Swollen or dilated blood vessels are the most common cause of eye redness. The surface of the eye appears red or bloodshot as a result.
A red eye or eyes might have numerous reasons. Medical emergencies are among them. Some raise questions but are not an immediate emergency. There is no need to worry about many of them.
Eye pain or visual issues are frequently more worrisome than eye redness.
The enlarged blood vessels on the sclera, the white part of the eye, give bloodshot eyes their crimson appearance. Vessels may swell as a result of
dry eye
excessive sun exposure
other debris or dust in the eye
Allergies
Infection
Injury
Use soap and water to wash your hands.
Try using a gentle stream of warm, clean water to wash the object out of your eye. Use an eyecup or a small, spotless glass, and place it so that the rim rests on the bone beneath your eye socket.
Another method for removing a foreign object from your eye is to take a shower, hold your eyelid open, and direct a gently stream of warm water over your forehead into the affected eye.
It is preferable to take out your contact lenses if you wear them before or as you irrigate your eye with water. On occasion, a foreign object may become adhered to the lens's underside.
Simple irrigation won't be able to eliminate the thing.
The item is lodged inside the eye.
The individual with the object in the eye has unusual vision
More than 24 hours after the object has been removed, there is still pain, redness, or the sense that something is in the eye.
