In daily life, the lenses of frame glasses are blurred. Wiping them with toilet paper, glasses cloth or clothes corners is a habitual action of many "glasses people". Glasses experts said that the frame glasses should not be wiped dry and can be washed with clean water.
It is understood that at present, most glasses use resin lenses, but resin lenses are easy to wear and get dust, so we must pay attention to maintenance. Regular glasses shops have micro ultrasonic cleaning machines to clean lenses, but most people can't go to glasses shops to clean them every day.
If there are greasy dirt or unclean things on the lens, drop a drop of detergent on the lens, gently rub the lens with clean fingers, and then rinse it with clean water. If there are small drops of water on it, dry it with a soft paper towel or wipe it with a special mirror cloth for resin lens. The dirt in the slit between the mirror frames can be gently brushed with a soft old toothbrush. The lenses are cleaned once a day.
