Why Are Sunglasses Important?

You’re probably no stranger to wearing sunglasses on days when the sun is out so that you don’t have to squint against the bright sunlight. In addition to preventing us from straining our eyes on such days, sunglasses also prove to be a pretty cool accessory that provides an instant upgrade to your ensemble.

But there are several other reasons why sunglasses are almost necessary whenever you go out in sunny weather. Today we’re taking a deep dive into these reasons and advising you on choosing the right kind of sunglasses that are both fashionable and functional.

To prevent eyelid cancer.

Eyelid cancer refers to the kind of tumor that occurs on or in your eyelid. If you get constant exposure to the sun’s ultraviolet rays, you might experience this cancer in the form of swelling or thickening of the eyelid along with chronic infection. That may sound scary, but if you shield your eyes with a pair of sunglasses whenever you go out, there’s no need to fret!

To reduce chances of developing pterygium and astigmatism.

The UV rays from the sun are also responsible for causing the growth of pterygium, a mucous membrane over the white part of your eye that can potentially cause loss of vision. In addition, this growth of new tissue can change the curvature of your eye and hence result in astigmatism. Experts highly recommend that you wear sunglasses to prevent these conditions from happening.

To prevent cataracts.

Cataracts are a serious eye condition in which the surface of your lens becomes cloudy, and you become unable to see correctly. Research has shown that around 20 percent of cataract cases result from prolonged exposure to ultraviolet rays. To avoid this condition, you should never forget to wear sunglasses when it’s sunny outside.

To counter macular degeneration.

The macula is a part of your retina that allows you to see and process visual information in great detail. Macular degeneration occurs when continuous exposure to UV rays causes your macula to deteriorate. Over time, this can lead to vision loss and even blindness. Therefore, sunglasses are an absolute must to prevent this from happening.

Choosing the correct type of sunglasses

While picking your next pair of sunglasses, you need to make sure that you find a pair that complements your face shape. The rule of thumb here is that the form of the frame should be opposite the shape of your face. You’d also want to get a durable pair so that you don’t have to get new ones constantly. And lastly, you’d wish to get sunglasses with large lenses that provide 99-100% UV protection to shield your eyes from the sun’s ultraviolet rays properly.


Wearing sunglasses is one of the many steps that you can take to preserve your eye health. Another critical step that you can take is to get regular eye examinations from your local optometrist.
