Glassic Answers: Do Sunglasses Expire?

As eyewear enthusiasts the thought might have crossed your head: Do Sunglasses Expire? Well, there is no sure proof that sunglasses expire, but they might lose their key functions over time. 

In a study conducted by the University of São Paulo, Brazil, they found out that wearing your sunglasses everyday can lower things like the UV protection, and more. But it’s not mentioned anywhere that sunglasses expire. That's not true.

Make sure you take good care of your sunglasses. Scratches and dings on the lenses will affect your vision for sure. Also, it's recommended that you change your sunglasses every year, or at least in two years.

Changing your sunglasses has two advantages—one, you will get to update your style and two, and the most important point, your eyes will be properly protected from the sun (if at all the fiters are damaged)

Here are a few tips you can follow the next time you buy sunglasses:

  1. Remember, not all sunglasses are created equal. Every pair is crafted differently. For instance wider frame give you more protection from the sun than smaller frames.
  2. Make sure you buy sunglasses that are polarised and offer 100% UV protection for superior clarity and comfort.
