Dim Light Disease

"Dim light disease" is a misperception that results from abnormality
within the visual cortex of the brain. Symptoms (equal and bilateral)
are:

1. False perception of dimness of light; normally bright light (e.g.
the sun) is peceived as MUCH dimmer. The day sky at 12:00 noon can
appears as bright as a 4-watt night-lamp would appear to the normal
eye.

2. Ability to perceive color and images with greater clarity as light
dims; colors and images can are best perceived in the absense of light.
The brighter the light the less clear images and colors are seen.

Pretty terrifying disease!!! Especially the dimness!!!!!!!

 

Not to be confused with "dim wit disease"
