What is anti reflection glass?
Anti-reflective glass has been optically coated on one or two sides to eliminate reflections and increase the light transmission. JNS anti-reflective glass reduces surface glare and increases substrate transmission and brightness, offering better contrast definition over a specific wavelength range.
Anti-reflective lenses are very worth it, especially if you deal with a lot of glare from digital or LED screens, as well as glare from oncoming headlights when driving at night on a road trip. They also help you see better, look better, and feel better than going without uncoated lenses.
Do anti-glare glasses really work? Yes. Anti-glare coating allows nearly 100 percent (99.5) of available light to reach your eyes, which virtually eliminates glare.
Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain and makes your eyeglasses look more attractive. These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses.
Anti-glare is typically visible to the human eye while anti-reflective coatings typically exhibit a soft blue/green hue when deposited and is essentially invisible to the human eye minus a soft color.
The intact anti glare glasses reduce the reflection of light and give you clearer vision through lenses, but peeling anti-glare coating can ruin your vision and style. The average life of an anti glare coating is two years, and after that, you have to change it with the new one.
Anti-glare treatment is especially to eliminate this viewing problem. Glasses with anti-reflective lens coating has the ability to diffuse the reflected light and enhance your viewing experience. When it comes to glare reduction, anti-glare is said to be more pocket-friendly than the anti-reflective coating.
Lens material
Glass lenses provide the best vision but can damage the eyes if they break. Plastic lenses, though sturdier, have a tendency to scratch easily. Polycarbonate lenses are often the best since they are shatter-resistant and will not get scratches if they have an additional scratch-resistant coating.
Can computer glasses be worn all the time? It's common for people to want to wear their computer/blue light blocking glasses for protection and style. If your eyes don't need other prescription eyeglasses or contacts to see clearly, there is no harm in wearing your computer glasses all the time.
How do I know if I have it? Checking whether your glasses have an anti-reflective coating on them or not is relatively simple. When you hold your glasses, tilt them this way and that and look for glare. What you will see if you have an anti-reflective coating is a bit of glare, but mostly a greenish and pinkish color.
What are the disadvantages of anti-reflective coating?
1) The thin layer of anti-reflective coating on the lenses can get scratched or worn down over time, which makes it harder for you to see clearly and, in turn, affects your vision. 2) They don't prevent all glare and light from reaching your eyes, so it may cause you to have eye strain or headaches.
AR coatings protect your glasses against scratches and smudges, resulting in lenses that last longer. This also means you'll be replacing your lenses less frequently, which can help save you money.
Adding an anti-glare, or anti-reflective (AR), coating to your eyeglasses can allow more light in and also cut down on glare. Both of these things can improve night vision and improve vision for driving at night.
Anti reflective coatings are applied to all sorts of ophthalmic substrates (various plastics and glass materials), but the process and machinery required to reproduce these with any sort of uniformity time after time is where the cost comes from.

However, because it is a very thin layer applied to the lens's front and back surface, it can get easily scratched, degrading its optical properties. However, there is no way to repair the anti-reflective coating. So, you can choose to replace your glasses lenses or try to remove the damaged anti-reflective coating.

Why do my glasses have a green tint?
There is much less light reflected from the lenses and the colour of the lenses by reflected light is changed again. Such coatings produced at an opticians usually have a very faint residual colour which is usually green or blue and that is probably the reason for the colouration of your lenses.
