses don’t have an impact on the lenses’ ability to block the radiation, so you can really go with whatever lenses you prefer, from polycarbonate and polarised lenses, to blue-blocking and gradient lenses, to name a few.

Protect Your Eyes from All Angles
To really protect your vision and the health of your eyes from all angels, opt for a pair with wide lenses that wraps around your face and fits closely to your face so that it can block radiation from all sides.

With the right strategy, you can find the highest quality sunglasses that will serve to help you look great and protect your vision at the same time.
