This is the most important option you can add to any set of lenses regular or sunglass. A/R coat cancels the surface reflections and ghost images that float around on lense surfaces as your head moves under room lights or the xenon and halogen headlights you see at night. Not only is vision enhanced by at least 10% increase in light transmission but the lenses now do their job as if THEY WERE NOT EVEN THERE! And A/R coat improves sunglass lens performance.
Reduce Eye Strain With Anti-reflective Coating
Anti-reflective coating improves vision, reduces eye strain and makes your eyeglasses more attractive.
The AR coating basically eliminate reflections from the front and back surfaces the lens. Due to this technology, reflection is eliminated, light passes through the lens more optimally, and the eyeglasses user experiences increased visual acuity. this technology makes the glasses appear invisible, so if that is your thing, then be ready, more people will see your eyes. For high quality interactions with others, this is a huge plus.
AR coating and High Index Lenses
AR coating is hugely beneficial with high-index lenses. Generally, the higher the index of refraction of the lens material, the more light that will be reflected from the surface of the lenses. This anti-reflective coatings helps reduce glare and light-halos, which helps improve night vision.
AR technology has significantly improved
Anti-reflective coating virtually eliminate reflection of light from eyeglass lenses. It is believed that as much as 99% of light successfully passes through these lenses to enter the eye. Which drastically improves vision.
Can anti-reflective coating improve my sunglasses?
AR coating applied to the backside of the lens can eliminate glare from sunlight reflecting into your eyes from the back surface of tinted lenses when the sun is behind you.
How Anti-Reflective Coating Is Applied?
Through a technical process involving vacuum deposition technology. First, the lenses are scrupulously cleaned, inspected and doubly cleaned. This meticulous cleaning process is imperative for effective coating.
Secondly, once the lenses are cleaned of all contaminants, they are air dried and heated in special ovens. Then loaded into special metal racks with spring-loaded openings so the lenses are held securely but with virtually all lens surfaces exposed for the coating application.
The racks are then loaded into the coating chamber. The door of the chamber is sealed, and the air is pumped out of the chamber to create a vacuum. While rotating in the chamber, a power source within the machine focuses a beam of electrons onto a small crucible that contains a series of metal oxides in separate compartments.
When the coating materials are bombarded by electrons, they vaporize within the coating chamber and adhere to the surfaces of the lenses — creating a uniform, microscopically thin optical layer on the lens.
Which AR coating is best for me?
It depends on your lifestyle. Specific brands are made for specific lifestyles and activity levels. Some AR coating are best fit for computing and electronics where others are better suited for outdoors and night time.
How do I care for my Anti-Reflective Lenses?
Consult your optician. Lens cleaners with harsh chemicals may damage the anti-reflective coating.
