Anti-Reflective Coating
Why Should I Choose Anti-Reflective Coating?
The anti-reflective coating or anti-glare coating (sometimes referred to as AR or MAR) will help improve your vision and also reduce the glare from your lenses, making them more attractive to look at as people will not get any reflection off your lenses when looking at you.
This coating will remove reflections, thus allowing more light to pass through the lens, which will optimise your sight, especially at night.
Anti-reflective coating also helps people to see your eyes instead of getting glare from your glasses.
This is why we recommend anti-reflective coating to everyone and it can be found in any of our packages from Silver and above.
How Do We Apply an Anti-Reflective Coating to Your Glasses?
Applying this AR coating to lenses is a very complex process which involves using vacuum deposition technology.
Firstly, the lenses have to be cleaned to within a inch of their lives. The smallest grain of dust can cause a problem in the finished coating.
The lenses are washed multiple times to remove any contamination and ultrasonic baths. They are then dried and heated to ensure no moisture is left on the lens.
The lenses are then clamped and loaded into the machine.
The anti-reflective materials are bombarded by electrons and vaporised within the coating chamber until they "stick" to the surface of the lens. This creates a perfect, microscopically thin optical layer on the lens.
This equipment is highly expensive, but you can see that is not a quick job.
This procedure is carried out when your lenses are still the size of a small saucer and clamped at the edges. As a result, we cannot apply the coating retrosecitvely, so ensure you select anti-reflective lenses when ordering your lens packages.
