Caroll asked: How can I get the film off my reading glasses?
Glasses 
are exposed to a variety of oils from our face, hair and hands. Over time, these oils can build up and cause a film over the surface of the glasses. Removing it is simple and takes only a few seconds.
You Will Need:
- Glass lens cleaner or
- Window cleaner
- Soft, lint free cloth
- White vinegar
Steps to Clean the Glasses:
- Spray a small amount of lens or window cleaner on each lens of the glasses. If your lenses have any coatings, refer to the manufacturer’s recommended cleaning solution. Do not use window cleaner on coated lenses as it may remove the coating.
- Use the soft cloth to gently wipe away any debris or oils from the surface using a clean, microfiber cloth.
- Repeat until the film is removed. If the film is stubborn, try cleaning with white vinegar instead.
Additional Tips and Advice
- Plastic lenses are much more susceptible to getting fine scratches on the surface. Over time, these tiny scratches begin to look like a film on the surface of the lenses. Unfortunately, once this damage is done it is not reversible. To avoid these minor scratches, use lens cleaners that are safe for plastic lenses and always use a soft cloth, such as a microfiber cloth. Even tissues or paper towels can leave fine marks on the surface that will result in a dull finish over time.
- Make sure you clean or replace your cleaning cloths often or you may end up redistributing the oil back onto the lenses.
Dish soap and water worked miracles to get the oily film off my glasses. Thanks for the tip.
What can I use to get under the oil that’s in the glasses, stuck inside the lenses? There is oil on the inside. Is there a way to remove that oil?
Nathan,
White vinegar is very effective at cutting through oil, but you may not want to use it if you have coated lenses as it could also remove the coating. Otherwise, you can try using just warm/hot water and some mild soap to rinse it out. Warm water cuts through oil better than cold water.
The blue dish detergent with warm water worked best.
Hi. How do I remove navel oil off sunglasses? Please help me.
Marlise,
Wash them with a some ammonia-free dish liquid and warm water, then dry them with a soft cloth. Do not use hand soap as it often contains alcohol, which can damage lens coatings. It’s best to use a cloth like flannel or microfiber to avoid scratches. You want to dry them to avoid water marks and also to prevent any metal parts from rusting.
