Blurry vision, a condition in which you see objects out of focus, can have many causes, ranging from tired or irritated eyes to minor anatomical problems to serious health issues that may worsen or even lead to blindness if left untreated. The treatment and prognosis for blurry vision depend on the underlying cause.e60dc2a1-f33c-4a05-9b50-8e3e8e59762958b495c8-75ae-4fe7-8914-19ec46ed01ad
Possible Causes of Blurry Vision Causes Causes of blurry vision can be directly related to eye health — including refractive and nonrefractive errors — or caused by other illness or injury-related causes. It can be one of the earliest symptoms of diabetes. Refractive Errors Refractive errors occur when the eye is misshapen, which causes light to be focused improperly. These include: Nearsightedness (myopia) Farsightedness (hyperopia) Astigmatism , or imperfect curvature of the cornea (lens) of your eyee60dc2a1-f33c-4a05-9b50-8e3e8e59762924c86944-f75e-4854-953e-0980a866444b Presbyopia (age-related loss of focus)e60dc2a1-f33c-4a05-9b50-8e3e8e597629402f662a-cf97-4137-85dc-ca3ab2ed5cda Nonrefractive Errors Dry eye syndromee60dc2a1-f33c-4a05-9b50-8e3e8e597629402f662a-cf97-4137-85dc-ca3ab2ed5cda Cataracts Glaucoma e60dc2a1-f33c-4a05-9b50-8e3e8e59762924c86944-f75e-4854-953e-0980a866444b Macular degeneration e60dc2a1-f33c-4a05-9b50-8e3e8e597629402f662a-cf97-4137-85dc-ca3ab2ed5cda Optic neuritis (inflammation and irritation of the optic nerve)e60dc2a1-f33c-4a05-9b50-8e3e8e597629bf355803-2ef2-4c58-88b3-d170ad579135 Eye infection or injurye60dc2a1-f33c-4a05-9b50-8e3e8e597629402f662a-cf97-4137-85dc-ca3ab2ed5cda Retinoblastoma, or cancer of the retinae60dc2a1-f33c-4a05-9b50-8e3e8e59762924c86944-f75e-4854-953e-0980a866444b Crossed eyes (strabismus) Other Causes Diabetes Hypertension HIV/AIDS Sickle cell anemia Lupus Medication reaction Vitamin A deficiency Stroke Migraine Concussion Bleeding inside the eye (hyphema) Postural orthostatic tachycardia syndrome , a condition related to blood flowe60dc2a1-f33c-4a05-9b50-8e3e8e59762973ad5b66-b2d4-4102-99d8-0156607155d5 Eyestraine60dc2a1-f33c-4a05-9b50-8e3e8e5976296bdbb4af-3b0c-4bac-86f8-f31051e7896f The American Academy of Ophthalmology website features an extensive list of conditions that may be associated with blurry vision.

Prevention of Blurry Vision Prevention Take care of your health by eating well and get lots of rest.e60dc2a1-f33c-4a05-9b50-8e3e8e597629f464a514-cdb4-4394-920e-d8e7a418ebd7 Foods like dark leafy greens, fish, and other foods rich in omega-3 fatty acids, as well as vitamin A–rich foods like carrots and sweet potatoes, can also help you maintain eye health.e60dc2a1-f33c-4a05-9b50-8e3e8e597629855b4f9f-7629-4c64-af0c-7d0ad3d010db Wear sunglasses when you’re outside, and get eye exams regularly.e60dc2a1-f33c-4a05-9b50-8e3e8e597629f464a514-cdb4-4394-920e-d8e7a418ebd7 If you wear contacts, be sure to always wash your hands before putting them in or taking them out to minimize the risk of infections. If your blurry vision is caused by an underlying health condition, you may be able to resolve it by following your doctor’s recommendations for managing your symptoms. To prevent blurriness from eyestrain that results from looking at a screen too long, try following the 20-20-20 rule: at least every 20 minutes, look at something 20 feet away for at least 20 seconds. For blurry vision caused by eye dryness, try blinking a few times, using a warm compress, or using eye drops to lubricate your eyes.e60dc2a1-f33c-4a05-9b50-8e3e8e597629855b4f9f-7629-4c64-af0c-7d0ad3d010db
The Takeaway Blurry vision can have a variety of underlying causes. You should seek immediate medical attention if you experience sudden blurry vision. Treatment for blurry vision can include corrective eyewear, medication, or surgery. There are a number of ways to prevent blurry vision, such as eating correctly and limiting the amount of time you look at screens.
