Why your glasses age so fast
You spent 400 euros on your new glasses. Beautiful design, perfect lenses, anti-reflective coating included. A year later, the same glasses stare back at you from the mirror, cloudy and scratched.
What happened?
Spoiler alert: It wasn't the glasses. It was the way you cleaned them.
The problem lies in the coating.
Modern eyeglass lenses are coated with several ultra-thin layers. The most well-known is the anti-reflective coating—it ensures that no light is reflected back from your lenses and that the person opposite you sees your eyes, not their own reflection.
This coating is only 200 to 300 nanometers thick. For comparison, a human hair is around 70,000 nanometers thick. So you're cleaning a surface that's more delicate than you probably think.
That really makes your glasses look old.
1. Shirt, T-shirt and handkerchief
The first thing most people instinctively do when their glasses get dirty is wipe them on the nearest cloth. Convenient, quick, disastrous. Even soft cotton fabric has a rough, fibrous surface under a microscope. Combined with dirt particles on the lenses—and on the cloth—this acts like sandpaper on your lens coating. Invisible. But accumulated over months, the damage is real.
2. Alcohol, household cleaners, etc.
Many people reach for disinfectant, glass cleaner, or dish soap. Sounds logical. But it's usually wrong. Many of these products contain solvents that dissolve the coating. Once might sound harmless. After the fiftieth time, the coating starts to peel off—that iridescent, patchy look you might already be familiar with.
3. Heat
Summer heat in the car, hot water while washing dishes, the sauna: heat causes the lens to expand slightly. The coating expands with it—but not always at the same rate. Over time, tiny hairline cracks develop in the coating's structure. You see the result as a fine, spiderweb-like pattern on your lenses.
4. Cosmetics and fingerprints
Sunscreen, foundation, hair gel—all of these end up on your lenses sooner or later. These substances are chemically aggressive enough to damage coatings. Fingerprints sound harmless, but they are mixtures of grease and salt that react slowly on the surface if they are not regularly removed.
What this means for your vision
Damaged lens coating isn't just a cosmetic problem. Cloudy or scratched lenses scatter light instead of focusing it. Contrasts appear flatter, glare increases, and your eyes have to work harder. Those with sensitive eyes may notice this as fatigue or mild headaches at the end of a long day.
And then there's hygiene: On average, eyeglass lenses are lifted or touched seven to eight times a day. The frame and nose pads are a direct contact point with your skin. If they aren't cleaned, bacteria, sebum, and residue from skincare products accumulate there—an underestimated issue for anyone struggling with blemishes.
How to really protect your glasses
The simple answer: clean properly, regularly.
Specifically, this means: no shirt, no handkerchief, no kitchen roll. Instead, a special cleaning solution formulated for eyeglass lenses and their coatings — and a high-quality microfiber cloth that is free of dirt particles.
That's precisely why we developed the EYESHAKER. As passionate opticians with over 25 years of experience, we wanted to create a cleaning system that truly works—for lenses, frames, nose pads, and all those areas a cloth can't reach. Completely electricity-free, completely uncompromising.
Your glasses have done a lot for you. Time to give something back.
Shake it.
