How to Clean Your Glasses Without Scratching Them
Most lens damage does not happen suddenly. It is often caused by simple habits repeated day after day, such as wiping the lenses with a shirt, using a dry tissue, or cleaning them incorrectly. Over time, these habits can scratch the lenses or damage their coatings.
The Correct Method
- Rinse both lenses first under lukewarm running water. This is the most important step because it helps remove dust and fine particles that could scratch the lens surface during wiping.
- Put a few drops of a mild dishwashing liquid on each lens and gently rub both sides with your fingertips.
- Rinse the glasses thoroughly, including the nose pads and hinges, where skin oils and dust can accumulate.
- Shake off excess water, then dry the glasses with a clean microfiber cloth using gentle pressure.
What You Should Never Use
- Your shirt, tie, or any item of clothing. Fabric can trap dust and fine particles, and rubbing the lens may drag those particles across the surface and increase the risk of scratches.
- Paper tissues or kitchen towels. They may contain coarse fibers that can scratch the lens surface or its coatings.
- Glass cleaner, acetone, vinegar, or any cleaner that is not specifically designed for lenses. Some of these substances may damage lens coatings, especially anti-reflective and water-repellent coatings.
- Your breath or saliva. Saliva can leave a film on the lens, and wiping a dry lens may drag dust across its surface and increase the risk of scratching.
Can Scratches Be Removed?
No. Some home remedies commonly found online, such as toothpaste, baking soda, car wax, and metal polish, work by further abrading the lens surface and may leave it more cloudy than before.
On coated lenses, these substances may also remove part of the coating and leave a cloudy area that is worse than the original scratch.
A scratched lens should be replaced rather than repaired.
Habits That Extend the Life of Your Frames
- Remove your glasses with both hands. Taking them off with one hand can gradually twist the frame and cause it to lose its proper alignment.
- Place them with the lenses facing upward, or preferably keep them in their case. Placing them face down on a hard surface can scratch the lenses, especially around the center.
- Never leave them inside a parked car. High temperatures inside the car can affect the frame material and damage lens coatings.
- Do not place them on top of your head. This can gradually stretch the temples and make them wider than they should be for your face.
- Wash your microfiber cloth regularly. A cloth covered with accumulated skin oils and dust will not clean the lenses effectively.
- Have your glasses checked and adjusted once or twice a year. It only takes a few minutes and can be done free of charge at any branch. Regular adjustment helps prevent frame looseness, slipping, and loss of proper lens alignment.
Dust and Why It Matters More Here
Airborne dust can contain fine mineral particles, including silica, and some of these particles can be harder than certain lens coatings.
That is why rinsing with water first is so important. Wiping a dry lens can drag dust particles across the surface and increase the risk of scratching.
If your glasses are exposed to dust every day, rinse them regularly and carry their case with you instead of leaving them exposed.
Loose hinges, a bent bridge or worn nose pads — most of these are a five-minute fix.

What is the best way to clean glasses?

Rinsing first is the most important step because it removes the dust and fine particles that could scratch the lens.
What should I never use to clean my glasses?
Avoid clothing, paper tissues and kitchen towels, which can drag dust across the lens or scratch it with coarse fibers. Avoid glass cleaner, acetone, vinegar or any cleaner not designed for lenses, as they may damage anti-reflective and water-repellent coatings. Do not use your breath or saliva either, since saliva leaves a film on the lens.
How do I remove scratches from my glasses?
Scratches cannot be removed. Home remedies such as toothpaste, baking soda, car wax and metal polish abrade the lens surface further and may leave it cloudier than before. On coated lenses they can also remove part of the coating. A scratched lens should be replaced rather than repaired.
How often should glasses be adjusted?
Once or twice a year. It only takes a few minutes and can be done free of charge at any branch. Regular adjustment helps prevent frame looseness, slipping, and loss of proper lens alignment.
