Narrow-angle glaucoma puts sudden and intense pressure on the lens of
the left eye. Symptoms are:

1. Visual distortion; 2-D images appear 3-D; visual hallucinations
2. Loss of image perception
3. Loss of color perception
4. Intense aching pain in that lens due to protein starvation
5. Sudden and complete blindess; subject cannot tell even dark or
light!; the description is usualy "seeing nothing at all", no light, no
darkness. Just totaly blank. Wierd feeling!
