Introduction
Sudden eye redness may be caused by eye strain, trauma, acute conjunctivitis, keratitis, glaucoma, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. In daily life, ensure adequate sleep, maintain emotional stability and an optimistic mindset, and avoid large mood swings. At the same time, practice good eye hygiene and avoid rubbing your eyes with your hands.
Under normal circumstances, sudden eye redness may be caused by factors such as eye strain, trauma, acute conjunctivitis, keratitis, or glaucoma. It is recommended to seek timely medical attention to determine the underlying cause and receive appropriate treatment under a doctor's guidance. Specific analyses are as follows:
1. Eye strain: Prolonged use of the eyes, such as reading or using mobile devices for extended periods, can lead to eye fatigue and result in redness. Avoid overuse of the eyes, maintain a balance between work and rest, and symptoms usually resolve after adequate rest.
2. Trauma: If the eye sustains an injury, sudden redness may occur, often accompanied by swelling and pain. In such cases, follow medical advice to apply cold compresses to the eye, which helps constrict capillaries and reduce swelling and pain.
3. Acute conjunctivitis: Often caused by infections or exposure to allergens, this condition develops rapidly and may present with sudden eye redness, along with symptoms such as itching, light sensitivity, and tearing. Patients should follow medical advice and may use medications such as chloramphenicol eye drops, ofloxacin eye drops, or erythromycin tablets.
4. Keratitis: Mainly caused by microbial infections, injuries, or physical and chemical irritants. Inflammation can lead to eye pain, redness, and swelling, possibly resulting in sudden eye redness. Treatment should be administered according to medical advice, including antiviral or antibiotic eye medications such as acyclovir eye drops, ganciclovir ophthalmic gel, or compound neomycin sulfate eye drops.
5. Glaucoma: May be related to genetic factors or trauma. If left untreated, increased intraocular pressure can cause eye redness, along with symptoms such as headache and vision loss. Patients should follow medical recommendations for medication, commonly including mannitol injection, prednisolone acetate eye drops, and betaxolol hydrochloride eye drops.
In daily life, ensure sufficient sleep, maintain emotional stability and a positive mindset, avoid excessive mood swings, and refrain from strenuous physical activity. Additionally, maintain good eye hygiene and avoid rubbing the eyes with hands.
