§01Problem

Why myopia can't wait

Myopia is blurred distance vision caused by an eyeball that is longer than normal. Myopia that begins in childhood progresses rapidly until adolescence.

  • High myopia (≤ −6 D) multiplies the risk of retinal detachment and glaucoma.
  • If left uncontrolled, it can progress to −8 D, even −10 D.
  • Myopia that starts at an early age progresses for longer and faster.
  • Evidence-based treatments can slow progression by 30–60%.

§04Risk factors

Factors that accelerate myopia

Parental myopia

Two myopic parents raise a child's risk roughly sixfold.

≈6×risk increase

Screens & near work

More than 4 hours of sustained near work a day — screens, tablets, books — is associated with faster progression.

≥4 hnear work

Insufficient outdoor time

Less than 2 hours outdoors per day markedly increases myopia risk.

< 2 hrisk threshold

Early onset age

Myopia starting at age 6–8 carries a risk of becoming high myopia by age 18.

§05Who it's for

Clinician and parent, on the same chart

The clinician measures and decides; the parent follows along on the same chart. Reports are shared with a single link.

If you're a clinician

  • Record measurements in seconds during the exam
  • Track the progression rate and BHVI prognosis automatically
  • Share the report with the parent via a single link

If you're a parent

  • See your child's measurements and progression chart
  • Access the report and treatment plan your clinician shares
  • Keep up with appointments and check-ups

§06FAQ

Frequently asked

What is MiyoLab?

MiyoLab is a clinical management platform built to scientifically track childhood myopia (nearsightedness). It offers measurement tracking, prognosis with the BHVI methodology and treatment comparison for clinicians.

How is myopia tracked in children?

The child's periodic refraction (SPH/CYL/AX) and axial length measurements are recorded on the platform; the system automatically computes the progression rate and BHVI prognosis. Treatment decisions are thus tracked within a structured myopia control program.

Is MiyoLab free?

Yes, creating an account and using the tracking features is free. You can register as a clinician or a patient/parent; no installation required, it runs in your browser.

What is the BHVI prognosis?

The Brien Holden Vision Institute (BHVI) methodology estimates the child's refraction at ages 18 and 21 and the likelihood of high myopia, based on current measurements.

Which treatments can I compare?

You can compare, side by side on a chart, the effect on progression of evidence-based treatments such as low-dose atropine, orthokeratology (Ortho-K), MiSight contact lenses and DIMS spectacle lenses.

Is my data safe?

All data is transmitted over an encrypted connection and processed under KVKK, Türkiye's data-protection law. Only the authorized clinician and the relevant patient/parent can access patient records.
