Why Is There Sudden Bloodshot in the Corner of My Right Eye, But Not My Left?
When there is a sudden bloodshot in the corner of the right eye while the left eye is fine, it can be confusing and unsettling. This phenomenon can be caused by various reasons, such as eye fatigue, conjunctivitis, and more. To ensure eye health, it is recommended to seek medical attention promptly and follow the doctor's instructions for treatment and care.

1. Eye Fatigue: Staring at electronic devices like phones and computers for extended periods can cause eye strain, leading to bloodshot eyes. In this case, the eyes may also feel dry and uncomfortable. To alleviate this symptom, it is advisable to rest the eyes regularly, avoid staying up late, and reduce prolonged use of electronic devices. You can try closing your eyes to rest or gently massaging the area around the eyes to relieve discomfort.
2. Conjunctivitis: This condition is usually caused by bacterial infection, resulting in localized redness, swelling, pain in the eye mucosa, and may be accompanied by increased secretions. Treatment for conjunctivitis can include the use of antibiotic eye ointment or eye drops under a doctor's guidance, with common medications being Chloramphenicol Eye Ointment or Tobramycin Eye Drops. Oral antibiotics such as Amoxicillin or Cefixime are also commonly prescribed.
3. Other Causes: In some cases, allergic purpura or retinal vessel rupture and hemorrhage may also cause eye bloodshot. For allergic purpura, anti-allergic medications such as Loratadine Granules or Prednisolone Acetate Tablets can be taken as recommended by the doctor. For retinal vessel rupture and hemorrhage, professional ophthalmic treatment such as laser photocoagulation is required to stop the bleeding.
To protect eye health, it is recommended to develop good living habits, ensure sufficient sleep, and avoid staying up late for extended periods. Dietarily, consume more fresh fruits and vegetables, such as apples, bananas, pitaya, kiwi, celery, and spinach, to supplement the body's nutritional needs. These methods can effectively help restore eye health and reduce the occurrence of bloodshot eyes.
