A 2016 study projected that 49.8% of the world’s population could have myopia by 2050; it did not predict that half of all children would be affected. Myopia management aims to slow progression in suitable patients, with individual assessment and ongoing review.
The 2050 figure is a global projection
Holden and colleagues’ 2016 systematic review and modelling study estimated future myopia prevalence across the world population. Its 49.8% estimate is a modelled population outcome, not a diagnosis, a certainty or a child-specific forecast. The study also considered high myopia separately.
Clearer sight and slower progression are different goals
Myopia makes distant objects look blurred. The National Eye Institute explains refractive errors and the role of glasses or contact lenses in correcting focus.
International Myopia Institute clinical guidance describes individual treatment selection and monitoring. Options may include appropriate spectacle or contact-lens designs, orthokeratology or atropine eye drops, depending on the patient and clinician’s assessment. Results vary; treatment is not a guaranteed cure or a promise to prevent future eye disease.
Our article on children’s eye care and myopia management gives related background. The Myopia Prevention information site provides further topic-specific information.
Where overnight Ortho-K fits
Ortho-K temporarily changes the corneal shape using prescribed overnight lenses. Read our guide to overnight Ortho-K lenses and the Ortho-K Sydney service information before discussing suitability.
Contact lenses carry infection risks. Follow the prescribing clinician’s wear and cleaning instructions, use the recommended disinfecting solution and keep lenses away from water. CDC contact-lens hygiene guidance explains these precautions. Overnight wear should only follow the specific prescription.
Questions for a myopia review
Ask what has changed since the previous examination, what the proposed option is intended to achieve, what risks and costs apply, and when progress will be reviewed. Bring previous prescriptions and describe practical concerns about wearing or caring for lenses.
Frequently asked questions
Does the 2050 study say that half of children will have myopia?
No. Holden and colleagues projected 49.8% prevalence across the global population in 2050. It is a modelling estimate, not a child-specific forecast.
Is myopia management the same as correcting blurred distance vision?
No. Correction improves focus; myopia management aims to slow progression. An individual treatment plan may address both goals, with results checked over time.
Are overnight Ortho-K lenses suitable for everyone?
No. Suitability requires assessment. These lenses need prescribed care and follow-up, and contact-lens infection risks must be discussed before treatment.
