Summary

This study tests whether daily training with colored lights can reduce light sensitivity in people who have had a traumatic brain injury. Twenty participants will use a device at home for 20 minutes a day, first with a blue light and then with a red light, or vice versa. Researchers will measure pupil responses and symptoms every 6 weeks to see if one color works better.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: fixation training with colored light targets
What this could lead to: If it works, this could provide a simple, at-home method to reduce light sensitivity after a head injury.
What could go wrong: This is a very small early study with only 20 participants, so results may not apply to everyone. The treatment is behavioral and may not work better than a placebo.
