The quality of glasses is very good. The advantage of diamond trimming is that the lenses are diverse in shape and full of personality, which makes people wear them with temperament and good quality. The maintenance method of diamond trimming glasses is the same as that of ordinary rimless glasses. Usually you need to wear glasses with both hands, don't adjust the frames yourself. You can ask about the material of the lens. If it is a PC lens, you can rest assured when using it. Just wash the glasses with lens cleaner or detergent, and then rinse them with clear water. Do not dry-clean the lenses with lens cloth or paper towels.
