What should you know about a bloodshot and itchy eye?

Itching with redness often fits an allergic response, especially when both eyes water and symptoms follow dust, pollen, cosmetics, or animal contact. Conjunctivitis can also cause redness, watering, crusting, or discharge and may spread between people depending on its cause. Dryness, smoke, chlorine, or rubbing can irritate the eye without infection. The pattern, duration, and presence of pain help separate these possibilities.

Wash your hands before touching the area and avoid rubbing, contact lenses, eye makeup, and shared towels while the eye is irritated. A cool clean compress may reduce itching. Rinse away a suspected irritant with clean water. Ask a pharmacist or clinician before using medicated drops, particularly if you wear contact lenses or have another eye condition. Do not use someone else's prescription drops.

Seek prompt medical care for moderate or severe eye pain, reduced or blurred vision, marked light sensitivity, injury, chemical exposure, a bulging eye, or severe headache with nausea. Contact lens wearers with a red eye should obtain same-day advice because corneal problems can progress quickly. Arrange a review if discharge persists, symptoms worsen, or redness does not settle.

Ask whether the pattern fits Allergic Conjunctivitis, Conjunctivitis, or another cause, whether you should stop contact lenses, and which drops are safe. Describe when itching began, whether one or both eyes are affected, the type of discharge, and any change in vision.
