When Myopia Keeps Progressing, What Worries Parents Most?
“I’m not afraid of my kid wearing glasses. I’m afraid of the prescription getting worse every year and feeling like there’s nothing we can do about it.”
That’s the sentence we hear most often at Beyond Visual Optometry. And your worry is well-founded.
Myopia is fundamentally the eyeball growing too long (axial elongation) — and once the eye elongates, it cannot shrink back. High myopia (worse than -6.00D) carries a 5–10 times higher lifetime risk of retinal detachment, macular degeneration, and glaucoma compared to a normal eye. Tracking your child’s prescription trend early is the first step in protecting their vision.
Childhood Myopia in Taiwan: The Numbers
Taiwan has one of the highest myopia prevalence rates in the world:
- First grade of elementary school: roughly 5–10% myopic
- End of elementary school (sixth grade): roughly 55–65%
- High school graduation: over 85%
- High myopia prevalence (adults): roughly 20–25%
Myopia progresses fastest between ages 8 and 14. Intervening during this golden window produces the most significant results.
Why Does Myopia Keep Progressing?
The root cause of myopia is an excessively long eye axis — the eyeball’s front-to-back length exceeds normal, so light focuses in front of the retina instead of on it.
Three main drivers of continued axial elongation:
- Too much near work: More than 3–4 hours daily on phones, books, or tablets keeps the ciliary muscles chronically contracted, stimulating axial growth
- Not enough outdoor time: Natural light (above 10,000 lux) is associated with dopamine release, and research has observed a relationship between outdoor time and axial development. Two hours of outdoor activity per day is a common recommendation in the ophthalmology community
- No regular tracking: If you don’t know whether the eye axis is lengthening, you can’t adjust the lens strategy at the right time
Optometrist vs. Ophthalmologist: Who Does What
Many parents are confused about who should handle their child’s myopia. Here’s the correct division of roles under Taiwanese regulations:
| Service | Licensed Optometrist (Beyond Visual — YoYo) | Ophthalmologist (MD) |
|---|---|---|
| Vision and prescription assessment | ✅ | ✅ |
| Axial length measurement | ✅ | ✅ |
| Myopia-control lens fitting (MiSight, Zeiss MyoCare) | ✅ | ✅ |
| Regular tracking records and trend analysis | ✅ | ✅ |
| Low-dose atropine prescription | ❌ Requires a physician’s prescription | ✅ |
| Fundus examination, cycloplegic refraction | ❌ Classified as medical procedures | ✅ |
Beyond Visual Optometry’s role is regular measurement, record-keeping and tracking, and myopia-control lens fitting. Children who need medication are referred to an ophthalmologist — it’s a collaboration, not a turf war.
Myopia-Control Lenses: What an Optometrist Can Do
Peripheral-defocus lenses, supported by substantial international clinical research, are the tools that licensed optometrists can fit and track:
| Lens | Type | Recommended Age | Clinical Research Results | Best For |
|---|---|---|---|---|
| MiSight daily disposables | Contact lenses | 8 and up | Axial elongation slowed by about 52% | Active kids who are comfortable with contact lenses |
| Zeiss MyoCare | Spectacle lenses | 6 and up | 12-month study: myopia progression slowed ~48%, axial elongation ~41% | Kids who won’t wear contact lenses |
The figures above are averages from international clinical studies. Individual results vary with visual habits, genetics, and compliance.
Option 1: MiSight Daily Disposable Contact Lenses
What Is MiSight?
MiSight, made by CooperVision, is the world’s first daily disposable contact lens with an FDA-approved myopia-control defocus design.
It uses a dual-focus optical design: the central zone corrects refractive error, while the peripheral zones use a special defocus structure — giving children clear, natural vision quality.
Clinical Research Notes
- In a 3-year clinical study, the MiSight group’s axial length measurements differed from the control group
- Ask your optometrist for the detailed study data; individual results vary
Who It Suits
- Children aged 8 and up who can handle contact lenses on their own
- Families willing to follow the daily hygiene routine
- Highly active kids who don’t want to wear glasses all day
Option 2: Zeiss MyoCare Spectacle Lenses
What Is MyoCare?
Zeiss MyoCare is a spectacle-lens form of myopia-management lens using C.A.R.E.® technology (Cylindrical Annular Refractive Elements) — nearly invisible concentric rings that alternate defocus and correction zones across the lens, giving the child clear vision while creating a competitive defocus signal that helps slow axial elongation.
No contact lenses required, so acceptance among children is high, and daily care is the same as ordinary glasses. The portfolio also includes MyoCare S, designed for younger children with faster-progressing myopia.
Clinical Data
Zeiss’s 12-month clinical study in Asian children showed MyoCare slowed myopia progression by about 48% and axial elongation by about 41% on average (MyoCare S: about 45% and 34%). These are study averages; real-world results vary with a child’s visual habits, genetics, and compliance, and require regular follow-up.
Who It Suits
- Children who refuse to wear contact lenses
- Younger children (6 and up; MyoCare S for faster progressors)
- Parents who want something simple to use and easy to maintain
The Real Key: A Solution Your Child Will Actually Stick With
Even the best lens does nothing if your child won’t wear it.
What Beyond Visual Optometry cares about most is not recommending the most expensive option, but finding the combination your child will genuinely cooperate with and your family can sustain.
Choosing a Frame (for the Spectacle Option)
For children’s frames, the key isn’t the brand — it’s:
- Light and snug: silicone nose pads that don’t press on the nose bridge
- Doesn’t slip: temple curvature that fits your child’s face
- Drop- and impact-resistant: memory-material frames that hold their shape through daily use
- Correct sizing: oversized frames increase optical-center alignment error and reduce effectiveness
The Regular Tracking Routine
- Measure axial length every 3–6 months
- Axial length change is the true objective indicator — it reflects eye development better than prescription numbers alone
- Adjust the plan based on tracking results; this is an ongoing program, not a one-time fitting
FAQ
Q: At what age should tracking start?
The earlier the better. The fastest-progression window is ages 6–14. For children aged 6 and up whose myopia increases by more than 0.50D per year, regular tracking is recommended. The younger you start, the more complete a picture you’ll have of axial development.
Q: Do we still need to see an ophthalmologist?
We recommend doing both. The optometrist handles lens fitting and regular tracking; the ophthalmologist handles fundus health checks and medication evaluation (such as low-dose atropine). The two roles don’t conflict — together they give your child the most complete care.
Q: How long does myopia tracking continue?
Generally until age 18–20, when axial development stabilizes. It’s not something you do for a few years and stop — the goal is continuous tracking through the growth years so your child’s prescription at 18 is as low as possible.
Q: My child is already at -5.00D. Is tracking still worth it?
Absolutely. The goal of tracking is to slow progression, not reverse it. With myopia-control lenses and regular evaluation, a child might reach 18 at -6.00D instead of continuing past -8.00D. Every diopter avoided lowers the future risk of retinal complications.
Q: Where can I get children’s myopia tracking in Xinzhuang?
Beyond Visual Optometry’s Xinzhuang store is our primary location for children’s myopia tracking, offering axial length measurement, prescription trend records, MiSight daily disposable fitting, and Zeiss MyoCare evaluation. Optometrist YoYo (licensed optometrist) tracks progress every 3–6 months, and children who need medication evaluation are referred to an ophthalmologist. Call +886-2-2206-6700 or book online.
