There are over 143 million adults in America who wear glasses. Many of these adults opt to have an anti-reflective coating applied to their lenses for a variety reasons. Anti-reflective coating not only improves the appearance of the glasses but also the vision seen through the lenses. Additional benefits of anti-reflective lenses include durability, heat resistance, aid in night driving, easy cleaning, and resistance to scratches.
The highest quality anti-reflective coating has a hydrophobic, or water-resistant, layer that is made to prevent water spots from developing on the lens and also makes them much easier to clean. Some anti-reflective coatings also have an oleophobic, or oil-resistant, layer that resists oil from the skin and once again makes it easier to clean smudges off of the lenses.
Today, anti-reflective coatings have even become very popular with sunglasses. When applied to the backside of the sunglass lenses, anti-reflective coating reduces the reflections of the sunlight into the eyes when the sun is coming in from behind.
There are many reasons why an anti-reflective coating is added to the lenses of a pair of glasses or sunglasses. This coating is often chosen for appearance, as it improves transparency and reduces the reflections in the glasses. The anti-reflective coating on lenses makes it easier for a glasses wearer to have direct eye contact with someone else without all of the distractions of reflections.
The anti-reflective coating helps improve driving safety, especially at night, by eliminating distracting headlights and streetlights. This allows drivers to focus more on the road.
Also, while working, the unnatural and artificial lights found in many offices can quickly cause eye fatigue.
Using a computer likewise puts great strain on the eyes. Having an anti-reflective coating applied to lenses will help to protect the eyes while working.
Last but not least, an anti-reflective coating on a lens enhances the quality of a lens and also lengthens its lifetime by providing durability and resistance to water, dirt, and scratches.
The problems glare can cause
So, why do we care about glare? Well, it can present numerous problems for wearers, especially when driving, playing sports and working with computers and other tech with direct light sources. The result is inhibiting vision and attributing to health issues, including eye strain, blurred vision or ‘halos’ around bright lights such as street lamps, headaches, migraines and a significant decrease in concentration and focus when squinting to avoid glare. On the odd occasion, it may not seem like a priority to have anti-glare, but once these health issues become chronic, you can have very real, very uncomfortable health issues to deal with.
Do I need anti-glare lenses?
Anti-glare lenses are suitable for everyone, especially in our predominantly digital workspaces, working from home, TV streaming and internet heavy lives we lead. And while some people suffer from the effects of glare more than others, the exposure to digital screens and then natural light to take a break from them will only ever increase. Computer screens, driving at night, and sun exposure are all very different scenarios that can be marred by the effects of glare. And while AR coating does not guarantee reflection elimination, wearing anti-glare lenses will reduce fatigue in your eyes and headaches as a result by lessening the amount of reflection and light coming through your lenses.
Anti-glare coating is layered on both the front and back end of a lens, designed to manipulate incoming light. It allows your eyeglasses to provide you with optimal vision. An anti-glare coating is incredibly effective when applied, blocking up to 99.5% of incoming light. This makes reflections practically invisible. eResearch by Navid Ajamin -- winter 2011
Glare in your eyes can be hazardous to you and everyone around you. It can obstruct your driving at nighttime and during the day. UV light can be damaging to your eyes as well—too much exposure can lead to diminishing eyesight, dryness, and loss of elasticity.
