How to Care for Your Eyeglasses: a Comprehensive Guide for Longevity and Clarity

Your eyeglasses are more than just a medical device; they are a significant investment in your quality of life. Whether you wear them for reading, driving, or all-day vision correction, the condition of your lenses and frames directly impacts how well you see the world.

Despite their importance, many of us unintentionally damage our eyewear through improper cleaning habits or storage mistakes. A quick wipe with a shirt tail or leaving them on the car dashboard might seem harmless in the moment, but these small actions accumulate, leading to scratched coatings, warped frames, and reduced visual acuity.

At Durham Vision Care, we want to help you maintain your eyewear so it serves you well until your next prescription update. This guide covers the essential protocols for cleaning, handling, and protecting your glasses, specifically tailored to our local environment here in Ontario.

The Daily Cleaning Ritual

The most effective way to keep your vision clear is to establish a routine. Lenses accumulate dust, oils from your skin, and environmental debris throughout the day. Cleaning them properly prevents the buildup of grime that can degrade lens coatings over time.

The Step-by-Step Method

For the safest clean, we recommend a wet cleaning method. Dry wiping, even with a soft cloth, can drag microscopic dust particles across the lens surface, creating fine scratches.

1. Wash Your Hands: Before touching your glasses, wash your hands thoroughly with soap and water. Ensure you use lotion-free soap, as moisturizing ingredients can transfer to the lenses and cause smearing.
2. Rinse with Lukewarm Water: Hold your glasses under a gentle stream of lukewarm tap water. This step is crucial as it rinses away dust and grit that could scratch the lens during the washing process. Avoid hot water, which can damage specialized lens coatings.
3. Apply a Drop of Soap: Place a tiny drop of lotion-free dishwashing liquid on each lens. You only need a small amount.
4. Gently Rub: Using your fingertips, gently rub the soap over both sides of the lenses, the nose pads, and the temples (arms). This removes skin oils and bacteria.
5. Rinse Thoroughly: Rinse the glasses again to remove all soap traces.
6. Shake and Dry: Gently shake off excess water. Dry the lenses and frame with a clean, lint-free microfiber cloth.

The Importance of Microfiber

Cotton towels, tissues, and paper towels are wood-based products. While they feel soft to the skin, they contain coarse fibres that act like sandpaper on optical lenses. We always recommend using a dedicated microfiber cloth designed for eyewear. These cloths trap oils and dust without scratching the surface.

If you are on the go and do not have access to a sink, use a specific lens cleaning spray and your microfiber cloth. Ensure the spray is approved for coated lenses.

Common Habits That Damage Eyewear

Even with good intentions, certain habits can shorten the lifespan of your glasses. Avoiding these common pitfalls is just as important as knowing how to clean them.

The “Shirt Clean”

It is tempting to use the hem of a t-shirt or a scarf to wipe away a smudge. However, clothing fabrics often harbour dust, dirt, or fabric softeners that can scratch lenses or leave a greasy residue.

Chemical Damage

Household glass cleaners (like those used for windows) often contain ammonia or bleach. These chemicals are too harsh for optical lenses. They can strip away anti-reflective or UV-protective coatings, leaving the lenses looking cloudy or crazed (a web of tiny cracks).

Similarly, products containing acetone (like nail polish remover) or high concentrations of alcohol can degrade the plastic of the frames and the lens surface.

The “Headband” Maneuver

Resting glasses on top of your head is a common convenience, but it distorts the frame. This stretches the temples outward, loosening the fit. Over time, the glasses may slide down your nose or fall off completely. Additionally, hair products like gel or hairspray can transfer to the lenses, damaging the coatings.

Understanding Lens Coatings

Modern eyeglass lenses are marvels of optical engineering, often featuring multiple layers of technology. Understanding what is on your lenses helps you care for them better.

Anti-Reflective (AR) Coatings

AR coatings improve vision by allowing more light to pass through the lens and reducing glare from screens and headlights. However, these coatings are sensitive to extreme heat and harsh chemicals. Using improper cleaners can cause the AR layer to peel or craze.

Blue Light and UV Protection

Many patients in Durham choose lenses with blue light filtration or UV protection. These treatments are integral to the lens structure or coating stack. To maintain their efficacy, avoid leaving glasses in direct sunlight when not in use, as intense UV exposure over long periods can sometimes yellow certain lens materials or degrade the frame.

The Ontario Factor: Weather and Your Glasses

Living in Oshawa and the Durham Region means dealing with a unique climate that affects eyewear. From humid summers to freezing winters, our local weather requires specific attention.

Thermal Shock

Moving from a freezing parking lot into a warm grocery store causes immediate expansion and contraction of frame materials. While high-quality frames are designed to withstand this, repeated extreme thermal shock can make plastic frames brittle over time.

The Hot Car Danger

In the summer, the interior of a car can reach temperatures far higher than the outside air. Leaving your glasses on the dashboard can cause the frames to warp and the lenses to delaminate (where the coatings separate from the lens). Always take your glasses with you.

Managing Fog

During our colder months, fogging is a frequent issue. When cold lenses meet warm breath or indoor air, condensation forms. While wiping is the immediate reaction, constant wiping increases the risk of scratching. We recommend asking about anti-fog lens treatments or using specific anti-fog sprays available at optical dispensaries.

Frame Hygiene and Skin Health

We often focus on the lenses, but the frame requires attention for hygiene reasons. Your glasses sit in constant contact with your face, specifically the bridge of your nose and behind your ears.

Bacterial Buildup

Research indicates that nose pads and ear clips are the most contaminated areas of eyeglasses. Sweat, makeup, and dead skin cells accumulate in the crevices of the frame, creating an environment for bacteria to grow. This can lead to skin irritation, acne, or contact dermatitis at the touch points.

Cleaning the Hardware

When you wash your lenses, take an extra moment to gently soap and rinse the nose pads and the temples. For intricate parts of the frame where dirt collects, you can occasionally use a soft-bristled toothbrush (dedicated only to this purpose) to gently dislodge debris from the hinges and nose pad arms.

Storage and Handling

Proper storage is the first line of defense against accidental damage.

The Case for Cases

When your glasses are not on your face, they should be in a case. A hard-shell case offers the highest level of protection against crushing or bending. Nearly one in three pairs of glasses sustains damage due to improper storage.

If you leave them on a nightstand, they are vulnerable to being knocked over, stepped on, or chewed by pets.

The “Lens Up” Rule

If you must set your glasses down without a case for a moment, always place them with the temples open and upside down (resting on the top of the frame rim) or folded with the lenses facing upward. Never place glasses lens-down on a surface, as this guarantees contact with potential abrasives.

The Role of Professional Maintenance

Even with diligent home care, eyeglasses require professional maintenance. The screws that hold the frame together can loosen with daily use, and nose pads can degrade over time due to skin oils.

Regular Adjustments

We recommend visiting an optician periodically to have your frames tightened and realigned. A proper fit ensures the optical center of the lens sits exactly where it should in front of your pupil, providing the clearest possible vision.

Comprehensive Eye Exams

Caring for your glasses is part of caring for your sight, but it does not replace the need for regular check-ups. In Ontario, OHIP covers annual comprehensive eye exams for children and youth aged 0-19 and seniors aged 65 and older. For adults aged 20-64, routine exams are vital for monitoring eye health and updating prescriptions.

Using glasses with an outdated prescription can lead to eye strain and headaches. When you come in for an exam, bring your current glasses. Your optometrist can assess the condition of the lenses and frames to ensure they are still providing adequate correction.

Summary

Taking care of your eyeglasses does not require expensive tools or hours of time. It simply requires a shift in habits. By avoiding harsh chemicals, using proper cloths, and storing them safely, you can extend the life of your eyewear significantly.

At Durham Vision Care, we are here to assist you with all your eyewear needs, from selecting the right frames to providing adjustments that ensure a comfortable fit.

Frequently Asked Questions

What is the absolute best way to clean my glasses?

The most effective method is to rinse them under lukewarm tap water to remove dust, apply a small drop of lotion-free dish soap, rub gently with your fingers, rinse thoroughly, and dry with a clean microfiber cloth. This removes oils and debris without scratching.

Can I use hot water to kill bacteria on my glasses?

No. You should avoid hot water. High temperatures can cause the coatings on your lenses (such as anti-reflective or UV coatings) to expand at a different rate than the lens material, leading to cracking or peeling (crazing). Lukewarm water and soap are sufficient for hygiene.

How do I get scratches out of my lenses?

Unfortunately, once a lens is scratched, it generally cannot be repaired. The “hacks” found online (like using toothpaste or baking soda) often make the problem worse by clouding the lens further. Scratches scatter light and can cause eye strain. If your lenses are scratched, visit your optician to discuss replacement options.

How often should I clean my glasses?

You should give your lenses a light cleaning daily to remove oils and dust. A more thorough cleaning of the frames, including the nose pads and ear pieces, should be done weekly to maintain hygiene and prevent skin issues.

Why do my glasses keep sliding down my nose?

This usually indicates that the frame is out of alignment or the nose pads need adjustment. It is a common issue that occurs with daily wear. Visit an optician for a professional adjustment; attempting to bend the frame yourself can result in breakage.
