Anti-reflective coating (ARC)

Anti-reflective coating, anti-scratch coating, hydrophobic coating.
Anti-reflective coating reduces the glare that you see, as well as the glare that others can see on your lenses

Aantireflective or anti-reflection (ARcoating is a type of optical coating applied to the surface of lenses to reduce reflection. It can enhance the performance and appearance of your eyeglass lenses.

AR coatings are similar to the coatings found on microscopes and camera lenses. They consist of several layers of metal oxides applied to the front and back lens surfaces. Because of the layering effect, AR coatings sometimes have a hint of green or purple color, depending on the individual manufacturer's formula.

Anti-reflective coating reduces both internal and external reflections on the lenses themselves, creating a nicer cosmetic appearance. Internal reflections appear as rings that make lenses look thick. External reflections mask your eyes from a clear, complete view when someone is looking at you.

Advantages of AR Coating

  • Getting an anti-reflective coating applied to your lenses is a smart choice. The plastic lenses generally used in glasses or sunglasses usually transmit only 90% of the available light to the eyes. The remaining 10% of light is often obstructed by reflections on the lenses.
  • ARC improve efficiency where light would normally be lost due to reflections. It was originally created to reduce reflections on camera lenses and is now also used to improve the vision of millions of people who wear glasses or sunglasses.
  • It makes it easier for a glasses or sunglasses wearer to have direct eye contact with another person without his or her view being obstructed by reflections.
  • By reducing glare, it makes vision more crisp and clear than would be possible if the lenses were not coated.
  • It improves driving safety by allowing drivers to focus on the road without distractions from headlights and streetlights.
  • It reduces eyestrain for people who use computers often by decreasing glare from the computer screen.
  • It reduces eye fatigue for people who work in offices by lessening overhead glare that can be caused by unnatural lighting often found in offices.
  • It enhances the quality of a lens and also lengthens its lifetime by providing durability and resistance to water, dirt, heat, and scratches.

There are different types of anti-reflective coating. The best quality anti-reflective coatings are water-resistant because of a hydrophobic layer that prevents water spots from developing on the lens. This same hydrophobic layer makes it easier to clean lenses without damaging them. Another layer anti-reflective coatings may include is an oleophobic layer. The oleophobic layer makes lenses resistant to the oil that is naturally excreted through your skin or any moisturizers you may wear. This layer also makes it easier to clean smudges off your lenses.

Getting an anti-reflective coating applied to your lenses is a great choice because they reduce reflections on your glasses or sunglasses and improve the durability of your lenses. Additional advantages are: less eyestrain, less eye fatigue, better vision, better eye contact, and safer driving.
