Light Sensitivity after Brain Injury

Brain injury is often accompanied by increased light sensitivity and general inability to tolerate normal glare. The problem seems to be an inability of the brain to adjust to various levels of brightness. It is as if one had a radio and the volume control was broke and you could not make the adjustments you normally do to control loudness.

Selective filters, particularly amber filters are often used by brain injury patients. Post Trauma Vision Syndrome patients may experience improvement in light tolerance when treated for PTVS with neuro-optometric techniques.
