Prescription Sunglasses: How They Protect Your Eyes

The UV rays from the sun are going to negatively impact your eyes. It, therefore, makes sense to protect your eyes. Prescription sunglasses are designed to protect your eyes by limiting the amount of sunlight that hits your eyes. They are more than an accessory because they also make you look attractive. Just like you need protection from something like skin diseases, so too you need protection for your eyes.

Eyes are Vulnerable

We know that our eyes are vulnerable to UV radiation from the sun. modern research tells us that HEV or high-energy visible radiation leads to macular degeneration. This HEV is high-frequency light that is as dangerous to your eyes. It is almost as bad as the blue-light emanating from your electronic device screen. Of course, UV radiation is much more powerful and dangerous than blue light emanating from computer and electronic device screens.

Blue Light

Our eyes are not able to block or resist such lights. The result is you could develop cataracts and even cancer. You may think that staying in the shade can protect your eyes. This is not the way to protect your eyes. One option available to you is to wear wraparound sunglasses that are capable of blocking UV rays completely. These shades are made for the sole purpose of protecting your eyes. They are also a good fashion accessory. The lenses do not allow UV light to impact your eyes directly. You can tell your sunglasses are protecting you from the UV rays if you beam UV light through the lens towards money. If you can see the symbols, it means your shades are letting in UV light.

UV Ray Exposure

There are a few factors you need to know regarding UV rays exposure. Depending on the time of day and season of the year as well as your geographical location, your sunglasses will filter out the rays in a different way. You can also consult the UV Index made by the US National Weather Service. This index varies from 1 to 11 and higher. If you do not expose yourself to the sun more than normal, you have fewer worries to take care of. Depending on how exposed your eyes are to the sun, the risk varies.

Even cheap but good quality prescription sunglasses block UV rays. This means you do not have to spend a fortune to own a decent pair. If you expose your eyes to the sun for a prolonged time, you risk cancer of the eyelids and eyes. Once you buy your shades, your only worry is that over time, they may lose their ability to filter out the UV rays.

Finally, you need to choose between polarized sunglasses and UV sunglasses. They are not the same even though you may think they are. You need to make sure that you minimize exposure to the sun. wearing shades can help you stay out in the sun without risking eye problems. Just make sure you pick a pair that has UV coatings on the lens for maximum protection.
