Introduction
Red eyes may be caused by eye strain, dry eyes, conjunctivitis, keratitis, glaucoma, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. In daily life, it is advisable to avoid prolonged eye use, drink plenty of warm water, maintain adequate sleep, and avoid staying up late, all of which are beneficial for recovery.

Redness in the eyes may be caused by factors such as eye strain, dry eyes, conjunctivitis, keratitis, or glaucoma. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Eye Strain

Prolonged reading or writing may lead to sustained tension in the eye muscles due to extended near-work, resulting in poor blood circulation and eye redness. It is advisable to take regular breaks—look into the distance for several minutes every 40 minutes—or use eye-protective screen settings to help reduce eye fatigue.

2. Dry Eyes

This condition may be related to dry environments or prolonged wearing of contact lenses. Dry air or contact lenses can draw moisture away from the eyes, causing ocular tissue congestion. Using a humidifier indoors can help maintain suitable humidity levels, and regularly replacing contact lenses may alleviate discomfort.

3. Conjunctivitis

Conjunctivitis may result from bacterial infection, ultraviolet exposure, or other factors. Common symptoms include redness, congestion, and increased eye discharge. Patients are advised to follow medical instructions and use medications such as ganciclovir eye drops, ofloxacin eye drops, or erythromycin tablets for treatment.

4. Keratitis

Keratitis may be associated with eye injuries, decreased immunity, or other causes. Local inflammation can easily lead to symptoms such as redness, pain, and tearing. Patients should follow medical advice and use medications such as methylprednisolone tablets, levofloxacin eye drops, or acyclovir eye drops.

5. Glaucoma

This is an eye disease caused by elevated intraocular pressure, usually due to genetic factors or improper medication use. Symptoms may include red eyes, blurred vision, and headaches. Patients are advised to use medications such as mannitol injection, travoprost eye drops, or timolol eye drops under a doctor's supervision to improve symptoms.

In daily life, it is recommended to avoid prolonged eye use, drink plenty of warm water, maintain sufficient sleep, and avoid staying up late, all of which are beneficial for recovery.

Is conjunctivitis the same as red eye, and is it contagious?
If red eyes are caused by allergic conjunctivitis or irritative conjunctivitis (such as from wind, sand, or chemical exposure), these types of conjunctivitis are not contagious. Allergic conjunctivitis is usually triggered by exposure to allergens like pollen or dust mites and is accompanied by itching. Irritative conjunctivitis results from external factors, and symptoms typically subside once the irritant is removed. Neither type can be transmitted through contact.
