Anti-Reflective Coating, is It Worth It?
Everything you need to know about this essential lens upgrade, from how it works to whether you need it.
Published by Direct Sight | Lens Centre
What Is Anti-Reflective Coating?
Anti-reflective (AR) coating is a thin, multi-layer treatment applied to both sides of your lenses. It works by using microscopic layers of metal oxides that cancel out reflected light, dramatically reducing glare.
Standard lenses only transmit about 91% of available light, with the rest lost to reflections. The bright flashes you notice in photos or across a room. With AR coating, lenses can transmit up to 99.5% of light.
The result is clearer, sharper vision, less digital eye strain. Lenses that look nearly invisible, so people see your eyes, not distracting reflections.
In the UK, you may hear this coating referred to by several names:
- Anti-reflective coating (AR coating)
- Anti-glare coating glasses
- Multi-anti-reflection coating (MAR coating)
- Anti reflection glasses UK standard / reflection-free lenses
They all refer to the same core technology. Premium tiers add extra features such as blue-light filtration, oleophobic (smudge-repellent) layers, and water-repellent treatment.

The Key Benefits of AR Coating Glasses
Anti-reflective glasses coating delivers meaningful improvements across six areas:
| Benefit | What it means for you |
|---|---|
| Sharper vision | More light reaches your retina, producing cleaner, higher-contrast images, especially useful for fine detail. |
| Reduced eye strain | Less glare from screens, office lighting and devices means fewer headaches after long working days. |
| Safer night driving | Reflections from oncoming headlights and street lamps are virtually eliminated, reducing halo and glare effects. |
| Better appearance | Lenses look nearly invisible. People see your eyes, not distracting reflections, ideal for video calls and photographs. |
| Extra durability | Most modern AR coatings include scratch-resistant and oleophobic layers, extending the life of your lenses. |
| Water & smudge resistance | Premium coatings repel fingerprints and water droplets, making lenses much easier to keep clean. |
The Direct Sight Recommendation
We recommend AR coating as standard on all prescription orders. The improvement in clarity, comfort, and appearance is immediately noticeable. For anyone working at a screen, driving in low light, or wearing high-index lenses, it is not optional, it is essential.
Types of Anti-Reflective Coating Available at Direct Sight
Not all AR coatings are created equal. We offer a range of tiers to suit different needs and budgets:
Standard AR Coating, Our entry-level option. Reduces surface reflections on both lens surfaces, improving light transmission and reducing glare. Suitable for light screen use and general everyday wear.
Premium AR Coating, Adds oleophobic (fingerprint-repellent) and hydrophobic (water-repellent) outer layers for easier cleaning, alongside enhanced scratch resistance. Ideal for busy day-to-day lifestyles.
Blue-Light AR Coating, Incorporates a blue-violet light filter alongside full AR performance. Recommended for heavy screen users, gamers, and anyone who experiences evening eye strain or disrupted sleep from digital screens or artificial lighting sources.
How to Care for AR-Coated Lenses
Anti-reflective coatings are durable, but they need a bit more care than uncoated lenses. This helps maintain their performance and longevity. Follow these Direct Sight-approved guidelines:
Always wet the lens first. Never wipe a dry AR-coated lens. Dust particles can micro-scratch the surface. Use a spray lens cleaner or water to dampen before wiping.
Use a clean microfibre cloth. Microfiber cloths are the safest tool for cleaning coated lenses. Avoid tissues, clothing, or paper as they can leave micro-scratches.
Use optician-approved cleaning products. Harsh chemicals, solvents, and household glass cleaners can degrade the coating layers. Stick to products specifically formulated for ophthalmic lenses.
Store your glasses in a hard case. When not wearing your glasses, keep them in a protective case to avoid surface contact with abrasive materials.
Avoid extreme heat. Prolonged exposure to high temperatures (such as leaving glasses on a car dashboard in summer) can cause AR coatings to craze or peel over time.
Anti-Reflective vs Anti-Glare: Is There a Difference?
Anti-reflective coating (AR coating) is the technically precise term. It refers to the optical multi-layer treatment applied to lens surfaces to reduce reflected light.
Anti-glare coating glasses is the consumer-facing name for the same technology. It describes the experienced benefit (less glare) rather than the mechanism.
In practice, when a UK retailer mentions anti-glare glasses, anti reflection glasses UK, or AR coating glasses, they are almost always referring to the same lens treatment.
At Direct Sight, we use both terms interchangeably to reflect the way our customers search for this upgrade. The coating itself is identical.
AR Coating vs Polarised Lenses
Polarised lenses block specific horizontal light waves, making them excellent for outdoor glare from water, snow, and wet roads. However, their tint makes them unsuitable for night driving and indoor use.
Anti-reflective (AR) coating works differently. Instead of blocking the amount of light, it allows more of it to pass through the lens by reducing surface reflections. This improves clarity without darkening your vision, making AR coating effective in all environments. Indoors and outdoors, in bright light or low light, day or night.
AR coating can be added to polarised lenses during checkout at Direct Sight.

Frequently Asked Questions
What is anti-reflective coating on glasses?
Anti-reflective coating (also called AR coating or anti-glare coating) is a thin multi-layer applied to the surfaces of eyeglass lenses.
Each layer uses optical interference to cancel out reflected light waves. Allowing up to 99.5% of light to pass through the lens and reach your eye. This results in sharper vision, reduced glare, less eye strain, and lenses that appear nearly invisible . People see your eyes rather than distracting reflections.
Do I need anti-reflective coating on my glasses?
While not essential, anti-reflective coating is highly recommended for most glasses wearers. Especially beneficial if you spend long hours in front of screens, drive at night, wear high-index or progressive lenses.
AR coating is considered essential for high index lenses, as these lenses naturally reflect more light than standard plastic. That’s why all our high-index lenses come with AR coating as standard.
What is the difference between anti-glare coating and anti-reflective coating?
There is no practical difference for eyeglass wearers. Anti-reflective coating is the technical, optician's term describing the multi-layer optical treatment. Anti-glare coating is the consumer-friendly description of what the coating achieves, reducing visible glare. UK retailers use both terms to describe the same lens technology.
Is anti-reflective coating worth the extra cost?
Yes, for most people. The improvement in visual comfort, particularly for screen users and night drivers, is immediate and significant. Premium AR coatings also add durability benefits such as scratch resistance, smudge repellency, and water resistance. It helps to extend the usable life of your lenses and keep them looking cleaner for longer.
At Direct Sight, we include AR coating as standard on our lens high index lens packages.
Can I get anti-reflective coating on any type of glasses?
Anti-reflective coating can be applied to virtually all prescription lens types, single vision, bifocal, and progressive (varifocal) lenses. It is compatible with glass, standard plastic (CR-39), polycarbonate, and high-index materials. The coating is available on both clear prescription lenses and prescription sunglasses. If you are unsure whether your lens type is compatible, our team at Direct Sight can advise.
How long does anti-reflective coating last on glasses?
With proper care, a quality AR coating should last the full usable life of your lenses. It is recommended to have an eye test every two years at which point your lenses may need changing. Factors that shorten coating lifespan include using harsh chemical cleaners. Wiping your lenses when they’re dry with rough materials, or exposing them to high heat, like leaving your glasses on a hot car dashboard.
Following Direct Sight's lens care guidelines will keep your AR coating performing at its best.
Are anti-reflection glasses harder to keep clean?
Modern anti-reflective coatings include oleophobic (oil-repellent) layers that actively resist fingerprints and smudges. Making them easier to clean than previous-generation coatings. The key is to always dampen the lens before wiping and use a clean microfibre cloth.
AR coatings from a decade ago had a reputation for smudging more easily. This is no longer the case with our premium AR coating.
What are shallow framed glasses, and do they benefit from AR coating?
Shallow framed glasses have become one of the most popular eyewear trends in the UK. They are characterised by a reduced lens depth, creating a slim, horizontal silhouette. They are often ordered with high-index lenses to stay thin and preserve the frame’s minimal look.
Our high index lens options come as standard with anti-reflective coating. It keeps the lenses virtually invisible, complementing the minimalist aesthetic of the frame.
Where can I buy anti-reflection glasses in the UK?
Direct Sight offers a full range of anti-reflective coating options across our prescription lens packages. Available online and ready to add to any frame from our collection.
Our anti-glare coating is available on standard index and high index lens options. Photochromic, Polarised and sun tinted options can also be paired with anti-reflective coating. All supplied with a UK-based customer support team.
