Introduction
Red eyes may be caused by factors such as eye strain, improper diet, dry eye syndrome, conjunctivitis, or keratitis. To prevent this, reduce prolonged use of electronic screens, avoid consuming excessive spicy or heat-inducing foods, maintain adequate eye moisture, practice good eye hygiene, and take precautions to avoid infections such as conjunctivitis and keratitis.
Under normal circumstances, persistent eye redness may be caused by factors such as eye strain, improper diet, dry eye syndrome, conjunctivitis, or keratitis. When experiencing physical discomfort, follow the doctor's advice for treatment. Specific analysis is as follows:
1. Eye strain
Excessive use of electronic devices such as smartphones and computers, or frequent late-night hours, can lead to eye fatigue. This fatigue impairs ocular blood circulation, causing congestion of blood vessels in the eyes and resulting in redness. Symptoms may include dryness, tiredness, and blurred vision. Adequate rest, along with applying a warm compress to the eyes for 15 minutes, can help improve blood circulation and relieve eye muscle fatigue.
2. Improper diet
Consuming excessive amounts of heat-inducing foods such as chili peppers and ginger may disrupt the body's yin-yang balance, leading to dilation of blood vessels in the eyes and causing redness. This may be accompanied by symptoms such as dry mouth, bad breath, and constipation. It is advisable to adjust dietary habits and reduce intake of spicy foods.
3. Dry eye syndrome
Insufficient tear production or excessive tear evaporation causes dry eyes, making them more susceptible to external irritation and resulting in redness. Other symptoms may include dryness, foreign body sensation, and light sensitivity. Treatment may include using sodium hyaluronate eye drops, polyvinyl alcohol eye drops, or hypersaccharide eye drops under medical guidance.
4. Conjunctivitis
Inflammation of the conjunctiva caused by viruses, bacteria, or allergies leads to irritation and vascular congestion in the conjunctival tissue, causing red eyes. Common accompanying symptoms include increased eye discharge, photophobia, and tearing. Follow medical advice to use medications such as levofloxacin hydrochloride eye drops, tobramycin eye drops, or ganciclovir eye drops.
5. Keratitis
Corneal inflammation caused by bacterial, viral, or fungal infections results in eye redness due to inflammatory stimulation of corneal tissues. Additional symptoms may include decreased vision and photophobia. Follow the doctor’s recommendations for treatment with medications such as fluconazole eye drops, acyclovir eye drops, or chondroitin sulfate eye drops.
Maintain good eye hygiene practices, adopt healthy visual habits, eat a balanced diet, keep eyes adequately moist, and maintain proper eye cleanliness to prevent infections such as conjunctivitis and keratitis.
