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.
Bright Side collected 12 symptoms which are a reason to consult a doctor.
1. White spots on the cornea of the eye.
This is a fairly common phenomenon among people who wear contact lenses and may be a sign of a corneal infection. Even small eye injuries caused by wearing contact lenses can lead to such an infection and then to a corneral ulcer. People who wear lenses with an expired shelf life or daily contact lenses for a long time (including overnight) are particularly at risk.
2. A white circle around the iris of the eye.
Most often it’s a sign of aging, which isn’t a reason to worry. But if you’re far from retirement age, a white circle around the iris can signify high cholesterol and triglycerides levels, which often means an increased risk of a heart attack or stroke.
