How to know if your sunglasses really protect against UV

How to ensure your sunglasses protect against UV

Choose sunglasses with a UV400 label or equivalent certification that proves that both UVA and UVB rays are blocked. Information about UV protection should be available on the frame, packaging, or manufacturer's website.

It's also important to pay attention to the lens material. Tinted lenses can reduce the amount of light, but without proper UV filtering, they can increase the risk of eye damage. So compare different brands and check the specifications before you buy.

Also, remember to inspect your sunglasses regularly. Scratches and damage to the lenses can reduce UV protection. Use a case for storage to ensure your glasses remain in good condition.
