Good glasses care protects clear vision, preserves lens coatings and helps the frame keep its shape. Most damage happens through ordinary habits: wiping dusty lenses while dry, leaving glasses unprotected in a bag, exposing them to heat or placing them lens-down. A simple daily routine can prevent many avoidable scratches and adjustments.
How to clean your glasses properly
- Wash and dry your hands so they are free from grease, lotion and grit.
- Rinse the glasses under lukewarm water to remove loose particles. Avoid hot water, which may affect some lens coatings or frame materials.
- Apply a small amount of lotion-free, mild dishwashing liquid if the lens supplier permits it.
- Gently clean both lens surfaces, the frame front, bridge, nose pads and temples.
- Rinse thoroughly so no soap remains.
- Dry with a clean, soft microfibre cloth intended for optical lenses.
For cleaning away from home, use a lens-safe spray or individually packaged optical wipe according to its instructions. The ZEISS lens-care guide similarly recommends avoiding tissues and clothing, which can carry particles that produce fine scratches.
What not to use on coated lenses
- Shirt sleeves, paper towels, facial tissues or rough household cloths
- Window cleaner, bleach, ammonia or strong household chemicals
- Saliva or products not intended for optical lenses
- Hot water, hair dryers or direct heater air
- Dry rubbing when dust or grit is visible
Lens coatings vary. If your optician or lens manufacturer supplied different care instructions, follow those instructions.
Store glasses safely
Use a clean, hard protective case when the glasses are not being worn. Fold the temples carefully and place the glasses in the case rather than loose in a pocket, handbag or vehicle console. If a case is temporarily unavailable, set the glasses on their folded arms—not on the lens surfaces.
Protect glasses from heat and pressure
Do not leave glasses on a hot dashboard, near a stove or exposed to direct heat. Avoid wearing ordinary glasses on top of your head because this can spread the temples and transfer hair products to the lenses. Never place heavy objects on a glasses case or carry an unprotected frame in a back pocket.
Maintain the frame and hinges
Open and close both temples with two hands where possible. Check periodically for loose screws, worn nose pads or uneven temples. A trained optician can tighten, align and adjust the frame using tools and methods suited to its material. Rimless and semi-rimless designs require especially careful handling; browse rimless glasses only after considering your maintenance preferences.
Daily glasses-care checklist
- Rinse away grit before wiping.
- Use only a clean optical microfibre cloth.
- Keep the case clean and dry.
- Store glasses away from heat.
- Book an adjustment if the frame becomes loose or uneven.
- Replace lenses when scratches interfere with vision.
Frequently asked questions
How often should I clean my glasses?
Clean them whenever fingerprints, dust or residue affect clarity. Gentle cleaning is safer than allowing heavy buildup and then rubbing aggressively.
Can I wash the microfibre cloth?
Usually yes, using mild detergent without fabric softener, but follow the cloth supplier’s instructions and let it dry completely.
Should I keep old glasses?
A previous pair can be useful as an emergency backup if the prescription remains serviceable. Keep it clean and protected in a labelled case.
Ready for another pair? Browse all glasses by shape and colour.
