Why does the coating on glasses wear off

| 25.10.2020

One of the most essential senses mother nature has bestowed upon us is the sense of vision. It is the marvel that allows us to view and witness other marvels.


But as great as they may be, they still require a lot of care to be taken of them as they are indeed a very sensitive part of our bodies.


Modern technology has allowed us to still be able to use our eyes to the best of their abilities, even after we have damaged them from poor usage and bad ocular health hygiene.

The simplest of these accessories are the eyeglasses. These specifically designed glasses for vision correction can now be customized to our exact needs.


Some of the most important of these customizations are the coatings we can get to further improve our vision and the aesthetic outlook of these glasses.


Lenses are constructed according to the customer’s needs and then the requested coatings are layered over them.


Since these coatings are just in the form of films over the actual lenses, they have a much higher chance of coming off during the lens cleaning processes.


How long does anti-reflective coating last?


The answer to this question can vary from person to person. What really matters is the way you handle your glasses.


If you use a proper glasses cleaning soft, silky material for wiping your glasses clean, chances are that the coatings on your glasses will last you a much longer time than someone who uses glasses with bad cleaning habits.


If a generalization is to be made, then with proper cleaning ethics, an anti-reflective coating on glasses should last you about two years.


Keep in mind that this figure is for someone who uses their glasses in a good manner and does not use harsh or rough material to scrape their glasses clean.


On the other hand, if you use your glasses in a more lax manner, using rough and coarse materials for cleaning purposes and not taking care of scratches, the anti-reflective coating on your glasses may only last you a few months at best.


Do I need an anti-reflective coating?


If you are a person who spends a lot of their time staring at digital screens or going and working outside in the sun or has to drive at night or works in an environment that has a lot of fluorescent bulbs and lightings or has a glasses number of +/- 4.00 or higher, then you should definitely opt for anti-reflective coating over your glasses.


The anti-reflective coating prevents layers and sheets of glare from forming right in front of your eyes when you are wearing your glasses.


This feature is super important for your ocular health. The amount of stress reflection and glare puts on your eyes can be too much for your eyes to handle. This can also make your vision go into further deterioration over time.


A lot of people complain of their anti-glare coating coming off glasses. This is a common occurrence for people who are somewhat irresponsible with their glasses.


One of the most important points to consider while making a choice for lens coatings is to determine how much blue light you get exposed to within a day.


Blue light is the shortest wavelength light of the visible spectrum. It is emitted by the Sun in the form of UV radiations as well as by our digital screens including our smartphones, laptops, LEDs, televisions, and tablets.


This blue light is extremely harmful to our eyes as they can easily penetrate into the deepest layers of our eyes and into our retina and damage the retinal cells.


This damage can cause age-related macular degeneration among other conditions, severely damaging your vision.


So, if you work in environments that include a lot of screen time or even Sun exposure, you should definitely consider including a blue light coating into your glasses.



Poor management of our glasses can do them a lot of harm. To protect the coatings on your glasses, we recommend you always use a soft and smooth piece of cloth to clean your glasses. It is the only way to protect the coatings on your glasses.
