Lifestyle timing and parent education drive myopia control

A 3 to 5 minute outdoor break after near work may do more for myopia control than two hours in the morning

Emerging insights from the Asia-Pacific Myopia Management Symposium (APMMS) highlight a shift in how we approach outdoor time for children at risk of myopia. In an interview, Prof. Maria Liu of the UC Berkeley School of Optometry emphasised that frequent, short outdoor breaks immediately following near-work activities may be significantly more effective than a single, prolonged outdoor session.

Liu said lifestyle guidance should focus not only on the total amount of outdoor exposure, but on when it happens around reading, homework and screen use. “What I want to emphasise, regarding the lifestyle change, is not so much on the total duration of outdoor exposure, but how it is delivered in conjunction with the near activities,” Liu said.

Animal models suggest outdoor breaks are most effective immediately after near work. Liu said each break should last at least three to five minutes and should involve looking at far distances across the full visual field. That approach, she said, may be more useful than a two-hour outdoor session in the morning followed by the rest of the day indoors.

Treatment development is also becoming more personalised. Liu said commercially available optical options include novel spectacles, daytime contact lenses and overnight contact lenses.

Research is now exploring whether optics can be customised to each child’s pupil behaviour and lifestyle, and whether dynamic signals can keep the retina from adapting to constant treatment cues.

The bigger challenge is translating research into real-world care. Liu said some parents hesitate to start myopia control until there is clear evidence that a child’s vision is worsening or the eye is elongating.

“But we know that the earlier the intervention, the better the long-term outcome,” Liu said.

The opposite problem is also growing as parents turn to ChatGPT and other AI tools for answers. Liu said parents may bring research papers or AI-generated responses into consultations but struggle to judge what is relevant to their child.

For clinicians, the task is to balance published evidence, AI-sourced information and professional judgement so myopia control is tailored to each case.
