Special glasses with red light to slow childhood nearsightedness

This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This trial is testing a new type of eyeglass lens that uses passive red-light emission to help slow down myopia (nearsightedness) in children. Researchers want to see if wearing these special glasses can keep kids' eyes from becoming more nearsighted over time. The study will compare how well the new red-light glasses work compared to regular glasses.

Myopia is becoming more common in children, and when it gets worse over time, it can lead to serious eye problems later in life. Researchers are exploring whether red light technology in glasses could be a simple, non-invasive way to help slow this progression and protect children's vision.

Do you qualify?

You likely qualify if…

you are between 6 and 10 years old
you have been diagnosed with myopia (nearsightedness) with a prescription strength between -0.75 and -5.00
you have mild astigmatism (no more than 2.50)
you are willing to wear the study glasses for more than 12 hours per day, at least 6 days per week
you are able and willing to visit the research center for follow-up appointments over 2 years
your eyes are otherwise healthy with no other vision problems

You likely don't qualify if…

you have any eye conditions like keratoconus or amblyopia (lazy eye)
you have certain systemic conditions like diabetes or Down syndrome that affect vision
you have had binocular vision problems (problems with how your eyes work together)
you have used specialized myopia control glasses or contact lenses in the past month
you are currently taking medications that affect pupil size or focusing ability

What participation looks like

You will wear the study glasses as your everyday glasses for 2 years. In the first year, you'll wear regular single-vision lenses with red-light technology in one eye and a standard lens in the other. In the second year, you'll switch to myopia control lenses with the same comparison. You'll visit the Essilor R&D Centre regularly for eye exams and measurements to track how well the glasses are working to slow myopia progression.
