Blurry vision can be caused by a variety of factors, including refractive errors, eye diseases, and temporary vision changes. Refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia, are the most common cause of blurry vision. These conditions occur when the shape of the eye does not properly focus light onto the retina, resulting in blurred or distorted vision. Refractive errors can typically be corrected with eyeglasses, contact lenses, or refractive surgery.
Other common causes of blurry vision include eye diseases such as cataracts, glaucoma, and age-related macular degeneration. Cataracts cause the lens of the eye to become cloudy, making it difficult to see clearly. Glaucoma is a condition in which pressure builds up inside the eye, damaging the optic nerve and causing vision loss. Age-related macular degeneration is a gradual decline in central vision that occurs as people get older. Additionally, some medications, such as antihistamines and decongestants, can cause temporary vision changes. In some cases, blurred vision can also be a sign of a serious underlying condition, such as a stroke or a brain tumor, so it is important to have an eye exam if you experience persistent blurred vision.
