What Are Anti-Reflective Lens Coatings?

When ordering a new pair of glasses your optometrist will ask whether you want to customize your lenses. One of the most popular options: anti-reflective (AR) lens coatings that reduce glare.

Below, we’ll explain how AR coatings work and why they’re so favored.

What Are Anti-Reflective Lens Coatings?

AR coatings are lens enhancements that reduce glare from the front and back surfaces of each lens. They help to improve how light is transmitted through the lens, and into your eye. Most anti-reflective coatings allow 99.5% of light to pass through the lens, compared to 92% with regular lenses.

This specialized coating is a microscopic layer of metal oxides that neutralize reflections.

What Are Some Benefits of AR Coatings?

Lenses without AR coatings have visible glare, which means that light is being reflected off of their surfaces, reducing the amount of light passing through the lens. This can impair the clarity and contrast of your vision, especially at night.

Driving at night becomes much easier when you have AR coatings on your glasses. The halos around vehicle lights are greatly diminished.

AR coatings can also reduce eye fatigue and certain symptoms of digital eye strain. Because your eyes receive more light, they don’t have to work as hard to capture a clear image.

Another benefit of AR coatings: they improve the appearance of your glasses and your eyes. Whoever is looking at you won’t be distracted by reflections and glare bouncing off your glasses. Instead, they’ll have a clear view of your eyes, allowing for better eye contact.

Anti-reflective coatings can be applied to regular eyeglasses as well as sunglasses, for optimal clarity throughout your day.

How to Choose the Right Lenses for Your Glasses

Buying glasses is no easy task because there are so many elements to consider. Not everyone has the time to research eyeglass lens materials, designs and coatings.

To make it easier, we’ve compiled a list of different lenses and coatings that offer the best features for your needs.

Types of Lenses and Coatings

Glass lenses

All eyeglass lenses used to be made from glass. Although they offer excellent optics, they’re heavy and can easily crack and break, which can cause harm to the eye. This is why it is very rare to come across such lenses nowadays.

Plastic lenses

Lenses for eyeglasses moved from glass to plastic in the early 1980s as lightweight plastic eyeglass lenses (CR-39) weigh half of what glass lenses weighs, cost less, and possess exceptional optics.

Polycarbonate lenses

Originally these types of lenses were used for safety glasses. Later on, they were used for regular glasses. Polycarbonate is lighter and significantly more impact-resistant than CR-39 plastic, making it a preferred material for children’s eyewear, safety glasses and sports eyewear.

Trivex lenses

Trivex is a urethane-based pre-polymer. It is a newer lightweight eyeglass lens material that is a stronger, more resistant, clearer alternative to standard polycarbonate.

High-index plastic lenses

In response to the demand for thinner, lighter eyeglasses, a number of lens manufacturers have introduced high-index plastic lenses. These lenses are thinner and lighter than other plastic lenses (CR-39) because they have a higher index of refraction and may also have a lower specific gravity.

Anti-scratch coating

Most of today’s modern anti-scratch coatings (also called permagard or hard coats) can make your eyeglass lenses nearly as scratch-resistant as glass.

Anti-reflective coating

Anti-reflective (AR) coating eliminates reflections in lenses that reduce contrast and clarity, especially at night. AR-coated lenses are also much less likely to have glare spots in photographs.

UV-blocking treatment

Cumulative exposure to the sun’s harmful ultraviolet (UV) radiation over a person’s lifetime has been associated with age-related eye problems including cataracts and macular degeneration.

Thankfully, polycarbonate and nearly all high-index plastic lenses have 100 percent UV protection built-in, due to the absorptive characteristics of the lens material.

But if you choose CR-39 plastic lenses, be aware that these lenses need an added coating applied to provide equal UV protection afforded by other lens materials.

Photochromic treatment

This lens treatment enables eyeglass lenses to darken automatically in response to the sun’s UV and high-energy visible (HEV) light rays, and then quickly return to clear (or nearly clear) when indoors. Photochromic lenses are available in virtually all lens materials and designs.
