    If your vision has just turned blurry, check this first.<\/strong> Call your local emergency number or go to an emergency department now (and do not drive yourself) if the blur comes with a drooping face, weak arm, slurred speech, sudden severe eye pain with nausea, a dark curtain or shadow across your vision, or loss of sight in one eye.

Retinal causes are treated by Do\u00e7. Dr. Muhammet Derda \u00d6zer and Op. Dr. Aysan Bayram.<\/p><\/div><\/div><\/div><\/div><\/section>\n\n\n\n\n

    Blurred vision means that what you see has lost its sharpness, as if you were looking through a smeared window or out-of-focus camera lens.<\/strong> It is a symptom, not a diagnosis. The cause can sit in the front of the eye (the tear film, cornea or lens), in the retina and optic nerve at the back, or in the brain areas that process what the eyes see.<\/p>\n\t\t\t\t\t\t

    It helps to separate blur from other changes, because doctors ask about them differently:<\/p>\n
