Double Vision |
|
If the two eyes
are misaligned and aim at different targets, two
non-matching images will be sent to the viewer's brain. When
the brain accepts and uses two non-matching images at the
same time, double vision results. |
|
|
|
|
Double vision is
dangerous to survival, so, the brain naturally guards
against its occurrence. In an attempt to avoid double
vision, the brain will eventually disregard one of the
mismatching images. That is, the brain will ignore one eye
(called suppression). |
|
|
|
Due to the
brain's ability to suppress one eye, a person's double
vision can appear to go away without medical evaluation or
treatment. Bear in mind that the causes of the double vision
are very likely still present and that loss of vision in one
eye has probably occurred due to lack of treatment. When
vision in one eye is lost, the person has also lost normal
depth perception and stereo vision. However, the loss of
vision could be temporary and treatable. |

Redness of the Eye |
|
Bloodshot eyes;
Red eyes; Scleral injection; Conjunctival injection. Red
eyes are caused by enlarged, dilated blood vessels leading
to the appearance of redness on the surface of the eye. |
|
|
|
There are many
possible causes of a red eye or eyes. Some are cause for
concern, some are medical emergencies. Others are of no
consequence or concern at all. The degree of redness or
appearance of blood usually does not correlate to how
serious the situation is. It is generally more important
whether you also have eye pain or impaired vision. |
