What is an Anti-Reflection Coating?
In simple terms, an Anti-Reflection (AR) Coating is a special type of lens enhancement that is applied to the lens surface to improve the transmittance of light through the lens.

Uncoated regular plastic lenses reflect roughly 8 percent of light hitting the lenses, so only 92 percent of available light enters the eye for vision. This reduces the clarify and contract of vision seen through these lenses.

In cases of much higher prescriptions where high index plastic lenses are needed, these lenses can reflect up to 50 percent more light than regular plastic lenses (approximately 12 percent of available light), so even less light is available to the eye for vision. This can be particularly troublesome in low-light conditions, such as when driving at night.

GlimmAR anti-reflective coatings can virtually eliminate the reflection of light from lenses, thus allowing 99.5 percent of available light to pass through the lenses and enter the eye for good vision.

Additionally, GlimmAR lenses also prevents harmful blue light from entering your eyes by reflecting between 30-40% of this blue light as it hits the lens surface.

The coating is actually made up of multiple layers which include :

– Hydrophobic layer (repels water from the surface of the lens)
– Oleophobic layer (repels dirt and oils from the surface of the lens)
– Multiple Anti-reflection layers (superior light reflection and maximum transmission)
– Blue Reflection layer (protects the eyes from harmful blue light)
– Anti-scratch layer (prevents the lens from scratching easily)

Benefits of Anti-Reflection Coatings
Anti-reflective coatings improve vision, reduces eye strain, improves night driving, reduces glare from your computer and makes your glasses look more attractive.

In simplistic terms, these benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your lenses.

When you have light being transmitted through the lenses instead of being reflected off the lenses, more light passes through to your eyes which optimizes visual acuity with fewer distractions/distortions.

More light entering the eyes means improved vision. When things are easier to see the eyes work less and as such less eye strain is experienced.

AR coatings reduce glare coming from computers providing much better comfort and less eyestrain during prolonged computer use as the eyes don’t have to focus as hard on the small numbers and letters.

Additionally, night driving is greatly enhanced as the increased light transmission improves visual clarity, halos around street/car lights and reflections when driving at night.

Because of the anti-reflection feature, the lenses look nearly invisible (apart from a blue hue as a result of the blue light reflection feature) and this enhances your appearance by drawing more attention to your eyes and helping you make better “eye contact” with others.

Finally, as already stated, AR coatings are especially beneficial when used on high-index lenses (which is required for people with higher prescriptions) as these lenses reflect more light than regular plastic lenses. Generally the higher the index of the lens material, the more light that will be reflected from the surface of the lenses.
