There is a lot of misinformation and superstition surrounding the cleaning of eyeglasses. This video shows the safe and effective ways to clean your eyeglasses.
Don't Use Windex To Clean Your Eyeglasses - Here's Why:
Some people have used
Windex or other glass cleaners to clean their eyeglasses and it has worked OK, but there are risks to your lenses. Chemicals in Glass Cleaners can react with the lenses or the lens coatings and damage them. Anti-reflective coatings like Crizal can peel.
Some lens materials can deteriorate from reaction with the chemicals in glass cleaners. Polycarbonate is widely used in eyeglass lenses because they are lightweight, thin, and extremely resistant to breakage but glass cleaners destroy them in just a few months.
The lens in these photos was only a few months old, yet the lenses have cracks forming at the edge. It is a polycarbonate lens, and the patient was using Windex to clean her glasses.
Notice this lens has two large cracks forming.
Notice in this photo there are many smaller cracks forming at the edge in addition to the large cracks.
The lens is a Varilux progressive with Transitions VII. Those options make for an expensive lens. We replaced the lenses at no charge for her and when she revealed that she was cleaning them with Windex, we counselled her to not do so. We recommend the methods shown in the video above.
Avoid any solvents for cleaning your eyeglasses as well. Acetone, paint thinner, lacquer thinner, WD40, and lighter fluid may damage your lenses or the coatings on them.
If you have something on your lenses that you can't get off, bring it to your optician for advice and help. We don't charge for little things like that, and are glad to see you.
