Anti-glare coating, also known as anti-reflective coating or AR coating, is a thin layer applied to the surface of your eyeglass lenses that allows more light to pass through your lenses. This improves your vision by reducing the amount of glare that reflects off of your lenses.
Glare is the excessive brightness caused by direct light or reflected light. It often occurs when sunlight bounces off a reflective surface like water or snow. Phones, tablets, and computer screens lit by LEDs can also cause glare.
Standard plastic lenses reflect approximately eight percent of the light that reaches your glasses, and high-index lenses reflect up to 12 percent of available light.
Glare can cause numerous problems, including:
Anti-glare coating allows 99.5 percent of available light to reach your eyes, essentially eliminating glare.
Anti-reflective coating is available on all eyewear lens types, including high-index lenses, bifocals and multifocals, progressive lenses, reading glasses, and sunglasses.
AR coating provides numerous benefits, including:
With no light reflecting off of your lenses, more light will reach your eye. This increases visual acuity and reduces the need to squint, especially during deep focus tasks like driving or using your computer.
If you have glasses without anti-glare coating, you’ve probably had issues with taking good pictures or finding the right angle for video calls. Any bright lights or camera flash will reflect off of your lenses. The same is true when you’re speaking to someone face to face in a bright setting. Anti-reflective lenses eliminate this glare so that everyone can see your eyes.
Anti-reflective coating also helps protect your eyes from UV rays (sunlight that doesn’t appear on our visual spectrum). This property can be enhanced by purchasing photochromatic (transition) or polarized lenses.
Glare can be a big problem in many outdoor sports. Fishing, skiing, snowboarding, and baseball all take place in very bright settings that have the potential for a lot of glare. Anti-reflective glasses or sunglasses help to reduce this light and provide you with a clear field of vision.
Glare can cause serious problems during deep focus tasks or work that takes place on a screen. Anytime you need to squint to see something, you are straining your eyes. Eliminating glare during these tasks will help put less stress on your eyes.
Digital devices such as phones, laptops, tablets, and TVs all emit harmful blue light. Some anti-glare coatings help to reduce your exposure to blue light, improve your sleep pattern, and reduce eye strain. These are common on blue light blocking glasses (also called computer glasses).
Many anti-glare lens coatings also undergo a hydrophobic surface treatment that makes them resistant to water. This also makes them easier to clean. However, due to their complete transparency, fine scratches are more visible on anti-glare lenses.
When cleaning your anti-glare lenses, be sure only to use products that your optician recommends. Always be sure to wet or moisten your lenses as well, using a dry cloth on dry lenses may cause dust or other debris to scratch your lens.
Anti-glare coating can cost anywhere from $20 to $150 in addition to the original cost of your lenses. The cost will depend on the type of AR coating you choose and your eye doctor’s pricing. Some companies will include AR coating free of charge when you purchase their lenses.
Yes anti-glare coating allows nearly 100 percent (99.5) of available light to reach your eyes, which virtually eliminates glare.
An additional $20 to $150 along with the original cost of your lenses. The total cost depends on the type of AR coating you choose and your eye doctor’s pricing. Some doctors or companies will provide free AR coating when you purchase lenses from them.
Yes anti-glare coating can be applied to your lenses after purchase as long as the lens has no scratches and has not been exposed to skin oils. However, it may be much more expensive to get the coating applied afterwards rather than during the manufacturing process.
Anti-glare coating provides numerous benefits including better visual clarity, UV protection, reduced eye strain, and better appearance. The only con is the additional cost. Nearly all eye care professionals would recommend anti-glare coating on your lenses.
