How to Care for Your Sunglasses: The Complete Maintenance Guide

Most people don’t think much about how they care for their sunglasses — until they notice the scratches, the loose hinge, or the lens coating that’s started to peel. A quality pair of sunglasses, properly maintained, can last five to ten years. The same pair, poorly treated, might not survive two summers.

This guide covers everything: daily care, cleaning, storage, travel, and how to fix minor issues before they become expensive ones.

The Biggest Mistakes People Make

Before getting into best practices, here are the habits that destroy sunglasses fastest:

• Wiping lenses with clothing: T-shirts, shirts, and jacket fabrics contain fibres that scratch lens coatings even when they feel soft. Over time this causes permanent surface damage that no cleaning can fix.
• Leaving on dashboards: The interior of a car in direct sunlight can exceed 70°C. This temperature warps acetate frames, degrades lens coatings, and weakens adhesives in temple tips.
• Storing in bags without a case: Keys, coins, pens, and phone corners scratch lenses and bend frames. Every. Time.
• Pulling frames off one-handed: One-handed removal puts asymmetric stress on hinges, gradually loosening one side faster than the other and warping the frame over time.
• Using household cleaners on lenses: Glass cleaners, alcohol wipes, and general-purpose sprays strip anti-reflective and UV coatings from lenses.

How to Clean Sunglasses Correctly

Daily Cleaning

1. Rinse lenses under lukewarm water to remove dust and grit. Wiping without rinsing first drags particles across the lens surface and causes micro-scratches.
2. Apply a small drop of mild dishwashing liquid (not antibacterial, not concentrated) to each lens.
3. Gently rub both sides of the lens with clean fingertips. Clean the frame, nose pads, and hinges too.
4. Rinse thoroughly under lukewarm water until all soap is removed.
5. Dry gently with a clean, lint-free microfibre cloth. Pat rather than rub.

What to Avoid When Cleaning

• Hot water: Weakens lens coatings and can warp acetate frames.
• Paper towels or tissue: Wood fibre in paper products is abrasive on lens surfaces.
• Saliva: Common habit, genuinely not effective at cleaning, and introduces bacteria.
• Alcohol-based cleaners: Damage UV and anti-reflective coatings over time.
• Ultrasonic cleaners: Can loosen lens adhesives and damage coatings in certain frame types.

Microfibre Cloths: What You Need to Know

A microfibre cloth is only effective when clean. A cloth that’s been sitting at the bottom of a bag picks up skin oils, dust, and particles that then get transferred back to the lens during cleaning. Wash your microfibre cloth regularly — hand wash in mild soap, air dry. Replace it every few months of daily use.

Proper Storage

At home: Use the hard case that came with your frames, or invest in one separately. Keep it in a consistent, accessible spot so you actually use it. Temperature-stable environments are best — avoid windowsills and spots that receive direct sunlight.

On the go: Always in the case when not on your face. Never placed lens-down on a surface. Never tucked into a pocket or bag open. The few seconds it takes to case your sunglasses is worth months of extended lens life.

Travel: Hard case inside your bag, away from keys and coins. If travelling with multiple pairs, individual microfibre pouches with a shared hard case is a practical approach.

Hinge Maintenance

Hinges are the most common failure point in sunglasses. The screws that hold hinges together are tiny and loosen with regular use.

• Check hinge screws every few months. A glasses repair kit (available at most pharmacies) includes a micro-screwdriver to tighten them. Takes 30 seconds.
• If a hinge feels loose or a lens is slightly misaligned, don’t force it. Take the frame to an optician who can adjust it without damaging the frame.
• Spring hinges are more durable for daily use but harder to repair if they fail. Barrel hinges are simpler to maintain.

Handling After Beach or Pool Use

Salt water and chlorine are both damaging to lens coatings and metal frame components over time. After any sea or pool exposure:

1. Rinse immediately under fresh water to remove salt or chlorine residue.
2. Dry with a microfibre cloth.
3. Don’t leave wet frames in a closed case — allow to air dry first.

When to Replace vs. Repair

• Loose hinge screw: Repair. Costs almost nothing, takes minutes.
• Bent frame: An optician can often straighten metal frames. Acetate requires heat treatment — take it to a professional rather than attempting it yourself.
• Deep lens scratches: Lenses with deep scratches cannot be polished out at home. Replacement lenses from the original brand (if available) or a lens replacement service is the answer.
• Peeling lens coating: Replace the lenses. A peeling coating means the UV protection layer is compromised.
• Cracked frame: If structural integrity is affected, replace the frame. A cracked acetate frame near the hinge is a break waiting to happen.

Invest in Frames Worth Maintaining

Proper care only makes sense when the frames are worth caring for. A quality pair of SOLEYA sunglasses with UV400 lenses, premium acetate or metal construction, and well-engineered hinges is worth the attention. Browse the full collection here.
