Apart from looking stylish, the main function of sunglasses is to protect our eyes from the UV rays.

ONESEC provides 3 maintenance tips to help extend the life of your sunglasses.

1. Never wipe your eyewear lens with your clothes By wiping your eyewear lens with your clothes, the dust particles on your

lens and clothes will rub against each other and scratch the lens, which will reduce the life of your eyewear.

2. Always store your eyewear in its case Eyewear lenses are fragile and should be stored in a hard case when not worn.

3. Replace your sunglasses every 2-3 years.

Sunglasses also have an optimal life span. Under prolonged exposure to ultraviolet radiation, a pair of sunglasses' UV

resistance will diminish with time. For best results, it is recommended that you replace your sunglasses every 2-3 years.
