CARE
To avoid damage, never clean your eyeglasses with paper towels or clothing or alcohol, and also avoid using household detergents or soaps. While a few mild soaps don't harm lenses, today's extra strength soaps are powerful enough to slowly disintegrate lens coatings

NOTE
Size for manual measurement, there may be a 0 to 1 cm error, belongs to the normal phenomenon. Thanks!
