Best ways to clean eyeglasses
As an optometrist with years of experience here in the Calgary area, I’m often surprised by how many people are unsure of the best way to clean their eyeglasses. It seems simple, but doing it wrong can actually damage your lenses, especially with modern coatings. This isn’t just about aesthetics – it's about maintaining clear vision and extending the life of your investment. Let's dive deep into everything you need to know.
What actually gets eyeglasses dirty?
It’s not just visible grime. A lot of what you’re seeing is a combination of:
- Oils: From your skin, makeup, hair products, and even the air (think cooking fumes). These are surprisingly sticky and attract dust.
- Dust & Debris: Airborne particles are constantly settling on your lenses.
- Water Spots: Hard water leaves mineral deposits that can be difficult to remove.
- Micro-scratches: While not "dirt", improper cleaning creates these. This is the biggest concern. Abrasive cloths or cleaners will slowly erode the surface of your lenses, creating a hazy appearance.
Modern lenses have increasingly complex coatings – anti-reflective, blue light blocking, scratch-resistant, etc. These are incredibly thin layers, and harsh chemicals or abrasive materials can break them down. Think of it like the coating on a smartphone screen; you wouldn’t use sandpaper on that, would you?
What should I use to clean my eyeglasses? (And what should I absolutely avoid?)
Let's start with the “do nots.” You’d be amazed what people try!
- Absolutely avoid: Paper towels, tissues, napkins, your shirt, dish soap, window cleaner, alcohol-based cleaners, and anything with lotion. These are all abrasive or contain chemicals that will damage coatings.
- Don’t use hot water: Extreme temperatures can also damage coatings. Lukewarm water is best.
Here’s what is recommended:
- Microfiber Cloth: This is your best friend. Invest in several – they’re inexpensive. Make sure they're truly designed for eyeglasses, not just a generic "microfiber" cloth. The weave matters. Launder them regularly (more on that below).
- Eyeglass Lens Cleaner: Specifically formulated lens cleaner is ideal. These are available at most optical stores and pharmacies. Avoid sprays with added fragrances or dyes.
- Lukewarm Water: For a quick clean, lukewarm water can often do the trick.
- Dish Soap (in a pinch): If you absolutely must use soap, use a single drop of mild, lotion-free dish soap diluted in lukewarm water. Rinse thoroughly. This is a last resort and should not be a daily practice.
Step-by-step cleaning guide
- Wash your hands: Sounds obvious, but essential! You don't want to transfer oils from your hands to your lenses.
- Rinse your eyeglasses: Hold them under a gentle stream of lukewarm water to remove loose dust and debris. This is important – removing particles before wiping prevents scratches.
- Apply lens cleaner (or soapy water): Spray a small amount of lens cleaner onto both sides of each lens. If using soapy water, dip your fingertips into the solution and gently apply.
- Gently wipe: Using a clean microfiber cloth, gently wipe the lenses in a circular motion. Avoid applying excessive pressure.
- Dry: Use a fresh, dry portion of the microfiber cloth to dry the lenses.
- Inspect: Hold your glasses up to the light to check for streaks or smudges. If needed, repeat the process.
How often should I clean my eyeglasses?
Ideally, daily. It doesn’t have to be a full cleaning every time – a quick rinse with water and a wipe with a microfiber cloth can often suffice. However, a thorough cleaning with lens cleaner should be done at least a few times a week, depending on your environment and lifestyle. If you work outdoors or in a dusty environment, you may need to clean them more frequently.
How do I care for my microfiber cloths?
Microfiber cloths need to be cleaned regularly to remain effective. Here’s how:
- Wash them separately: Don’t wash microfiber cloths with other laundry, as lint from other fabrics will cling to them and reduce their cleaning ability.
- Use mild detergent: Use a liquid detergent that is free of dyes, fragrances, and fabric softeners.
- Wash in lukewarm water: Avoid hot water.
- Air dry: Do not put microfiber cloths in the dryer. Heat can damage the fibers.
- Replace regularly: Even with proper care, microfiber cloths will eventually wear out. Replace them every few months.
Dealing with stubborn smudges and specific lens types
Sometimes, you encounter stubborn smudges that won’t come off with regular cleaning. Here are a few tips:
- For grease or oil: A very small amount of diluted dish soap (as mentioned above) can help.
- For sticky residue: Gently try to lift it off with a corner of a clean microfiber cloth. Avoid scrubbing.
- For anti-reflective coatings: These are particularly delicate. Always use lens cleaner specifically designed for anti-reflective lenses.
- For progressive lenses: Be extra careful when cleaning the different zones of progressive lenses. Avoid applying excessive pressure to any particular area.
What about pre-moistened lens wipes?
These can be convenient, especially when you're on the go. However, be cautious. Many contain alcohol or other harsh chemicals. Look for wipes specifically labeled as “safe for all lens coatings.” Check the ingredient list carefully. A good wipe is better than nothing, but a proper cleaning with lens cleaner and a microfiber cloth is always preferable.

Our climate here in Okotoks, with its dry winters and occasional dust storms, can be particularly hard on eyeglasses. Dust and road grime accumulate quickly.

Taking a few extra minutes each day to clean them properly will not only keep them looking their best but will also help you see your best for years to come.
