If you wear eyeglasses and occasionally see spots in front of your eyes, you might want take your glasses off before you hit full panic-mode. What you are seeing is not necessarily a floater or signs of eye disease, but a simple smudge on your glasses. Most people get smudges on their glasses at one time or another, and removing the spots is easy. However, learning to take care of your glasses and prevent smudges in the first place, is even easier.
Wash your hands with soap and water and dry them well with a towel before handling your glasses. The natural oils on your fingertips can cause smudging on the lenses of your glasses. Use hand lotion only after you have put on your glasses.
Avoid touching your face when wearing your glasses. In addition to your body’s oils, cosmetics on your face, including makeup, moisturizing lotions and sunblock, can rub off onto your fingers, leading to smudged glasses.
Clean your eyeglasses properly with a soft, lint-free microfiber cloth or pre-treated eyeglass cleaning cloths. Abrasive materials like paper towels can contribute to scratching and smudging of the lenses. Clean your glasses several times each day to prevent permanent damage from dust and lint.
Store your glasses in a hard case when you are not wearing them. Smudges are much more likely when the glasses are exposed to dirt, dust and spills without protection.
Ask your eye doctor about protective coatings that can be used to prevent smudging. Purdue University reported in 2007, that a polyethylene glycol-based material was being studied for use on windshields and eyeglasses to prevent smudging and fogging. Similar coatings may also reduce the instance of smudging.
