Symptom - Nystagmus
Nystagmus is a condition that involves involuntary, rapid, repetitive movements of one or both eyes from side to side, up and down, or in a circular motion.
Vision can vary
Vision varies during the day and is likely to be affected by emotional and physical factors such as stress, tiredness, nervousness or unfamiliar surroundings. Nystagmus sufferers may tire easily than other people because of the extra effort involved in looking at things.
Print size
Many people with nystagmus can read very small print if it is close enough to their eyes. Some find a visual aid such as a magnifier helpful. However, large print material should always be made available and all written matter should be clear. It is very difficult to share a book because it will probably be too far away or at the wrong angle.
Reading speed
People with nystagmus may be slow readers because of the extra time needed to scan. This should not be taken as a sign of poor reading ability, but students or school children with nystagmus may need extra time studying and when sitting exams.
Using computers
Computers are used by many people with nystagmus, as they can position screens to suit their own needs and adjust brightness, character size, and so on. However, some people find it difficult to read computer screens for more than a few minutes.
Depth perception
Depth perception is usually considerably reduced. This may sometimes make people seem a little slower or clumsier than normal.
Balance
Balance may be affected, possibly because of poor depth perception, which may make it difficult to use stairs or cross uneven surfaces. Nystagmus is not painful and does not itself lead to blindness.
Care
Glasses and contact lenses do not correct nystagmus although they may help a little and should certainly be worn to correct other sight problems.
