Anti-Reflective Coating (AR) coating is a special treatment applied to eyeglass lenses to reduce reflections from light sources. This can help to improve vision, reduce eye strain, and make glasses more comfortable to wear.

How AR Coating Works

AR coating works by applying a thin layer of transparent material to the surface of the lens. This layer has a refractive index that is different from the refractive index of the lens material. This difference in refractive indices causes light to refract (bend) as it passes through the lens, and some of the light is reflected away from the lens. The amount of light that is reflected is dependent on the thickness of the AR coating and the wavelength of the light.

Benefits of AR Coating

There are many benefits to wearing glasses with AR coating. These benefits include:

Reduced glare: AR coating can significantly reduce glare from light sources, such as headlights, computers, and the sun. This can improve vision, especially at night or in bright conditions.

Reduced eye strain: Glare can cause eye strain, which can lead to headaches, fatigue, and blurred vision. AR coating can help to reduce eye strain by reducing glare.

Improved visual acuity: AR coating can improve visual acuity by allowing more light to pass through the lens. This can be especially beneficial for people with low vision.

More comfortable glasses: AR coating can make glasses more comfortable to wear by reducing glare and eye strain.

Other Benefits of AR Coating

In addition to the benefits listed above, AR coating can also:

Make your eyes more visible behind your glasses

Reduce the appearance of scratches and smudges on your lenses

Make your glasses easier to clean

Protect your lenses from scratches and wear

Who Should Consider AR Coating?

AR coating is a good option for anyone who wears glasses, but it is especially beneficial for people who:

Spend a lot of time in front of a computer or other digital devices

Drive at night

Experience glare from headlights or other light sources

Have low vision

How to Get AR Coating

AR coating is available on most types of eyeglass lenses. You can get AR coating added to your lenses when you purchase your glasses, or you can have it added to your existing lenses.

Cost of AR Coating

The cost of AR coating will vary depending on the type of lens and the thickness of the coating. However, AR coating is generally worth the investment, given the many benefits it offers.


AR coating is a valuable addition to any pair of glasses. It can improve vision, reduce eye strain, and make glasses more comfortable to wear. If you are considering AR coating, talk to your eye doctor to see if it is right for you.
