New lens design aims to stop nearsightedness before it starts in children
NCT ID NCT07682974
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This trial investigates whether a new type of eyeglass lens, called a With-the-Rule Astigmatic Defocus Lens, can prevent the development of myopia (nearsightedness) in children aged 6 to 9 who have low hyperopia (farsightedness). The lens creates a 'defocus' signal around the retina, which may slow eye growth and delay or prevent myopia. The study compares two versions of this lens to a standard single-vision lens over two years, measuring changes in eye length and refractive error.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- With-the-Rule Astigmatic Defocus Lens
- What this could lead to
- If effective, this lens could offer a simple, non-invasive way to delay or prevent the onset of myopia in at-risk children, reducing the need for glasses or contacts later.
- What could go wrong
- This is an early-stage study with a small number of participants, so results may not apply broadly. The lens may not prevent myopia or could cause discomfort or visual side effects.
