Bloodshot eyes are due to swollen or dilated blood vessels, which cause the surface of the eye to look red, or bloodshot.
This may result from extremely dry air, sun exposure, dust, foreign body, an allergic reaction, infection, trauma, or other conditions
One common cause of a red eye is straining or coughing. This can lead to a bright red, uniformly dense bloody area on the sclera. This is called a subconjunctival hemorrhage. Although this bloody area may appear alarming, it is a fairly common occurrence and of little significance. If you notice a bloody blotch in one eye that doesn't hurt, but just looks bad, don't worry. It generally clears up on its own within a week or two.
