Disinfecting your eyeglasses and sunglasses is easy to do. In addition to seeing clearly through lenses that are free of smudges and fingerprints, nowadays we are doing everything we can to reduce the risk of germs on whatever we touch - especially anything near our eyes.
On our own eyeglasses and sunglasses, we use a solution of 70% isopropyl alcohol (aka: rubbing alcohol). This is the same solution many lens labs use. Spray the solution onto the lenses and frames, buff dry with a clean microfiber cloth. We like rubbing alcohol for a variety of reasons:
1) It is widely known to kill germs, bacteria and viruses.
2) It has proven safe to use on high quality lens materials and lens coatings, and on high quality metal and plastic frames.
3) It is commonly available.
As a precaution, we recommend using a small amount of isopropyl alcohol on the tips of the temples to ensure that the rubbing alcohol solution will not damage the frame material or colors.
Alternatively - if you don't have isopropyl alcohol or if you are concerned about potential damage to your lenses or frames, we recommend washing your eyeglasses or sunglasses with a drop of mild dishwashing soap and warm water. Be sure to dry your lenses with a clean microfiber cloth (not paper towels or a t-shirt). In addition to washing away germs, cleaning your eyewear with dishwashing soap has the added benefit of removing oils, smudges and other grime that can accumulate on your lenses and frames.
