Some eyeglass lenses have protective coatings to prevent glare and protect the eyes against UV rays. If the coating gets a scratch in it, it can be distracting and annoying. You can have the scratch filled or remove the protective coating. Only plastic lenses, such as polycarbonate lenses, can have the protective coating removed. Do not attempt to remove the coating from glass. The products used to remove the coating will etch glass lenses or cause them to become cloudy, rendering them unusable.
Dip a soft cloth in a glass etching cream containing hydrofluoric. These creams are available at art and craft stores.
Wipe the cream over the lenses creating an even layer of the cream. Do not rub the cream into the lenses, but rather apply it to the top of the lenses.
Allow the cream to work into the lens for two minutes.
Mix a liquid soap, such as liquid dish soap or liquid hand soap, with room temperature water.
Rinse the glasses under cool running water, while wiping down the lenses with the soapy water to remove the glass etching cream.
Repeat the process until the protective coating is removed.
Dry the eyeglasses with a microfiber cloth once they are clean.
