Red eye, also known as bloodshot eyes, is caused by the dilation of tiny blood vessels on the surface of the eye. It can be due to conditions like dust or pollen allergies, eye infections from bacteria or viruses, autoimmune disorders like rheumatoid arthritis, eye injuries from rubbing or chemicals, or underlying ocular conditions affecting the eyelids, conjunctiva, cornea, or iris. Symptoms include pain, watering, irritation, blurred vision, and discharge. Determining whether red eye is painful or painless helps identify potential causes like scleritis, glaucoma, uveitis, or conjunctivitis.
