Photophobia

Photophobia can be described as a symptom of abnormal physical intolerance to the visual perception of light. As a medical symptom, photophobia is not a morbid fear or psychological phobia, but an experience of discomfort or pain to the eyes due to light exposure or by presence of actual physical sensitivity of the eyes.

In terms of hallucinogen usage, this component is usually triggered by the way in which substance induced pupil dilation disables the eye's ability to adjust itself accordingly depending on current levels of light exposure.
