Wear Sunglasses to Prevent These 3 Eye Problems


Wear Sunglasses to Prevent These 3 Eye Problems

I used to play varsity tennis back in high school, which meant spending countless hours in the BLAZING Southern California sun. Since I was young and healthy, I never thought about wearing sunglasses to protect my eyes.

Fast forward to my first year of optometry school where I’m sitting in as a patient for my classmate to practice on. As I was thinking about what boba drink I wanted to get after class, I heard my friend say “Hey! You have a nevus!” 

Excuse me, a ne-what? Well, that sounds totally not normal. Turns out, a nevus is one of three eye problems that may occur due to excessive sun exposure:

1. Pterygium – A growth over the white part of your eye, which may result in redness, inflammation, and/or reduced vision.


2. Cataracts – A cloudiness within the lens in your eye, which results in foggy vision.


3. Nevus – A colored growth on/within your eye that may affect your vision, depending on where it grows. Similar to a mole on your skin, it may become cancerous over time.


Why does this happen? The sun emits three types of UV rays: UVA, UVB, and UVC. The outer layer of your eye does a great job at absorbing all UVC rays. However, it is unable to absorb all UVA and UVB rays.

As a result, these harmful UVA and UVB rays can penetrate past your eye’s protective outer shell and reach your eye’s innermost structures. These innermost structures are oftentimes essential for you to see clearly, so damage to these components may result in reduced vision, irritation, or inflammation.  

So, what can you do to protect yourself? Throw on a pair of sunglasses that block both UVB and UVA rays since your eye cannot fully filter them out on its own. Not only will a cute pair of sunglasses protect your eyes, but they can totally tie your outfit together for a nice day out during this summer!

In addition, we recommend wearing a hat to further protect your eyes from the harmful UVA and UVB rays. If you have any questions, feel free to ask any of our doctors or opticians at your next visit. We hope to see, serve, and connect with you soon!
