Can a 13-Minute eye exercise routine ease screen strain?
NCT ID NCT07816419
First seen Sep 11, 2026 · Last updated Sep 17, 2026 · Updated 2 times
Summary
Researchers at King Saud University tested whether a four-week yogic eye exercise program reduces symptoms of computer vision syndrome in female university students. All 36 participants performed a 13-minute sequence of relaxation and eye-strengthening exercises three days a week for four weeks. They rated nine symptoms, including dry eyes, blurred vision, and neck or shoulder pain, before and after the program. The study had no control group, so every participant served as her own comparison.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a four-week yogic eye exercise program combining relaxation and eye-strengthening movements
- What this could lead to
- If the program helps, it could offer students a free, equipment-free way to ease eye strain and related neck, shoulder, and back pain from long screen use.
- What could go wrong
- The study has no control group, so symptom relief could come from time, rest, or placebo rather than the exercises. It is small and limited to female design students, so results may not apply to other people or screen-heavy jobs.
