Fungus, mildew and dirt can grow on your glasses and become lodged around the edges of your lenses. Diligent and regular cleaning can help stop build-up; however it is impossible to completely prevent growth, especially if your lenses are exposed to a warm, moist environment. Care should be taken when removing mould from your lenses. Some mould and dirt may become lodged inside the eyewire or edge of your glasses frame around the lenses where a cleaning at home cannot remove all of the grime. Your optician or eyecare professional can remove your lenses from your frame and clean them in a special ultrasonic cleaner. Most optical offices will do this cleaning at no charge or for a nominal fee.

Place a few drops of dish soap in a sink filled halfway with warm water. Add 3 to 4 tbsp of white vinegar to the water and immerse your glasses. Allow to soak for at least 30 minutes.

Use your fingers in a circular motion and rub any areas of the lenses that are dirty with soapy water. Rinse your glasses with warm water and wipe with soft towel. If mould still remains on lenses, repeat process several times.

Place a few drops of dish soap on a wet, soft toothbrush and carefully scrub the edges of the lenses, being careful to not get the bristles on the front or back surface of the lenses, just the sides. This works best for rimless and thin edged frames.

Do not use paper towels or tissues made from paper to clean your glasses as paper products can scratch your lenses.
