Generally, unexplained eye redness may be caused by factors such as lack of sleep, allergies, or conjunctivitis. Patients can receive symptomatic treatment based on the specific cause. The details are as follows:
1. Sleep deprivation
Prolonged sleep deprivation can negatively affect overall health and the eyes, possibly causing symptoms such as eye redness, swelling, and itching. It is recommended to apply a cold compress using a cold towel under medical guidance.
2. Allergies
If the eyes come into contact with allergens such as pollen, dust, or animal hair, an allergic reaction may occur, leading to symptoms like eye redness, swelling, and pain. It is recommended that patients take antiallergic medications such as cetirizine hydrochloride tablets or loratadine tablets under medical supervision, while also avoiding exposure to known allergens.
3. Conjunctivitis
Infection of the eyes by pathogenic microorganisms such as bacteria or viruses may lead to inflammation, which irritates the conjunctiva and causes symptoms including eye redness, swelling, and pain. It is recommended that patients use medications such as ganciclovir eye drops or ofloxacin eye drops under medical guidance, while also limiting eye strain and screen time.
Besides the three causes mentioned above, other conditions such as drug side effects, vitamin deficiencies, or keratitis may also contribute. Therefore, it is advisable for patients to seek timely medical evaluation and treatment.
