Did you know that sunglasses, or at least sunglass lenses, regularly need to be replaced?
According to a study conducted at the University of São Paulo, the UV protection that sunglasses provide deteriorates over time. You may adore your current ones, but if you’ve been rocking those shades several years, it might be time to get a new pair.
In addition to the UV-blocking properties, anti-reflective and anti-scratch coatings wear down, and the frame material may become brittle over the years.
What to Look for When Getting New Sunglasses
- Make sure they’re labeled 100% UV protection or UV400.
- Remember that cheap counterfeit eyewear may not provide much-needed ultraviolet protection and can be dangerous to your eyes. So, if the price of a renowned brand is too good to be true, it's probably a fake.
- Consider the size and fit of the sunglasses. Larger wrap-around eyewear is best if you regularly spend a lot of time outdoors, as this style blocks light from all directions.
