Acquired brain injuries often cause light sensitivity also known as photophobia. There was a study done in 2017 that showed that 76% of the time the light sensitivity could be alleviated with a tint on prescription lenses. The most common tint used was a FL–41 tint. They come in a light, medium, and dark. The one we have is the medium FL-41. In case you or someone you know has a concussion with photophobia, we might be able to help them. The reference is listed below.
