Short-sightedness (myopia) in children is becoming more common, and there's growing interest in ways to slow it down — including a newer approach called repeated low-level red-light therapy. It's promising, but it's also still emerging, so it's worth understanding clearly. Here's a measured look.
Why slowing myopia matters
Myopia isn't just about needing glasses. The more short-sighted an eye becomes, the longer it grows — and higher levels of myopia carry a greater lifetime risk of eye problems later on. That's why the goal of myopia management isn't only clearer vision now, but slowing how far the short-sightedness progresses through childhood.
What red-light therapy involves
Repeated low-level red-light therapy (sometimes shortened to RLRL) uses a desktop device that a child looks into for a short session, usually twice a day, at home. The idea is that gentle red light may slow the eye's growth. Studies — largely from overseas — have reported encouraging results in slowing myopia progression.
It's one of several tools for managing myopia, alongside approaches like specialised spectacle and contact lenses and low-dose atropine drops.
What the evidence does and doesn't say
The early research is promising, but it's still a relatively new therapy: questions remain about the best long-term use, how lasting the effect is once treatment stops, and long-term safety. Reputable clinicians treat it as an option to consider carefully and monitor closely — not a guaranteed fix.
That's not a reason to dismiss it, but it is a reason to make the decision with a specialist who can weigh it up for your child specifically.
Is it right for your child?
The right approach depends on your child's age, how quickly their myopia is progressing, and your family's circumstances. Our optometrist Hannah Kang supports myopia management here, and we can talk through whether red-light therapy or another option makes sense.
