Blurred eyes may be caused by overuse of eyes, keratitis, refractive error, lens clouding, vitreous lesion, retinopathy and other reasons.
1. Excessive use of eyes: excessive use of eyes due to prolonged gazing at cell phones and other electronic products, frequent rubbing of the eyes, and prolonged use of eyes in dim or bright light environments can lead to blurred eyes due to eye fatigue.
2. Keratitis: Bacterial and viral infection of the cornea leads to acute inflammation of the cornea, and the refractive and transmissive functions of the cornea are affected, resulting in blurred eyes.
3. Refractive error: improper eye use and other factors lead to refractive dysfunction of the cornea, lens, myopia, hyperopia, astigmatism and other diseases, light can not be accurately converged in the retina imaging leads to blurred eyes.
4. Lens clouding: aging, malnutrition, endocrine disorders, trauma and other factors lead to lens clouding, light through the lens is partially blocked, so the symptoms of blurred eyes.
5. Vitreoretinopathy: trauma, inflammation, diabetes and other factors lead to vitreous blood, vitreous clouding, vitreous mechanization and other changes, resulting in light transmission obstacles, manifested as blurred eyes.
6. Retinopathy: macular degeneration, retinal detachment, diabetic retinopathy and other causes lead to retinal pigment, nerve cell dysfunction, manifested as blurred eyes.
In addition, blurred eyes may also be glaucoma, eye tumors and other factors, blurred vision, it is recommended to consult a doctor in a timely manner, after a clear diagnosis and standardized treatment in accordance with medical advice.
