HOW TO CARE FOR YOUR EYEWEAR
As with any purchase, properly caring for the item will prolong its lifespan. The same thing goes for your eyewear. Do not leave eyewear in direct sunlight for extended periods of time. Doing so can weaken the frame causing it to break as well as potentially crack the lens.
Rinsing eyewear in cool water using a mild liquid soap is recommended occasionallry or when necessary UNLESS they have mirror lens. Be sure to use a soft, clean, absorbent cloth when doing this. Never use paper-based products to clean the lens of your eyewear. Doing so can cause scratches and or other damage that may not be able to be repaired. Lastly, be sure not use chemical cleaners, harsh soaps or detergents that may leave residue on the lens. Think about if like this, they protect you, so you should protect them.
