What NHS Vouchers Do and Don’t Cover for Myopia Control

If your child is under 16 (or under 19 and in full-time education), they’re automatically entitled to an NHS optical voucher toward glasses. Current voucher values range from £42.40 to £233.56, depending on the strength of the prescription. That voucher goes toward the base cost of the lens and frame, the same as it would for any pair of glasses. What it doesn’t cover is the myopia control element itself, the DIMS or HAL technology, the contact lens design, or the reshaping treatment, since that’s classed as a premium, private add-on rather than standard NHS provision. Check your eligibility on our NHS Vouchers page. In practice, that means the voucher reduces your bill rather than eliminating the private cost, exactly as covered in our Stellest lenses guide.

Spectacle Lens Costs: MiYOSMART vs Stellest

Both MiYOSMART (DIMS) and Stellest (HAL) are spectacle lens options, and pricing tends to be structured similarly: either a one-off cost for the lenses, or a monthly payment plan.

MiYOSMART lenses alone typically cost from around £250 to £350 a pair, with frames priced separately. Some opticians offer payment plans instead, around £25 a month, which usually includes a replacement pair each year or whenever the prescription changes.

Stellest lenses tend to be priced similarly when bought outright, with complete glasses (frame and lenses together) typically costing around £300 to £360. Several opticians also offer 6 to 12-month interest-free payment plans, from around £19 to £24 a month, the range our own Stellest lenses fall into.

Contact Lens Costs: MiSight

MiSight is a daily disposable contact lens, so the cost structure is different again, it’s an ongoing monthly cost rather than a one-off lens purchase. Most UK providers charge somewhere between £44 and £52 a month via direct debit, plus an initial fitting fee that ranges from £45 to £150 depending on what aftercare is included. Because MiSight lenses are replaced daily, the ongoing cost reflects lens replacement as well as the myopia control element.

Orthokeratology Costs

Ortho-k works differently again: instead of a monthly lens subscription, you’re typically paying for a custom-made pair of rigid lenses upfront, alongside an initial consultation. Expect the lenses themselves to cost anywhere from £250 to £500, plus a consultation fee of £60 to £150. Many providers also offer ongoing monthly plans instead, from around £45 to £53 a month, which usually bundle in aftercare, replacement lenses, and cleaning solution. Lost or damaged lenses are typically an extra cost on top, often £125 or more per lens.

What Affects Myopia Control Lenses Cost

A few things move the price more than the underlying lens technology does:

• Monthly plan vs one-off payment, plans spread the cost but can work out more expensive over a year or two than paying upfront, depending on the provider.
• What’s bundled in, some prices include eye tests, aftercare appointments, and replacement lenses; others charge for these separately.
• Frame choice, for spectacle lens options, your frame is priced on top of the lens cost.
• Provider and location, independent opticians and larger chains price identically specified plans differently, it’s worth comparing more than one before committing.

Myopia Control Lenses Cost: Our Advice

There isn’t a single “cheapest” option once you compare like-for-like, monthly plans, bundled aftercare, and frame costs all shift the real total differently for each family. Use the price ranges above as a starting point, then compare actual quotes from opticians near you, factoring in what’s included. Our guide to how myopia control lenses work covers how each option actually functions, and our Stellest lenses guide covers one family’s real, ongoing experience with the cost and the results.

How We Found Out About Stellest Lenses

Our optician suggested Stellest lenses at what was otherwise a normal eye test appointment. We hadn’t researched myopia control beforehand and didn’t know lenses like this existed until it came up in conversation. If you’re in the same position, that’s completely normal, this isn’t something most parents go in already knowing about. If you want the science behind how Stellest and similar lenses actually work, we’ve covered that separately in our guide to how myopia control lenses work.

What the Fitting Process Actually Involves

There’s no separate clinical procedure beyond a standard eye test. Our daughter’s Stellest lenses were fitted the same way any pair of glasses would be: measurements taken, prescription confirmed, frames chosen. The only real difference is the lens itself.

The Adjustment Period: What to Expect

The one thing we’d flag honestly: the outer edges of the lenses felt a bit dizzying at first. That settled within around three weeks as she got used to them. It’s worth knowing in advance so it doesn’t feel alarming if it happens, it’s a known adjustment, not a sign anything’s wrong.

What Stellest Lenses Cost, and How Vouchers Can Help

For us, Stellest lenses cost around £24 a month, though the exact figure depends on the frame and any extras you add. Because our daughter is under 16, she was eligible for an NHS optical voucher, which contributed toward the cost. We go into a full cost breakdown, including NHS voucher eligibility and how it compares with contact lens options, in a separate guide.

Do Stellest Lenses Work? Our Daughter’s Results So Far

Our daughter has now been wearing Stellest lenses for 18 months, with a check-up every six months. At her last check in July, her eyesight had improved slightly, and that was despite not wearing them consistently every day. We want to be honest about that rather than presenting it as guaranteed proof, clinical trials, not one family’s experience, are the real evidence for how well this works generally. But it’s a genuinely encouraging sign for us.

The One Thing That Actually Determines Whether It’s Worth It

If there’s one piece of advice we’d give another parent, it’s this: consistency is everything. Myopia control lenses only work if they’re actually worn, as close to full-time as possible. Skipping days, or only wearing them some of the time, undermines the whole point, and you’re still paying the monthly cost either way. It’s worth being firm with your child about wearing them, because the value is entirely tied to how consistently they’re worn.

Other Myopia Control Options Besides Stellest

Stellest is one option among several. DIMS lenses (Hoya’s MiYOSMART) work on a similar principle with a different lens design, and MiSight contact lenses achieve a comparable effect for children who’d rather avoid glasses altogether. We haven’t used these ourselves, so we can’t compare them from experience, but our guide to how myopia control lenses work covers how all of them function and the evidence behind each.

Why Standard Glasses Don’t Slow Myopia Progression

Ordinary single-vision lenses do a good job focusing light correctly on the central retina, where you actually look. But at the edges of your vision, they let light focus slightly behind the retina instead. Researchers believe this peripheral signal, called hyperopic defocus, is part of what tells a growing eye to keep elongating. Myopia control lenses all work on the same underlying principle, however different they look: shift that peripheral focus point to sit in front of the retina instead, and the growth signal seems to weaken.

Myopia Control Spectacle Lenses: DIMS and HAL Technology

Two spectacle lens designs currently lead the evidence base, and they take slightly different approaches to the same idea.

DIMS (Defocus Incorporated Multiple Segments), used in Hoya’s MiYOSMART lens, has a clear central zone for normal distance vision surrounded by 400 small segments in the lens periphery, each adding extra positive power.

HAL (Highly Aspherical Lenslets), used in Essilor’s Stellest lens, takes a denser approach: 1,021 aspherical lenslets arranged in 11 concentric rings around the central zone, with the defocus effect increasing further from the centre.

A two-year comparative study found both genuinely slow eye growth, and the difference between the two wasn’t statistically significant, so DIMS and HAL work comparably well. That’s actually useful to know: the choice between them tends to come down to things like cost, fit, and what your optician actually stocks, not one being clearly superior.

How MiSight Contact Lenses Work

For children (or parents) who’d rather avoid glasses, MiSight is a daily disposable contact lens using the same underlying principle in a different form: concentric rings alternating between your normal correction and a peripheral myopic-defocus zone. In long-term trials, MiSight slowed progression by around 50%, and children who stayed on the study showed no meaningful catch-up progression even six years in. It’s been available in the UK since 2020.

Orthokeratology: The Overnight Option

Orthokeratology (ortho-k) works completely differently from the other three. Instead of being worn during the day, rigid gas-permeable lenses are worn overnight, gently reshaping the cornea while you sleep, flattening it centrally and steepening it slightly at the mid-periphery. That reshaping does two things at once: it corrects vision for the following day without needing to wear anything, and it creates the same kind of peripheral myopic defocus signal as the other options.

Which Type of Myopia Control Is Right for Your Child?

All four options are working toward the same goal by different routes, and none of them is simply “better” in the abstract, it depends on your child’s age, prescription, and what they’ll actually wear consistently, since none of these work if they’re left in a drawer. Our guide to choosing a myopia control lens covers exactly that decision, including what things actually cost in the UK.

What Causes Myopia in Children: Four Key Risk Factors

Rates of childhood myopia have climbed steadily since the 1970s. Current projections suggest that by 2050, roughly half the world’s population could be short-sighted. That’s not just a story about more people needing glasses. Higher rates of myopia, especially high myopia, carry a greater long-term risk of serious eye conditions later in life.

Research points to four main contributors.

1. Genetics: One Cause of Myopia in Children

If one parent is myopic, a child is more likely to become myopic too. The risk rises further when both parents are short-sighted. Genetics isn’t the whole story, though. Two children with similar lifestyles and similar family backgrounds can have very different outcomes, because genetic susceptibility interacts with environment rather than acting alone.

2. Not Enough Time Outdoors

This is the factor researchers consistently point to as the single most protective one. Bright natural light appears to trigger a response in the retina that may help slow down the eye elongation that causes myopia. This effect looks strongest for preventing myopia from starting in the first place, rather than slowing it once it’s already present. Children who spend around two hours a day outdoors tend to have a meaningfully lower risk of developing myopia than those who don’t. The College of Optometrists’ evidence review covers the research behind this in more depth.

This matters practically: it’s less about restricting what children do indoors, and more about actively building outdoor time into the day.

3. Screen Time and Near Work

Screens get a lot of the blame, and there is a genuine association between heavy screen use and myopia risk. But the picture is more nuanced than “screens cause myopia.” Much of the effect seems to come from what screen time displaces, time spent outdoors. Add in the sheer amount of close-up focusing (near work) that reading, homework, and devices all involve, and the risk compounds. During COVID-19 lockdowns, when outdoor time dropped and screen time rose sharply worldwide, researchers observed faster myopia progression in children, a natural experiment that reinforced how closely these factors interact.

The practical takeaway isn’t necessarily “ban screens,” but rather balancing near work with regular breaks and outdoor time.

4. Urban Living and Environment

Children in cities tend to have higher rates of myopia than children in rural areas. This is likely down to a mix of reasons: less access to green space, more structured indoor schedules, and in some regions, long winters that limit outdoor time. None of these are things you can necessarily change, but they’re useful context if you’re wondering why myopia rates vary so much between areas.

What This Means for Parents

None of these risk factors guarantee a child will or won’t develop myopia, but knowing what causes myopia in children helps you spot it early, which matters. The earlier myopia starts, the faster it tends to progress, and the more valuable early monitoring becomes. Practical steps worth considering:

• Aim for regular outdoor time, ideally in the region of two hours a day
• Encourage breaks during long stretches of reading, homework, or screen use
• Book regular eye tests, especially if either parent is short-sighted
• If your optician confirms a prescription, ask specifically about myopia management options rather than only a standard pair of glasses

Next Steps

If your child has recently been diagnosed with myopia, or their prescription keeps increasing, it’s worth understanding what treatment options actually exist beyond a standard lens upgrade. Our guide to myopia control lenses covers spectacle lenses, contact lenses, and orthokeratology, and how to find an optician that offers them.

It’s the reason so many children end up needing their first pair of glasses. And it’s becoming more common every year, both in the UK and globally.

This guide covers what’s actually happening inside the eye, how to spot the signs in a child, and what typically happens next.

What’s Actually Happening in the Eye

To see clearly, light needs to focus precisely on the retina – the light-sensitive layer at the back of the eye. In a myopic eye, that light focuses just in front of the retina instead. This usually happens because the eyeball itself has grown slightly too long, from front to back. The result: objects in the distance look blurred, while close-up vision, like reading a book, stays sharp.

This is different from simply “needing glasses” in a generic sense. The physical length of the eye drives myopia, and that length can keep increasing as a child grows. That’s why myopia in children often gets worse over time rather than staying fixed.

Common Signs of Myopia in Children

Myopia usually first appears somewhere between the ages of six and thirteen, though it can start younger. Children often adapt surprisingly well to blurry vision without realising anything is wrong. That’s why it can go unnoticed for a while. Signs worth watching for include:

• Sitting very close to the TV, or wanting to sit near the front of the classroom
• Squinting to see things at a distance
• Holding books or tablets close to the face
• Complaining of headaches or tired eyes, particularly after school
• A teacher mentioning your child struggles to read the whiteboard

Children often don’t complain directly. That’s why regular eye tests matter more than waiting for symptoms to appear.

Is Myopia Common?

Very. Roughly a third of people in the UK have short-sightedness. Rates in children have been climbing for decades, and researchers expect that trend to continue. It’s worth knowing this isn’t unusual or alarming in itself, it’s simply become one of the most common reasons children need glasses.

What Happens Once Myopia Is Diagnosed

If an optician confirms your child has short-sightedness, glasses or contact lenses will correct their vision straight away. This lets them see clearly at a distance. Standard lenses don’t stop the underlying cause though, with the eye continuing to lengthen. That’s why many opticians will also discuss the rate of progression, and whether monitoring or a myopia management approach makes sense. The NHS page on short-sightedness has more detail on standard treatment and when to seek advice.

Next Steps

If your child has just received a diagnosis, two follow-up questions are worth exploring next. Why does myopia develop in the first place? And what can help slow it down once it’s present? Our guide on what causes myopia in children covers the genetic and lifestyle factors involved. Our guide to myopia control lenses explains the treatment options available in the UK, from specialist spectacle lenses to contact lenses and orthokeratology.
