Redness in the eyes can be caused by various factors. The most common cause is eye strain, such as prolonged use of electronic devices or staying up late, which can lead to dilation of blood vessels in the eyes and result in redness. Other possible causes include allergic reactions, conjunctivitis, and dry eye syndrome, resulting from exposure to allergens, bacterial or viral infections, and eye dryness, respectively. Patients should ensure adequate rest, avoid prolonged eye use, and maintain sufficient sleep. For allergic conjunctivitis, antihistamine eye drops may be used; for infectious conjunctivitis, anti-infective treatment is required; and for dry eye syndrome, artificial tear eye drops can help. If symptoms persist or worsen, prompt medical consultation is recommended to receive professional diagnosis and treatment.
