What should you know about bloodshot eyes tired?

Long periods of reading or screen use can reduce blinking, allowing the eye surface to dry. Poor sleep may also make irritation feel stronger, especially in a room with air conditioning, smoke or dust. Itching suggests an allergic trigger, while sticky discharge or eyelid crusting can occur with conjunctivitis. Tiredness can coexist with another eye problem, so it should not be used to explain away pain or altered vision.

Rest your eyes, blink deliberately during screen work, and place a cool clean cloth over closed lids. Drink normally and reduce exposure to smoke, dust and direct airflow. Lubricating drops may help dryness; a pharmacist can advise on a suitable product. Remove contact lenses if the eye is red or uncomfortable. Avoid rubbing and replace eye makeup that may be old or contaminated.

Seek prompt assessment for pain, light sensitivity, a new change in vision, significant swelling, injury or chemical exposure. A contact-lens wearer with a red eye should obtain medical advice promptly. Get urgent help if symptoms become severe or worsen rapidly. Book a routine review when redness recurs, remains after rest, or is accompanied by repeated discharge.

Is dryness the main issue, or could allergy, infection or eyelid disease be involved? Are my screen habits or lenses contributing? Which drops are appropriate, and how long should I try them?
