Probiotic MR-61: a gut feeling against myopia?

This study tests whether a probiotic called MR-61 can help slow the worsening of nearsightedness (myopia) in children and teens aged 3 to 18. Participants will take either the probiotic or a placebo daily for a period, and researchers will measure changes in their vision and eye length. The goal is to see if this simple supplement can reduce the need for stronger glasses over time.
