Why do my eyes always feel blurry?

Generally, eyes constantly feeling blurry may be caused by eye strain and fatigue, refractive errors, dry eye syndrome, keratitis, cataracts, and other factors. If discomfort occurs, timely medical attention is recommended. Detailed analysis is as follows:

1. Eye Strain and Fatigue

Staring at electronic screens, reading books, writing, or engaging in other activities requiring prolonged concentration can keep the eyes in a tense state for extended periods, leading to eye fatigue and blurred vision. It is important to use your eyes appropriately in daily life and take breaks by looking into the distance for a few minutes to relax the eye muscles.

2. Refractive Errors

Refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These conditions cause light to focus incorrectly on the retina, resulting in blurred vision. Patients may find distant or near objects unclear and need to correct their vision by wearing glasses or undergoing surgery. Regular vision check-ups are recommended, followed by wearing appropriate glasses or contact lenses based on the results. For severe refractive errors, treatments such as laser surgery may be considered.

3. Dry Eye Syndrome

Dry eye syndrome occurs due to insufficient tear production or excessive tear evaporation, leading to inadequate moisture on the eye surface, causing eye discomfort and blurred vision. Patients may experience symptoms such as dryness, foreign body sensation, and burning in the eyes, with severe cases leading to blurred vision. Treatment includes using artificial tears or eye drops to supplement tear production, maintaining suitable indoor humidity, and avoiding prolonged screen time.

4. Keratitis

Keratitis is caused by infection with pathogenic microorganisms, leading to inflammation of the corneal tissue and affecting vision. Symptoms may include eye pain, photophobia (light sensitivity), tearing, and blurred vision. Under a doctor's guidance, patients can use medications such as levofloxacin eye drops, acyclovir eye drops, or ganciclovir ophthalmic gel for treatment.

5. Cataracts

Cataracts occur due to clouding of the lens, preventing light from focusing properly on the retina and causing blurred vision. Patients may experience blurred vision when looking at both distant and nearby objects, with symptoms gradually worsening over time. Surgical treatment is the primary approach for cataracts, including procedures like phacoemulsification. After surgery, patients' vision can be improved.

In daily life, we should maintain good eye hygiene and habits, avoid prolonged eye use and excessive fatigue, to protect eye health.
