Sunlight that hits corrective lenses can bounce back off them, causing a glare that can be disturbing for the wearer and distracting for people who are socializing with her. This is because it causes distracting reflections on the front and back of the lenses. Optometrists can put an anti-reflective coating on corrective lenses to reduce these unwanted distracting reflections. This thin special coating has benefits for the eyeglass wearer. This super thin material really improves the clarity of vision, and makes a person's eyes less tired at the end of a typical day.
Since sunlight can reflect off the front and back of lenses, both sides are treated with the thin coating.
When images bounce off the back of prescription lenses, it is very distracting for the wearer. In addition, the glare from light that bounces off the back of the lenses goes straight into the wearer's eyes, making it very difficult for the wearer to see. This leads to eye strain. An anti-reflective coating on the back of lenses can prevent this issue.
Light bouncing off the front of glasses can make it hard for other people looking at the wearer to see the wearers eyes. They instead see the their own reflection. A thin coating makes the prescription lenses less obvious and allows the wearer's eyes to be clearly seen.
An individual who wears eyeglass lenses while working on a computer may experience a distracting glare as the light from the computer screen hits the corrective lenses. This glare is regularly the source of headaches, especially when combined with artificial office lighting. Corrective eyeglass wearers realize significant benefits from having this thin coating applied to corrective lenses, especially when the wearer wears their glasses while working on the computer.
Both glass and plastic eyeglasses reflect some of the light that hits them. Anti-reflective coating significantly improves the vision of the wearer, due to the fact that they allow extra light to pass through, and greatly reduce the glare. This is very critical when driving at night.
Anti-reflective coating can also be useful when applied to the back of the lenses in sunglasses. The AR coating reduces the glare that hits the wearer's eyes when someone turns her back to the sun. This is commonly known as 'bounce-back' reflection. An anti-reflective coating is normally not applied to the front of sunglasses.
It is very important to use mild cleaning products on anti-reflective lenses. Harsh, abrasive cleaners definitely will damage the applied coating.
While anti-reflective lenses are definitely more expensive than untreated lenses, they can be valuable because they reduces distractions.
