From time to time, everyone experiences unpleasant sensations in their eyes. For most of us, a good rest and sound sleep are enough to restore vision, but there are also some signs that cannot be ignored.
8. Involuntary tears.
It sounds a little paradoxical, but involuntary tears can be a sign of a dry eye. Thus the eye tries to make up for the lack of moisture. This phenomenon is common among those who spend a lot of time at the computer or in front of the TV.
Has it suddenly become difficult to close one eye and control its lachrymation? This is a symptom of paralysis of the nerve, which controls the facial muscles. It can be a complication after a viral infection.
9. A small dark dot on a background of flickering wavy lines.
These symptoms may indicate poor cerebral circulation. Yet, as a rule, the dots appearing and disappearing from the visual field indicate the opacity (destruction) of the vitreous humor. The most common cause is the general aging of the body. However, people with metabolic disorders — diabetes, vascular disorders, and diet fans — are at risk.
10. Disappearing image in the visual field.
If from time to time you notice an image disappearing from certain areas of your visual field, this is a sign of an eye migraine.
It can be accompanied by headaches due to cerebral circulatory disorders. An eye migraine is harmless. There’s no precise explanation of its occurrence, and there are no methods of treatment.
11. Blurred vision.
Myopia isn’t the only reason for blurred vision: it can be a sign of diabetes. If, in addition to blurred vision, you notice glares and halos around the light sources, this may indicate cataracts — a partial or complete opacification of the lens of the eye.
12. Yellow eye whites.
Most often, the cause lies in the decrease in the functionality of the liver and bile ducts. Yellowness may become the main symptom of hepatitis.
