How do sun rays and UV damage our eyes?

Sunglasses may typically be viewed as a fashion accessory that forms part of your visual expression. But are you aware that the right sunglasses can also help you to maintain healthy eyesight by protecting your eyes from the harmful rays of the sun. How does it work? Read more to find out!

We’ve all learnt (most likely the hard way) that the sun is a force not to be reckoned with! After all, I bet we’ve all had a summer holiday in which dad, after one too many pints, fell asleep in the sun and next thing we’re the ones bearing the brunt of his moaning and groaning about his nasty sunburn! We’ve become accustomed to protecting our skin from harmful UV rays because we’ve heard it all before, “you’ll get leathery skin!”, “you’ll have wrinkles!” and so on. But, are we applying that same mentality when it comes to protecting our eyes?

Ultraviolet rays are harmful bursts of radiation exuded from the sun that vary in lethality such as sunburn, wrinkles and even cancer. However, it is often overlooked that UV rays can have detrimental effects to our eyesight by damaging the surface of the cornea through cataracts or macular degeneration. Fortunately, this damage can be avoided by wearing glasses that have UV protection! So, if we’re willing to take care of the beauty of our skin, why not protect the very eyes that allow us to see that beauty?

But, you may wonder, "the sun doesn’t bother my eyes much, so how neccessary are sunglasses really?" 

You still need sunglasses regardless!

Just because sun rays do not physically hurt or are bothersome doesn’t mean that the sun is not emitting damaging ultraviolet rays that deteriorate your eyes. 

You might assume that you are safe on cloudy days, but in fact, most ultraviolet radiation passes through cloud cover so even on cloudy days your eyes are still exposed to risk from the sun. Even in the shade, some UV rays will reach your eyes through reflection from buildings, sand, water etc…

However, you don’t have to wear your sunglasses all the time. The safest choice is to check the UV index for your area, which tells you how much UV exposure you will face that day on the basis of the weather forecast. If the UV index is below 2, the risk of exposure is minimal. The higher the index is, the more cautious you should be and wear sunglasses.

And how to make sure you are choosing the right sunglasses? Watch out! Most sunglasses offer only 70% protection against UV rays! Look for the confirmation of the 99% protection against UV rays either on the product itself or on the company’s website. The right sunglasses should protect you against both dangerous types of UV rays - UVA, and UVB.

Some people view sunglasses only as a fashion accessory and part of their expression, but not everyone knows that the right sunglasses can also help us to maintain a healthy eyesight since they are protecting us from the harmful rays of the sun. How does it work? Read more to find out!

Sun is finally out! You decide to go out, put on a sunscreen, take your sunglasses and you are ready for a great sunny day! But do your reading glasses have a protection against the UV rays? You have probably heard about the UV rays...but what are they exactly? Ultraviolet rays are dangerous rays coming from the sun, which cause sunburn, potentially cancer in cases of overexposure and they can also hurt our eyes if we don’t protect them! Ultraviolet rays can damage the surface of your eye, and it has been proven that UV rays are one of the risk factors for conditions such as cataracts or macular degeneration, which hurt our eyesight. The right sunglasses which have installed protection against the UV protect the eyes itself, but also they protect the skin on the eyelids and surrounding areas.
