Myopia Control for Children in Seoul: Glasses vs Ortho-K vs Low-Dose Atropine

CHILDHOOD MYOPIA · SEOUL PARENT GUIDE

Which is better for a child: myopia-control glasses, Ortho-K or atropine?

Parents often ask whether myopia-control spectacle lenses, overnight orthokeratology (Ortho-K) or low-dose atropine is the “best” treatment. The evidence does not support one universal winner. Each option can slow myopia progression for some children, but the right choice depends on age, current prescription, rate of change, axial length, eye health, daily routine and how reliably the child can follow the plan.

Key takeaway: Myopia control is a long-term eye-growth plan. The most important step is measuring progression accurately, then choosing a treatment your child can use consistently and safely.

At NuneHIM Eye Center in Guro, Seoul, Dr. Daniel Jinhag Baik—a Korean-American ophthalmologist fluent in English and Korean—reviews these factors with families from Guro, Gasan, Geumcheon, Yeongdeungpo, Dongjak, Gwanak and nearby areas.

Why childhood myopia needs monitoring

Myopia means that light focuses in front of the retina when the eye is relaxed. In children, progression is often linked to the eye becoming longer from front to back, a measurement called axial length. A stronger prescription is only one visible sign; an eye can continue to elongate even when the glasses prescription appears stable for a short period.

Higher levels of myopia are associated with greater lifetime risk of retinal disease, myopic maculopathy, retinal detachment and glaucoma. That does not mean a child with myopia will develop these conditions. It means that slowing excessive eye growth early is a reasonable preventive goal.

Earlier onset, rapid change, strong family history, limited outdoor time and long periods of close work can increase concern. These factors should guide follow-up, but no single number decides treatment by itself.

Three options at a glance

Results from different studies cannot be used to rank these treatments directly. Study populations, follow-up periods, products, doses and adherence differ.

1. Myopia-control spectacle lenses: DIMS, HAL and similar designs

Myopia-control spectacles look like ordinary glasses, but the lens includes a specific optical design intended to reduce the signal that encourages axial elongation. DIMS uses multiple segments around the central correction. HAL uses highly aspherical lenslets. Other products use different designs, so the product name and clinical evidence matter.

In a two-year randomized trial, DIMS lenses reduced myopia progression and axial elongation compared with single-vision lenses. A separate randomized trial found that HAL lenses slowed progression and eye growth, with better results among children who wore them for more hours. These findings show that specially designed lenses can work; they do not guarantee the same result for every child or every “myopia-control” lens sold online.

What makes spectacles a sensible first option? They are non-invasive, easy to remove and usually simpler to keep hygienic than contact lenses. The frame must sit correctly, the pupils should align with the intended optical zones, and the child needs to wear the glasses for the recommended part of the day. A lens that stays in the case cannot control myopia.

When comparing products, ask who made the lens, which design was studied, whether the product is officially distributed in Korea, how the prescription and fitting are checked, and what follow-up is included. Price alone is not evidence of effectiveness.

2. Ortho-K (dream lenses): useful freedom, serious hygiene responsibilities

Ortho-K lenses are custom-fitted, oxygen-permeable rigid lenses worn during sleep. They temporarily change the corneal surface so that many children have clearer unaided vision during the day. The optical change may also slow axial elongation.

Systematic reviews and the International Myopia Institute describe meaningful average slowing of axial growth in children using overnight orthokeratology, but response varies. The child’s prescription, corneal shape, pupil size, lens design, wear time and follow-up all matter.

Ortho-K is appealing for children who play football, basketball or swim, or who strongly dislike wearing glasses during the day. It is only a good option when the child and family can follow the cleaning routine every night.

Never rinse Ortho-K lenses with tap water. Wash and dry hands before handling, use the prescribed solution, keep the case clean, and follow the clinic’s replacement schedule. Do not swim or shower while wearing lenses. A child who cannot reliably follow these rules may be safer with spectacles or another approach.

Remove the lens and contact an eye clinic urgently for pain, marked redness, strong light sensitivity, discharge, a white spot on the cornea or a sudden drop in vision. These symptoms can signal a corneal infection and should not be watched at home.

3. Low-dose atropine: an individualized medicine plan

Low-dose atropine is usually prescribed as a once-daily drop. Studies have evaluated concentrations including 0.01%, 0.025% and 0.05%. In the LAMP randomized trial, higher concentrations generally slowed progression more than 0.01%, while light sensitivity and near-vision symptoms were more common at higher concentrations. A US randomized trial found that 0.01% did not significantly slow progression compared with placebo in that study population.

These results do not mean that one concentration is right for every child. Prescribing rules and pharmacy availability differ by country, and some low-dose uses are off-label. The ophthalmologist should consider age, progression rate, pupil size, accommodation, allergies, concentration availability and whether another treatment is already being used.

Atropine may cause larger pupils, glare in bright light, temporary near blur or irritation. Some children show faster progression after treatment is stopped, so stopping or changing drops should be planned with follow-up rather than done abruptly without advice.

Can treatments be combined?

Combination treatment is not automatically better. The strongest randomized evidence for combination therapy is for Ortho-K plus 0.01% atropine, which produced a modest additional reduction in axial elongation over Ortho-K alone in several two-year trials. Combination treatment may be considered when progression remains faster than expected, but the extra burden, side effects and cost must be weighed.

For spectacle lenses plus atropine, encouraging observational data exist, but evidence is less definitive than for Ortho-K plus atropine. First confirm that the original treatment is being used correctly and that measurements are reliable.

What should be checked before choosing?

Many children are reviewed every three to six months, but the interval should reflect age, treatment, symptoms and progression speed. The goal is to compare reliable measurements over time—not to react to one isolated prescription change.

How families can choose in practice

1. Confirm progression risk. Review the child’s past prescriptions, age at onset, family history, outdoor time and close-work habits.
2. Measure more than visual acuity. Ask whether cycloplegic refraction and axial length are appropriate, and add corneal mapping if Ortho-K is being considered.
3. Match treatment to real life. A child who will wear glasses consistently may do better with spectacles than with a lens routine they cannot maintain.
4. Set a review date. Agree on what will be measured and when the plan will be adjusted.
5. Support healthy habits. Aim for regular outdoor time, comfortable working distance, breaks during close work and good sleep. Lifestyle supports treatment; it does not replace monitoring when myopia is progressing.

FAQ for Seoul parents

Are myopia-control glasses worth the cost?

Some specific designs have randomized-trial evidence. Choose based on documented design, correct fitting, expected wear time and follow-up—not a high price tag or a generic label.

Is Ortho-K more effective than glasses?

Both have evidence of slowing progression, but trials do not prove a universal winner. The safest practical choice depends on corneal suitability, hygiene, comfort, sport and adherence.

Is 0.01% atropine always enough?

No. Concentration affects both effect and side effects, and study results vary. The prescribing clinician should individualize the plan and monitor response.

Can a child stop treatment when the prescription is stable?

Do not stop without a review. Eye growth and prescription can change at different speeds, and some treatments need a planned taper or continued observation.

How much outdoor time should a child have?

Regular outdoor time is associated with a lower risk of developing myopia and is a useful part of prevention. It should complement, rather than replace, treatment and follow-up when myopia is already progressing.

When is an Ortho-K problem urgent?

Remove the lens and seek urgent eye care for pain, significant redness, light sensitivity, discharge, a corneal white spot or sudden vision loss.

Dr. Daniel Baik’s perspective

“The goal is not to choose the most expensive lens or the strongest treatment. It is to measure eye growth accurately, select an option that fits the child’s daily life, and follow the response carefully.”

If you are comparing myopia-control glasses, Ortho-K or low-dose atropine for your child, bring previous prescriptions and any lens or medication records to the appointment. NuneHIM Eye Center provides English-friendly consultations in Seoul.
