causes of bloodshot eyes
We've all experienced red, bloodshot eyes from time to time, affecting one or both eyes. Red eye is caused by swollen or dilated blood vessels on the sclera, the white outer surface of the eye. Red eyes can be accompanied by eye pain, itching, eye discharge, swollen eyes or visual disturbances such as blurry vision.In other cases, a red eye may cause no irritation at all.ne of the main culprits of red eye is over-wearing or not properly caring for your contact lenses, which can cause a build-up of irritating surface deposits and microbes on your eye. Red eyes while wearing contacts could be a sign of a serious eye infection, such as keratitis or fungal eye infections.
