So many lens options to choose from.
When you’re buying new glasses, all these additional coatings seem like a bit of an up-sell.
But what is anti glare? And what does it do?
Anti glare or anti reflective is an additional lens coating designed to improve your clarity of vision. This coating increases the transmission of light through the lens whilst reducing the light reflecting off the front and rear lens-surfaces.
In other words, anti glare and anti reflective are the same thing. Sometimes you might hear them being called AG, AR or MAR for short.
And due to the way they work, they help you see more clearly by letting as much as 99.9% of the light through the lens, rather than it bouncing off. Because the more light that gets through your lens, the better you can see.
Sounds good right?
Notice the purple and green hues being reflected from these anti reflective lenses.
Anti glare coating contains multiple layers of very thin metal oxides with differing refractive indexes. This allows the lens to transmit more visible light which improves your visual acuity in different conditions, light or dark.
When you’re talking to someone, eye contact is an important social connection.
Because more light is transmitted through an anti glare lens, your eyes are more visible to people who’re talking to you. Uncoated lenses can yield harsh reflections across the surface of the lens which can inhibit eye contact.
Arguably, anti reflective coatings are more socially beneficial whilst conversating as artificial or natural light can pass straight through your lenses.
During long periods of visual focus, anti glare lenses reduce the strain on your eyes as they focus. By reducing the distraction of reflections across the lens, your eyes are given a clearer view, accumulating to an easier focal “load.”
Anti reflective is amongst several secondary lens coatings which can commonly be confused with anti scratch. These coatings are not the same thing but can be used together to improve the performance and longevity of your prescription lenses.
Lenses with a high refractive index are renowned for reflecting more light than standard index lenses. This is because they’re made from a denser material therefore are much more reflective. As such, it’s a good idea to opt for this coating if you use a thinned lens.
Are anti glare glasses worth it?
At Banton Frameworks, we’re proud to offer anti glare and anti scratch lens coatings with all our prescription lenses. There’s no need to worry about any additional costs because we’ve got your lenses covered.
Can anti glare be added afterwards?
It’s possible for anti glare coating to be applied to uncoated lenses after purchase, however this is an uncommon service in modern optics.
For quality and longevity, anti glare is predominantly applied to lenses prior to purchase. This is because the lens surfaces are in virginal condition, free from scratches and dirt which can impede any post-purchase coating.
Do anti glare glasses help night driving?
A major benefit of anti glare glasses is their ability to improve driving at night. Up to 50% more light is transmitted through the lens which enables greater vision during dark evening driving.
Furthermore, distracting reflections from oncoming or trailing headlights can pass through either side of your lens which can help you focus more easily.
How much does anti glare coating cost?
On and offline optical vendors are known to charge an additional price for an anti glare lens coating. On average, this can be as much as £30.

How do you clean anti glare lenses?
The best way to clean lenses with anti glare is by immersing your glasses warm water with a mild concentration of detergent.
This will help soften any stubborn oil or dirt on your lenses which can be wiped clean and dry with a microfibre cloth.
Avoid using any abrasive materials to clean your glasses to prevent damaging the surfaces or your lenses or the surrounding frame-rim.
Does anti glare block blue light?
Anti glare is designed to increase the amount of visible light which can pass through an optical lens.
HEV light (high energy visible) isn’t the same frequency as visible light and will pass through any lens without a blue light protective coating.
The efficacy of blue light protection remains unproven. At Banton Frameworks, we offer blue light protection as a secondary coating which you may wish to have added to your glasses.

How long does anti glare coating last?
Anti glare is externally applied to the front and backside of an optical lens. If treated roughly, this coating may begin to wear and become scratched, especially if your lenses don’t have an anti scratch coating on them.
However, if you treat your spectacles with care, anti glare can last for several years and still function well.
How can I tell if my glasses have anti glare?
The most recognisable side effect of anti glare is the way your lenses reflect light. If your lenses reflect blue, purple or green on its surface, they have an anti glare coating. If your lenses reflect the same colour as the light-source, your lenses do not have this coating.
Is anti glare and anti reflective the same?
Anti glare and anti reflective are both the same type of lens coating.
This additional coating increases the transmission of light through your lenses which improves your visual acuity and makes your eyes more visible.
Other names for this coating include AG, AR or sometimes MAR which stands for multi anti reflection.
