VISUAL PROBLEMS
There are many types of eye problems and visual disturbances. These include blurred vision, halos, blind spots, floaters, and other symptoms. Blurred vision is the loss of sharpness of vision and the inability to see small details. Blind spots (scotomas) are dark "holes" in the visual field in which nothing can be seen. For the most severe form of visual loss, see blindness.
