Reasons For Using Anti-Reflective Coatings

Whenever we look at the mirror, we see the exact spitting replica of ourselves. Though the mirror provides us an image that is a reversed version of the original, still the result’s pretty much the same. While reflections at most are beneficial, there are times that it can become bothersome.

Take the case of prescription lenses. One uses a prescription lens to aid one’s failing vision. However, what makes wearing one quite bothersome are the reflections that one can see on the glass itself. And when that happens, it greatly reduces your vision. This can become more of a hazard, especially during night time.

Now that we’re on the topic, how does an optical coating company reduce this? The ultimate solution for this would be to coat the glass with an anti-reflective coating? But, what is it, and what are the benefits of having such?

What is an anti-reflective coating?

  • Aka anti-glare coating
  • A type of optical coating that usually applied to lenses to reduce reflection.
  • Improves efficiency of the glass or lens by removing the light lost due to reflection

How does anti-reflective coating work?

  • Reflection occurs when a light passing through glass bounces back to the surface
  • Anti-reflective coating reduces the amount of light that bounces back, allowing more light to pass through the glass

Why does one need to use anti-reflective coating?

  1. Lessens glare and allows more light to pass through
  • Anti-reflective (AR) coating is applied on glass surface to allow more light to pass through, resulting in sharper and clearer vision
  • Less glare on glasses
  • Reflection of glare on lenses  makes it difficult for people to see your eyes
  • Improves cosmetic appearance of the wearer with glare removal
  • Reduces eye strain
  • Eyes relax more when glare is removed as more light passes through the lens
  • Improves image contrast
  • AR coating eliminates the stray light that often appears on microscopes and telescopes

For more information on AR coating, you can always ask the company you’re working with.
