Before diving into the question, How long does anti-glare coating last? We should be aware of what it is first. It is a special cover for glasses to reduce their reflection of light.
Not every glass contains it due to its price. You have to pay much more money to buy anti-reflective glasses compared to ordinary ones. So, should you buy one? Read on to see if it's worth buying.
Does Anti-Glare Coating Wear Off?
Does anti-glare coating wear off? Well, that must be the first issue popping in your head, especially when it costs more than the normal glasses. The answer to that is yes. It does wear off eventually. Its wearing off will impact the glasses' appearance and decrease the possibility of reflecting light.
Yet, the anti-glare covering doesn't just tear off itself. It is mainly because of the way of using it. The more carefully you handle them, the longer the coating will last.
For example, many people usually wear them and put them back in their bags without any protection after use. The lenses will smack into other stuff inside, such as keys, pens, lipsticks, causing scratches. Another reason that damages the lenses is using unsuitable cleaning materials regularly.
Once it starts to peel off, you can't do anything to stop it but replace a new one or remove the covering completely from the lenses.
How Long Does Anti-Reflective Coating Last?
We can't tell the exact answer of how long does anti-glare coating lasts but it usually has a lifespan of 2 years on average. This period could be shorter or longer. It depends on how you use and protect them from external factors.
A careful treatment will lengthen the covering lifespan even for years, while rough handling will lead to the opposite. The anti-reflective covering is softer than the lenses underneath. That's why it demands proper care to keep your glasses in good condition.
If you already own a pair of anti-reflective glasses or are going to have ones, take these notes to keep it last as long as possible:
- Always clean your lenses with a microfiber cloth: Do not use rough materials to clean lenses. Cleaning it with the wrong materials will cause scratches on the lens's surface.
Harsh chemicals are not recommended since their components can quickly peel off the anti-reflective covering if used several times.
- Always keep the glasses inside a plastic or glass case when you are not wearing them: Constantly exposed to high temperatures will damage the anti-glare covering. We can't avoid it away from the heat produced from sunlight while wearing them.
But when you're not, you can protect them by leaving them in a case. Also, do not clean your lenses at extreme temperatures.
- Other tips: Buy anti-reflective glasses from a reputable brand, including a guarantee card. Especially do not clean when your lenses are dry. Touching the dry lenses with a dry cloth will highly scratch the surface. Doing that under running water is much preferred.
If you don't have any microfiber at home, an old cotton t-shirt through many would be fine since it's been worn out after multiple times of washing.
Is An Anti-Reflective Coating Necessary For Glass?
Whether an anti-reflective coating is necessary or not depends on the particular needs. Yet, we can't deny the benefits it brings out for the eyes.
The most visual benefit to mention is to create a better experience than normal ones, with clearer and more natural vision as it can reduce reflection from light. This feature performs extremely well when being under the sunlight or driving at night.
Also, the anti-glare lenses will comfort and protect your eyes from harmful rays of electronic devices. People who have to work with laptops or smartphones for hours should consider this advantage to spend their money.
Moreover, the lifespan of your glasses can be longer since this coating is capable of keeping your lenses from scratch. Your glasses need an anti-reflective coating when their benefits meet your demands.
If you're one of those who frequently drive at night, are exposed to sunlight directly, or use computers/smartphones for hours, you should equip your lenses with an anti-reflective covering.
Conclusion
How long does anti-glare coating last? As we said, it's usually two years, but that much depends on how you use it. Yet, glasses with an anti-glare covering are more expensive than those without one. Are they worth buying? The answer is a big Yes.
The advantages that the anti-reflective feature provides are way more worthy than the cost if you always keep it in good condition with proper care.
