Hold with Two Hands
Using both hands to remove your glasses from your face will help prevent frame misalignment and loosening of the fit over time.
KEEP WITH CARE
Store your glasses in a hard case. If you put them down without a case, make sure lenses are facing up to prevent scratching. And as you would probably guess, a hot car or any spot in direct sunlight is not an ideal storage place.
LIQUID + CLOTH = CLEAN
Use glasses cleaner or warm water and a bit of dish soap. Avoid using saliva, paper towels or tissues.
