Lens Coatings Explained

Written by Scott Phippen UK Registered Dispensing Optician 8 min read

A clear, practical guide to help you make a more confident decision before ordering prescription glasses online.

Lens coatings are one of the most misunderstood parts of buying prescription glasses. The words sound technical: anti-reflection, scratch-resistant, UV protection, blue light, hydrophobic, oleophobic and easy-clean. Some coatings are genuinely useful. Some are useful for particular people. Some are oversold. The difficult part is knowing which ones actually matter for your glasses.

The honest answer is that lens coatings should not be chosen like random upgrades at checkout. They should be chosen based on how you use your glasses, where you wear them, how often you clean them, whether you drive at night, whether you work at screens, and whether you are buying clear lenses, sunglasses or light-reactive lenses.

This guide explains the main prescription lens coatings in plain English, including what each one does, who benefits from it, which coatings are worth paying for, and where customers often get confused. The aim is not to tell you to buy every coating. The aim is to help you choose the right lens finish for real everyday use.

Burghley Handbook

The simple rule

Good coatings make lenses clearer, easier to live with and more comfortable in real use. Badly chosen coatings add cost without solving the actual problem. Start with how you use your glasses, then choose the coating.

What are lens coatings?

Lens coatings are specialist treatments applied to the lens surface. They do not normally change your prescription power. Instead, they change how the lens behaves in everyday conditions. A coating can reduce reflections, resist minor scratches, repel water, make cleaning easier, filter certain wavelengths of light, or improve comfort in bright conditions.

The lens itself corrects your vision. The coating improves how practical, clear and comfortable that lens feels when you actually wear it. This is why two lenses with the same prescription can feel quite different. One may reflect every ceiling light and smudge easily. Another may look clearer, clean more easily and feel better at night or under artificial lighting.

THE LENS POWER

Corrects your vision

Your prescription determines the optical power needed to correct short-sight, long-sight, astigmatism or reading vision.

THE COATING

Improves lens performance

Coatings affect reflections, cleaning, glare, durability, water resistance and comfort in different environments.

Scott’s Professional Advice

Do not confuse lens type with lens coating.

Single vision, varifocal and occupational lenses describe what the lens is designed to do. Coatings describe how the lens surface performs. You need both decisions to make sense.

Why lens coatings matter

Coatings matter because prescription glasses are worn in the real world, not in perfect lighting. You wear them under shop lights, at computer screens, in the car, on video calls, in rain, in bright sun, around fingerprints, dust and cleaning cloths. Bare lenses can work optically but still be frustrating to live with.

Anti-reflection coating is often the most noticeable everyday improvement because reflections can be distracting and make the lenses look less clear. Easy-clean and water-repellent layers can make the glasses easier to maintain. Scratch-resistant coatings help protect the surface from minor wear, although no coating makes lenses completely scratch-proof.

Problem Helpful coating What it improves
Reflections from lights, screens or headlights Anti-reflection Clearer-looking lenses and less distracting glare
Minor surface wear Scratch-resistant hard coat Better resistance to everyday marks
Water spots and rain Hydrophobic coating Water beads and runs off more easily
Fingerprints and greasy smears Oleophobic / easy-clean coating Easier cleaning and less stubborn smearing
Screen-heavy lifestyle Blue light filtering coating May improve comfort for some wearers
Outdoor UV exposure UV protection Helps protect eyes from ultraviolet light

Anti-reflection coating explained

Anti-reflection coating, often called AR coating, reduces reflections from the lens surfaces. Without it, lenses can reflect light from screens, car headlights, shop lighting, office lighting and camera flashes. These reflections can be distracting for you and can also make it harder for other people to see your eyes clearly.

For most everyday clear prescription glasses, anti-reflection coating is one of the most worthwhile lens options. It helps the lenses look cleaner and more transparent. It can improve comfort under artificial lighting. It is also helpful for night driving because reflections from headlights and street lighting can otherwise feel more noticeable.

WITHOUT AR

More reflections

Lenses may reflect lights and screens more noticeably, which can make them look cheaper and feel more distracting.

WITH AR

Clearer-looking lenses

Reflections are reduced, your eyes are easier to see and the lenses usually look more refined.

Visual explanation

What anti-reflection coating actually does

Think of an uncoated lens as a small mirror as well as a lens. Anti-reflection coating reduces that mirror-like surface effect, so more attention goes through the lens rather than bouncing back off it.

Scott’s Professional Advice

Anti-reflection is not a luxury for regular glasses.

If you wear clear prescription glasses every day, I would usually recommend anti-reflection coating. It improves the appearance of the lenses and helps reduce distracting reflections. It is one of the coating choices customers are most likely to notice.

Scratch-resistant coating explained

Scratch-resistant coating is a hard coating applied to help protect the lens surface from everyday minor wear. It is important to be honest here: scratch-resistant does not mean scratch-proof. No normal spectacle lens coating can make lenses impossible to scratch.

What it can do is improve resistance to small marks caused by day-to-day handling, cleaning and wear. This is especially important because most modern lenses are plastic rather than glass. Plastic lenses are lighter and safer, but they benefit from a hard coating to improve surface durability.

Scratch-resistant does not mean indestructible

Lenses can still scratch if they are cleaned dry with grit on the surface, placed face down, kept loose in a bag or wiped with unsuitable materials. Coatings help, but care still matters.

How to reduce lens scratches

  • Rinse lenses before wiping if dust or grit is present
  • Use a proper microfibre cloth
  • Avoid tissues, sleeves and rough fabrics
  • Keep glasses in a case when not being worn
  • Do not place glasses lens-down on tables
  • Avoid leaving glasses in hot cars or harsh environments

UV protection explained

UV protection helps protect the eyes from ultraviolet light. This is especially important for sunglasses, but UV protection can also be relevant in clear lenses depending on the material and coating. Customers often assume darker lenses automatically mean better protection, but darkness and UV protection are not the same thing.

A dark lens without proper UV protection is not the goal. The lens should reduce brightness and protect against UV. Proper prescription sunglasses should be chosen as optical products, not just as fashion tints.

DARKNESS

Reduces brightness

A tint changes how much visible light reaches your eyes. It makes the lens feel darker in bright conditions.

UV PROTECTION

Protects from ultraviolet light

UV protection is about filtering ultraviolet radiation, not simply making the lens darker.

Scott’s Professional Advice

Do not judge sunglasses by darkness alone.

A sunglass lens should provide proper UV protection as well as comfort in bright light. If glare is the main problem, polarised lenses may be more useful than simply choosing a darker tint.

Hydrophobic coating explained

Hydrophobic means water-repelling. A hydrophobic coating helps water bead and run off the lens surface more easily. This can be useful if you wear glasses in rain, move between indoor and outdoor environments, or dislike water spots after cleaning.

It does not mean rain disappears from your glasses completely. It simply makes the lens surface less attractive to water, so droplets are less likely to spread across the lens in a smeary film.

Plain English

Hydrophobic = water-repellent

If water normally spreads across a surface, a hydrophobic layer encourages it to form beads instead. That can make lenses easier to clear and clean.

Oleophobic and easy-clean coatings explained

Oleophobic means oil-repelling. In glasses, this usually refers to coatings that help resist greasy marks, fingerprints and smears. These are often described as easy-clean coatings because they make the lens surface easier to wipe clean.

This is useful for almost everyone, but especially for people who handle their glasses often, remove them regularly, wear makeup, use moisturiser, work in busy environments or simply hate constantly cleaning smudges off their lenses.

STANDARD SURFACE

Smears can cling

Fingerprints, skin oils and cleaning marks can feel more stubborn on basic lens surfaces.

EASY-CLEAN

Smears lift more easily

Premium surface layers can make the lenses easier to clean and maintain day to day.

Blue light coating explained

Blue light coatings are often marketed strongly, so they need an honest explanation. These coatings are designed to reduce or filter certain parts of blue-violet light. Many customers associate them with screens, digital eye strain and long working days at computers.

Some people like blue light filtering lenses and feel more comfortable with them, particularly under screens and artificial lighting. However, blue light coating is not a cure-all. If your prescription is wrong, your screen distance is wrong, your eyes are dry, your lighting is poor or you need occupational lenses, blue light coating alone will not solve the real issue.

Blue light is not the whole screen-fatigue story

Screen discomfort is often caused by working distance, dry eyes, glare, uncorrected prescription, poor lighting or needing a different lens design. Blue light filtering may help some people, but it should not replace proper lens choice.

If your problem is... Blue light may help? Also check
Tired eyes after screens Possibly Prescription, screen distance, dry eye, breaks and lighting
Blurred computer vision Not enough on its own Whether you need occupational or screen-distance lenses
Reflections from the screen Not the main answer Anti-reflection coating
General everyday comfort May be preferred by some wearers Lens type, coating quality and prescription accuracy
Scott’s Professional Advice

Do not use blue light coating to cover up the wrong lens choice.

If you work at a screen all day, the bigger question is whether the prescription and lens design suit your screen distance. A blue light coating can be part of the conversation, but it should not be the whole conversation.

Premium vs standard lens coatings

Not all coatings perform the same. A basic coating may reduce reflections, but a better coating may also be tougher, easier to clean, more water-repellent and more resistant to smearing. Premium coatings are usually built as multi-layer systems rather than one simple surface treatment.

The difference is often most noticeable over time. A better coating can feel easier to live with because the lenses clean better, reflect less and maintain their appearance more effectively when cared for properly. That does not mean every customer needs the most expensive coating available, but it does mean coating quality should not be ignored.

Coating level Usually includes Best for
Basic coating Simple hard coat or basic anti-reflection Occasional wear or budget-focused orders
Good everyday coating Anti-reflection, hard coat and easier cleaning Most regular prescription glasses
Premium coating Improved AR, scratch resistance, water and oil repellence Daily wear, work glasses, night driving and customers who want a better finish

Which lens coating do I need?

The best way to choose coatings is to start with the way you use your glasses. Most everyday clear prescription glasses benefit from anti-reflection coating. Many customers also benefit from easy-clean and scratch-resistant layers. Blue light is more individual. UV and sunglass coatings depend on whether the glasses are for outdoor use.

EVERYDAY CLEAR GLASSES

Anti-reflection is the priority

For regular wear, anti-reflection plus a good hard coat is usually the most sensible starting point.

SCREEN HEAVY WORK

Check lens design first

Consider anti-reflection and possibly blue light, but make sure the prescription and working distance are correct.

DRIVING

Reduce reflections and glare

Anti-reflection matters for night driving. For bright daytime glare, consider prescription sunglasses or polarised lenses.

SUNGLASSES

UV and glare protection

Choose proper UV protection and consider polarised lenses if reflected glare is a problem.

Decision guide

Start with your main problem

Lights and reflections bother you?
Choose anti-reflection coating.

Your lenses always look smeary?
Choose easy-clean / oleophobic coating.

You wear glasses all day?
Choose a good everyday multi-coating rather than the most basic finish.

You work on screens all day?
Check your prescription and lens design first, then consider blue light filtering.

You struggle with bright outdoor glare?
Look at prescription sunglasses, UV protection and polarised lenses.

Which coatings are included with Burghley & Co lenses?

At Burghley & Co, lens choices are designed to be practical rather than confusing. Everyday prescription lenses should not leave you wondering whether clear vision will be spoiled by reflections, poor finish or avoidable glare. Where anti-reflection is included, it is there because it makes sense for real daily wear.

The exact lens options available may depend on the lens type you choose, including single vision, sunglasses, photochromic or varifocal lenses. The important point is that the lens choice should be reviewed against your prescription, your frame and your intended use before glazing.

Scott’s Professional Advice

The coating should match the lens purpose.

A driving pair, screen pair, everyday pair and prescription sunglass do not all need the same coating conversation. The right coating depends on the job the glasses are doing.

Frequently asked questions

Is anti-reflection coating worth it?

Yes, for most everyday prescription glasses anti-reflection coating is worth having. It reduces distracting reflections, improves lens appearance and can make glasses feel more comfortable under artificial lighting and for night driving.

What does scratch-resistant coating do?

Scratch-resistant coating helps protect the lens surface from minor everyday wear. It does not make lenses scratch-proof, so proper cleaning and storage still matter.

Do I need blue light coating?

Blue light coating may feel more comfortable for some screen users, but it is not always necessary. If you have screen discomfort, first check your prescription, screen distance, dry eye, lighting and whether you need occupational lenses.

What is hydrophobic coating?

Hydrophobic coating is a water-repellent surface layer. It helps water bead and run off the lens more easily, which can make lenses easier to clean and manage in rain.

What is oleophobic coating?

Oleophobic coating helps repel oils, fingerprints and greasy smears. It is often part of an easy-clean lens coating.

Do clear prescription lenses have UV protection?

Some clear lens materials and coatings provide UV protection, but it depends on the specific lens. Sunglasses should always be chosen with proper UV protection, not just tint darkness.

Are premium lens coatings better?

Premium coatings can be better because they often combine improved anti-reflection, scratch resistance, water repellence and easier cleaning. They are most useful for glasses worn daily.

Can lens coatings peel?

Coatings can fail if lenses are exposed to heat, harsh chemicals, poor cleaning methods or long-term wear. Using proper lens care reduces the risk of coating damage.

What coating is best for night driving?

A good anti-reflection coating is usually the most useful coating for night driving because it reduces distracting reflections from headlights, street lights and dashboard lighting.

Which coating should I choose for everyday glasses?

For everyday clear glasses, anti-reflection with scratch-resistant and easy-clean properties is usually the best starting point. Additional options depend on your lifestyle and lens type.
