Red eyes are a common problem that can affect one or both eyes at once. This condition occurs due to blood vessels on the surface of the eyeball, which expand due to infection or any irritant. Among the main reasons for going to the hospital, ophthalmologists named severe eye pain and a sharp deterioration in vision.
According to the Mayo Clinic, short periods of red eyes are usually nothing to worry about. What should be considered is a condition that doesn't go away within a few days, especially if it's accompanied by mucous or pus discharge.
Emergency care should be provided for red eyes when:
- vision deteriorates sharply;
- you experience a severe headache, eye pain, or unusual sensitivity to light;
- nausea and vomiting appear;
- sensation of a foreign object in the eye;
- swelling around the eyes;
- difficulty opening or keeping eyes open.
