Varifocal Glasses Guide: What Are They?

Varifocal (or progressive) lenses correct near, middle, and distance vision in one pair of glasses, no separate pair needed for reading.

Unlike old-style bifocals, there’s no visible line dividing the lens. Bifocals have a distinct ledge you can see, with an abrupt jump between distance and reading vision. Varifocals blend the different zones smoothly into one lens, which is part of why they look completely ordinary from the outside, but also why there’s a real adjustment period as your eyes learn where to look for each distance.

Not all varifocals are equal. Standard lenses have a narrower zone of clear vision and more distortion at the edges. Premium or personalised varifocals, built around your exact prescription and frame, give you a wider clear zone and far less peripheral blur. That’s the main reason prices swing so much between retailers and lens tiers.

Getting Used to Varifocals

The adjustment period is real, and it’s not just in your head. Expect some peripheral distortion at first, and a genuine need to move your head rather than your eyes to find the right part of the lens. It settles down, but give it a couple of weeks before judging whether they’re right for you.

Varifocals aren’t limited to glasses either, multifocal contact lenses work on the same principle and are worth asking about if you’d rather avoid glasses altogether. Lentiamo, reviewed here, sells both.

How Much Do Varifocals Actually Cost?

Lens tier and retailer both move the price a lot. We’ve covered the full breakdown in our how much do glasses cost in the UK guide, and a direct retailer comparison with varifocal options in Specsavers vs Vision Express vs Glasses Direct and Specscart vs Lentiamo.

Blue light glasses for students are a fixture on every back-to-university shopping list, marketed as a fix for digital eye strain, headaches and poor sleep during long study sessions. Before spending part of your student budget on a pair, it’s worth looking at what the actual clinical evidence says.

What the Evidence Shows About Blue Light Glasses for Students

The College of Optometrists has reviewed the research on blue light filtering lenses and found the clinical evidence doesn’t back up the marketing claims, there’s no good evidence that blue light glasses meaningfully reduce eye strain or improve sleep quality on their own.

What’s actually causing that dry, tired feeling during long laptop sessions is usually simple: digital eye strain. We blink roughly 50% less often when staring at a screen, which dries out the eyes, while holding a fixed focus for hours fatigues the eye muscles. That’s a blinking and focus problem, not a light-colour problem, which is why a tinted lens doesn’t fix it.

Free Alternatives That Actually Help

You don’t need to spend anything to protect your eyes during term time:

• The 20-20-20 rule – every 20 minutes, look at something 20 feet away for at least 20 seconds. It relaxes the eye muscles that screen use fatigues.
• Built-in night mode – most laptops and phones have a free “Night Shift” or blue light filter setting, which does much the same job as a paid coating.

If you already wear prescription frames and are wondering whether a permanent filter coating is worth adding, our guide on whether lens coatings are worth it covers that in more detail.

What’s Actually Worth Buying for Screen Fatigue

If you do want to spend on genuinely useful study desk upgrades, these do more for screen fatigue than blue light glasses for students ever will:

• Lubricating eye drops – preservative-free artificial tears directly treat the dryness screen staring causes.
• An ergonomic laptop stand – raising your screen to eye level reduces neck strain and stops you slouching forward into glare.

You’ve had the eye test, picked your frames, and then comes the question every optician asks: “Would you like to add our premium coating bundle?” Standing at the till watching the total climb, it’s a fair question are lens coatings worth it UK shoppers keep asking, or is this just a well-rehearsed upsell?

Looking at the real numbers behind how much glasses cost in the UK, coatings can quietly double your bill. The honest answer is that some of them genuinely earn their keep. Others don’t hold up well once you look past the marketing. Here’s the breakdown, coating by coating.

Which Lens Upgrades Actually Matter?

This guide looks at what each major coating does, who benefits from it, and which ones you can skip to save money.

1. Scratch-Resistant Coating (Hard Coat)

What it is

Most prescription lenses today are lightweight, impact-resistant plastic rather than glass. That’s safer and more comfortable, but plastic is also much softer and easy to scratch. A scratch-resistant coating, sometimes called a hard coat, is an ultra-thin lacquer layer baked onto both sides of the lens to resist that.

Is it worth it?

Pretty much non-negotiable. No coating makes plastic indestructible, but without a hard coat your lenses take damage from everyday things you’d never expect:

• Routine cleaning – dust particles or the wrong cloth will micro-scratch an uncoated lens over time.
• Cumulative haze – thousands of tiny scratches eventually blur your vision even when your prescription is spot on.

Most reputable retailers now build this into the base price. If you see it listed as an optional extra, it’s usually a sign you’re looking at a rock-bottom, no-frills deal -add it.

2. Anti-Reflective (Anti-Glare) Coating

What it is

Uncoated plastic lenses reflect around 8–10% of the light hitting them, creating distracting bounce-back. Anti-reflective (AR) coating lets more light pass through to your eye instead of glancing off the surface.

Is it worth it?

Yes, for almost everyone:

1. Night driving – cuts the starburst and halo effect from headlights and LED streetlights, which matters for comfortably meeting UK driving vision standards.
2. Screen work – reduces glare from monitors and office lighting during long hours at a desk.
3. How you look on camera – without it, lenses can look glossy and reflective on video calls or in photos.

One caveat: because AR coating sits on the outer surface, it needs a bit more care than standard lenses. If you already wear coated lenses, our guide on how to clean anti-reflective lenses without ruining them is worth a read. Two things worth keeping on hand:

• AR-safe lens cleaning spray – alcohol-free, so it won’t strip the coating
• Proper microfibre cloth – a lot gentler than whatever’s nearest to hand

3. Blue Light Filter Coating

What it is

This one gets marketed hard as an essential for the screen-heavy lifestyle. It’s built to selectively block or absorb the blue-violet light emitted by phones, laptops and tablets.

Is it worth it?

Honestly, probably not for most people – this is where marketing tends to outpace the science. Retailers often imply blue light causes lasting eye damage or significant strain, but the College of Optometrists has been clear that the clinical evidence doesn’t really back that up.

There are a couple of genuine minor upsides:

• Sleep – late-night screen use can suppress melatonin, and filtering blue light may help some people wind down.
• Comfort preference – some wearers just prefer the slightly warmer tint.

Before paying an extra £20–£50 at checkout, it’s worth trying your phone or laptop’s built-in “Night Shift” or blue light filter – free, and does roughly the same job for most people.

4. Coating Bundles: Which Tier Actually Makes Sense?

This is usually where the are lens coatings worth it UK question gets murkiest, because retailers rarely sell coatings individually – they’re bundled into tiers, and it’s easy to get talked into the top one. A rough guide:

• Basic tier – scratch-resistant only. Fine for a backup or spare pair.
• Mid-tier (the sweet spot) – scratch-resistant + anti-glare. Covers 90% of what most people actually need day to day.
• Premium tier – adds a hydrophobic (water-repellent) layer. Genuinely useful if you’re regularly dealing with UK rain or fogged-up lenses coming in from the cold.

Frequently Asked Questions

Final Verdict: Are Lens Coatings Worth It UK Buyers Should Pay For?

Don’t feel pressured into the most expensive bundle just because it’s on the menu, the blue light and anti-dust add-ons in particular are doing more for the retailer’s margin than for your eyes. For most UK buyers, a combined scratch-resistant and anti-glare coating gives you the real protection at a fair price, without paying extra for claims that don’t hold up.
