How does an anti-reflective coating work?

An anti-reflective, (also known an as ‘AR’ or anti-glare coating) is an essential addition to your glasses. This coating reduces reflections on the front and back of the lenses of your glasses from 95 – 99.5%. This allows more light to pass through the lens, improving your vision.

Regular plastic lenses reflect roughly 8 percent of light hitting the lenses, so only 92 percent of available light enters the eye for vision. High index plastic 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.

How do anti-reflective lenses help my cosmetic appearance?

Because less light reflects off the lens, the eye behind the lens is more visible. This allows you to hold eye contact easily and allows others to see your eyes easily.

You can confidently look your best in all lighting conditions now the lens is nearly invisible.
An AR coating also reduces the risk of scratches significantly by increasing the lenses’ durability, making sure your glasses last longer.

Do anti-reflective lens coatings help me with my driving?

An anti-reflective coating reduces reflections back to the white of the eye, which reduces bright glare effects. This increases the contrast of your surroundings, and reduces the glare on oncoming car headlights, street lights and neon signs when driving at night.

Fewer reflections means fewer distractions, helping with your concentration when night driving.

Will an anti-reflective coating help me look at screens comfortably?

Yes, the reduction of reflection from blue light means that you will be able to look at screens longer and with greater comfort.

If you have an office job or a position where you spend a lot of time around screens, anti-reflective coating is highly recommended as it can reduce eye fatigue due to a decrease in glare to process.

How does an anti-reflective coating help those who need high-index lenses?

An AR coating is an essential for those who wear high-index lenses, as uncoated standard plastic lens reflects 8% of light, whereas an uncoated high index plastic lens will reflect up to 50% more. A rule of thumb is the higher the index, the greater the amount of light reflected. This can lead to increased difficulty with night driving, but also eye fatigue due to decreased light transmittance.

With an AR coated lens however, the light transmittance can increase to 99.5%. As a result, reflections and chromatic aberrations are reduced. You will have a clearer view of your surroundings, and the glasses will have a better cosmetic appearance.

Looking after lenses with an anti-reflective coating

Talk to your opticians before cleaning your lenses with a special lens cleaner. Some of these are harsh and can damage the very thin anti-reflective coating. Make sure you use a wet cloth over dry to keep the coating unscratched.
