A good pair of glasses is an investment. How you care for them determines how long they stay in top condition.
Here’s what you need to know — no special products required.
Daily Cleaning: Do It Right
Most lens scratches come from improper cleaning, not accidents.
The Right Way
- Rinse first. Run your glasses under cold water to remove dust and debris. This prevents scratching when you wipe.
- Add a drop of mild dish soap. Use a small drop on each lens. Rub gently with your fingers.
- Rinse again. Make sure all soap is gone.
- Shake off excess water. A quick shake removes most of the droplets.
- Dry with a clean microfiber cloth. Use gentle, circular motions. Don’t use your shirt, tissue, or paper towel — these can scratch lenses.
What NOT to Use
- Paper towels, napkins, tissues — Wood fibers in paper products scratch lenses
- Clothing, especially dry fabric — Can contain dust and grit
- Window cleaner, bleach, or ammonia — These strip anti-reflective and UV coatings
- Hot water — Can damage lens coatings
Storage: Where Glasses Spend Most of Their Time
How you store your glasses when you’re not wearing them matters more than you think.
Always use a hard case. When your glasses aren’t on your face, they should be in a case. This protects them from scratches, crushing, and accidental drops.
Never put them lens-down. If you must set them down temporarily (no case available), place them lens-up. Lens-down = guaranteed scratches.
Don’t leave them in the car. Heat warps frames (especially acetate) and damages lens coatings. A car dashboard in summer can reach 80°C+ — enough to permanently deform frames.
Avoid leaving them on your head. Stretching the temples constantly wears out the hinges over time.
Adjustments: When to Get Help
Frames shift over time. If your glasses feel loose, slide down your nose, or sit unevenly, they need adjustment.
Titanium frames are relatively easy to adjust. A professional optician can bend the temples and nose pads for a precise fit.
Acetate frames need to be heated before adjusting. Don’t try to bend them cold — they’ll crack.
DIY is not recommended unless you know what you’re doing. Over-adjusting can weaken the frame or cause permanent damage.
Most opticians will adjust your frames for free or for a small fee, even if you didn’t buy the glasses from them.
Common Problems & Fixes
Frames Feel Loose
The temples (arms) have likely spread outward. Gently push them inward. If they keep loosening, get them professionally adjusted.
Nose Pads Leave Red Marks
They may be too tight or uneven. Have them adjusted by a professional. For titanium frames, adjustable nose pads are a standard feature.
Lens Coating Peeling
This usually happens from exposure to heat or harsh chemicals. Unfortunately, once a coating starts peeling, it can’t be repaired — the lenses need to be replaced.
Prevention: Keep glasses away from hot environments and never use chemical cleaners.
Screws Coming Loose
This happens. Keep a small eyeglass screwdriver handy for quick tightening. Most frames use standard-sized screws available at optician shops.
How Often Should You Replace Your Glasses?
Frames: A well-made titanium frame can last 3-5 years or more with proper care. Acetate frames typically last 2-4 years.
Lenses: Replace every 1-2 years, or whenever your prescription changes. Even if your prescription hasn’t changed, lens coatings degrade over time.
Signs it’s time for new lenses:
- Scratches that affect vision
- Peeling or flaking coatings
- Yellowing of lenses
- Your eyes feel strained more often

Final Thought
Glasses care isn’t complicated. The two things that matter most: rinse before you wipe, and always store in a case. Do those consistently, and your frames will last years longer.
