Red-eye is a general term used to describe red, irritated and bloodshot eyes.
The appearance of red-eye ranges in severity from a bright red that completely covers the sclera, to a few enlarged blood vessels that look like wiggly red or pink lines across the white of the eye.
Pain in the eye may be described as a burning, throbbing, aching, or stabbing sensation in or around the eye. It may also feel like you have a foreign object in your eye.
If the pain is severe, does not go away, or causes vision loss, seek medical attention immediately.
