The Importance of Wearing Sunglasses

Sunglasses are more than just a fashion statement. They are an essential part of eye protection, especially when you are outdoors. The sun’s ultraviolet (UV) rays can cause serious damage to your eyes, including cataracts, macular degeneration, and pterygium.

Why are sunglasses important?

  • UV protection: UV rays are the most harmful type of radiation from the sun. They can penetrate the cornea and lens of the eye, damaging the retina, the light-sensitive tissue at the back of the eye.
  • Glare reduction: Glare can be caused by sunlight reflecting off of water, snow, or other surfaces. It can make it difficult to see and can also cause eyestrain.
  • Wind protection: Wind can dry out and irritate your eyes. Sunglasses can help to protect your eyes from the wind and keep them moist.
  • Eye comfort: Sunglasses can help to make your eyes more comfortable in bright light. They can also help to reduce eye fatigue.

How to choose sunglasses

When choosing sunglasses, it is important to choose a pair that provides adequate UV protection. Look for sunglasses that have the following labeling:

  • 99% to 100% UV protection: This means that the sunglasses block out 99% to 100% of UV rays.
  • UV400 protection: This means that the sunglasses block out all UV rays up to 400 nanometers in wavelength.

You should also choose sunglasses that fit well and that block out all side light. Polarized sunglasses can also be helpful, as they can reduce glare.

How to care for sunglasses

To keep your sunglasses in good condition, it is important to care for them properly. Here are some tips:

  • Clean them regularly: Use a soft, damp cloth to clean your sunglasses. Avoid using harsh chemicals or cleaners.
  • Store them properly: Store your sunglasses in a case when you are not wearing them. This will help to protect them from scratches and damage.
  • Replace them regularly: If your sunglasses are scratched or damaged, replace them. This will ensure that you continue to receive the full benefits of UV protection.


Sunglasses are an important part of eye protection. By choosing a pair of sunglasses that provides adequate UV protection and that fits well, you can help to protect your eyes from the harmful effects of the sun’s rays.

Additional tips:

  • If you wear prescription glasses, you can get sunglasses with prescription lenses.
  • If you are going to be driving, make sure that your sunglasses have polarized lenses. This will help to reduce glare from the sun’s rays on the road.
  • Children should also wear sunglasses, especially when they are playing outdoors.

By following these tips, you can help to protect your eyes and keep them healthy for years to come.
