What causes sensitivity to bright light in the eyes?
Under normal circumstances, sensitivity to bright light may be caused by prolonged eye use, dry eye syndrome, conjunctivitis, iriditis, or uveitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. Specific analyses are as follows:
1. Prolonged eye use: Reading or looking at mobile phones for extended periods without allowing the eyes sufficient rest can lead to eye fatigue, making them more sensitive to bright light. In such cases, following medical advice, appropriate eye massage may help relieve fatigue, and overuse of the eyes should be avoided.
2. Dry eye syndrome: Caused by insufficient tear secretion, excessive evaporation, or abnormal tear composition, this condition reduces ocular secretions and commonly causes symptoms such as dryness, foreign body sensation, burning, and photophobia. Patients may use sodium hyaluronate eye drops, Jinzhen eye drops, or fluorometholone eye drops as directed by a physician.
3. Conjunctivitis: Often caused by microbial infection or external irritation, this inflammation can make the eyes sensitive to light and may also cause itching and conjunctival congestion. Patients should use medications such as tobramycin eye drops, ofloxacin eye drops, or erythromycin tablets as prescribed.
4. Iriditis: Usually associated with infections or eye injuries, common symptoms include eye pain, decreased vision, and ocular congestion, along with photophobia. Patients should follow a doctor’s recommendations and use medications such as compound tropicamide eye drops, olopatadine hydrochloride eye drops, or fluorometholone eye drops.
5. Uveitis: Typically caused by infection, immune factors, or trauma, it often presents with redness, eye pain, and blurred vision, and may also result in photophobia. Patients must follow medical advice for drug treatment; commonly used medications include diclofenac sodium sustained-release tablets, dexamethasone acetate tablets, and indomethacin sustained-release capsules.
Maintaining good eye hygiene and avoiding rubbing the eyes with hands is important in daily life. Diet should avoid scallions, leeks, garlic, and similar foods, focusing instead on light meals to support eye recovery.
