The Complete Guide to Cleaning and Caring for Your Glasses
The right way to clean glasses: rinse off grit first, use a lens-safe cleaner (not tap water alone, tissues, or your shirt), wipe with a clean microfibre cloth, and let anti-fog protection do the rest before it fogs up on you. Get those four things right and you avoid the two most common causes of ruined lenses: scratches from the wrong cloth, and stripped coatings from the wrong cleaner. Below is the full rundown, covering glasses, sunglasses, camera lenses, visors, and the screens you touch all day too.

How Do I Clean My Glasses Without Scratching Them?
Eight steps, in order. Skip the shortcuts and this takes about 30 seconds. All you need is a lens-safe spray cleaner and a clean microfibre cloth.
- Rinse your hands first. Any lotion or oil on your fingers ends up on your lenses.
- Rinse the glasses under lukewarm water if there's dust or grit on them. Wiping dry lenses with debris still on them is how you get micro-scratches, and it's the single most common mistake people make.
- Spray a lens-safe cleaner directly onto each lens. Two pumps is plenty.
- Wipe with a clean, dry microfibre cloth using light, circular pressure. Don't press hard. Let the cloth do the work.
- Get the frame and nose pads too. Oil and skin build-up there causes slipping and irritation over time.
- Check both sides against the light for streaks before you call it done.
- If your cloth has been living in a pocket or bag, wash it first (see the cloth care section below). A dirty cloth just moves grime around instead of lifting it.
- Store the glasses in a case, not lens-down on a table.

What Should I Never Use to Clean My Glasses?
Most damaged lenses aren't the result of an accident. They're the result of a habit. Here's what to drop.
| Safe to use | Avoid |
|---|---|
| A dedicated lens spray, or a drop of lotion-free dish soap and water | Household glass or surface cleaner (often contains ammonia, which attacks coatings) |
| A clean, dry microfibre cloth | Tissues, paper towel or napkins (wood fibres are abrasive at a microscopic level) |
| Lukewarm water to rinse off grit before wiping | Your shirt hem or sleeve (unknown fabric, unknown grit, guaranteed smudge) |
| A cleaner labelled safe for coated or anti-reflective lenses | Saliva (bacteria aside, it just doesn't clean) |
| Hands-off drying: a clean cloth, patted rather than rubbed if lenses are very dirty | Hot water or a hairdryer (heat can warp frames and degrade coatings) |
Optometry guides consistently flag the same offenders: paper products, ammonia-based cleaners and dry wiping. All About Vision's cleaning guide covers the same ground if you want a second source. The short version: if it's not designed for lenses, it's a gamble.
How Do I Clean Anti-Reflective or Coated Lenses Safely?
Coated lenses (anti-reflective, blue light, scratch-resistant) are a thinner, more delicate layer sitting on top of the glass or polycarbonate. That's what makes them glare-free and scratch-resistant when new, and it's also what makes them the first thing to fail if you clean them wrong.
Ammonia and harsh solvents cloud or peel a coating over months of use, even if nothing looks wrong after one clean. Check the label says "safe for coated lenses" before it goes anywhere near an AR-treated pair.
Luma's anti-fog spray is formulated without ammonia or silicones and is safe on anti-reflective, treated and multi-coated lenses. For the full breakdown of what damages coatings and what doesn't, read How to Clean Anti-Reflective Coated Glasses (Without Damaging Them).
How Do I Stop My Glasses Fogging Up?
Fogging happens when warm, moist air hits a cooler lens and condenses into tiny droplets that scatter light. Masks, cold mornings, exercise, and stepping from air conditioning into humidity are the usual triggers.
Wiping the fog away doesn't fix the cause, it just buys you a minute. Anti-fog spray does, because it leaves behind a hydrophilic film that spreads condensation into a thin, invisible layer instead of light-scattering droplets. Luma's spray uses PVP K30, the same type of film-forming polymer used in medical-grade optical coatings, for hours of fog-free wear on a single application.
For the full explanation and mask-specific fixes, read Why Do My Glasses Fog Up? and How to Stop Glasses Fogging with a Mask.
How Do I Clean My Phone, Laptop and Other Screens the Same Way?
Same rules, different surface. Phone, laptop and tablet screens pick up the same fingerprint oil and dust as your lenses, and the same bad habits (tissues, shirt hems, spraying cleaner directly onto the screen) cause the same problems: streaking and, on some coated displays, a worn-away oleophobic layer over time.
Spray the cloth, not the screen, and wipe in one direction rather than scrubbing in circles on electronics with visible pixels.
Luma Screen Mist Cleaner 2-in-1 is built for phones, laptops, tablets and TVs, $15.00. One spritz lifts fingerprints and dust without streaking.
How Do I Look After Sunglasses, Camera Lenses and Visors?
The core method doesn't change, but a few surfaces deserve a specific mention:
- Sunglasses: tinted and polarised lenses are cleaned exactly like clear ones. Watch for grit from sand or dust, that's the main scratch risk outdoors.
- Camera and DSLR lenses: use a blower or soft brush first to remove dust before any cloth touches the glass, then follow the same spray-and-wipe process.
- Motorcycle and scooter visors: bugs, road grime and fog all hit at once. See How to Clean a Motorcycle Visor (Without Scratching It) if that's your main use case.
Deluxe Anti-Fog Visor & Bug Optics Kit is built for bugs, grime and fog on a visor, not just glasses, $29.95.
How Do I Care for My Microfibre Cloth?
A dirty microfibre cloth doesn't clean, it redistributes. Every bit of grit trapped in the fibres is a scratch risk the next time you use it. Wash it at 30°C, by hand or on a gentle machine cycle, with no fabric softener (it coats the fibres and kills the cleaning performance). Air dry or tumble on low heat, skip the bleach, and it'll keep working for hundreds of cleans.
How Should I Store My Glasses to Avoid Scratches?
Storage causes more scratches than cleaning does. Three habits fix most of it:
- Use a case. Every time. A bag or pocket without one is a scratch waiting to happen.
- Never set glasses down lens-side on a table, counter or car dash.
- Take them off with both hands. One-handed removal flexes the frame and loosens the hinges over time.
How Often Should I Clean My Glasses and Reapply Anti-Fog Spray?
Clean your lenses daily if you can, it takes 30 seconds. Anti-fog protection lasts hours per application rather than days, so reapply at the start of each session where fogging is a problem: before a ride, before a workout, before you put a mask on for a shift. For a full breakdown of how to pick between spray, wipes and gel, read How to Choose an Anti-Fog Spray.
3-Pack Deluxe Anti-Fog Lens & Screen Kit, $45.95. Three 100ml bottles so you're never caught out mid-fog, works out cheaper per use than restocking one at a time.
Frequently Asked Questions
Can I clean my glasses with just water?
Water alone rinses off dust and loose grit, which is a good first step, but it won't shift oil or fingerprints on its own. Follow it with a lens-safe spray for a proper clean.
Is it safe to use tissues or paper towel on my glasses?
No. Paper products are made from wood fibres that are abrasive at a microscopic level. They'll leave fine scratches over repeated use, even if you can't see them straight away.
How do I know if my lens coating is being damaged?
Early signs are a hazy or cloudy patch that won't wipe away, tiny rainbow-like streaks, or the coating starting to peel at the edges. If you see any of that, stop using whatever cleaner you were using and switch to one labelled safe for coated lenses.
Does anti-fog spray work on anti-reflective coated lenses?
Yes, as long as the formula is labelled safe for coated lenses. Luma's spray is formulated without ammonia or silicones specifically so it can be used on AR and multi-coated lenses.
How often should I replace my microfibre cloth?
A well-cared-for cloth (washed regularly, no fabric softener) can last a long time. Replace it once it feels stiff, has visible snags, or stops picking up smudges the way it used to.
Can I use the same cleaner on my glasses and my phone screen?
A cleaner formulated for both is fine to use on either. Just check the label, some screen-specific formulas are too harsh for lens coatings and vice versa.
