Sudden blurred vision is a fairly common condition that can result from any problem with the eye, such as the cornea, optic nerve, or retina. Blurry vision can progress slowly due to long-term medical conditions and should be treated early to avoid serious complications to vision.

1. Common causes of sudden blurred vision

Some of the main causes of sudden blurred vision, which should be treated as soon as possible to help prevent eye damage and permanent vision loss include:
1.1 Retinal detachment Retinal detachment occurs when Retinal tissue detaches far from the back of the eye and loses its blood supply and nerves.
With retinal detachment, you will see flashing lights or dark spots in front of your eyes, then an area of ​​blurred or no vision in the eye. Without urgent treatment, vision in the affected area can be permanently lost.
1.2 Stroke Blurry or loss of vision in both eyes can happen when you have a stroke, affecting the part of the brain that controls vision. An eye-related stroke can cause blurred vision or loss of vision in only one eye. You may also experience other symptoms of a stroke, such as loss of speech or weakness on one side of your body.
1.3 Transient ischemic attack (TIA) A transient ischemic attack (TIA) is a stroke lasting less than 24 hours. The main causes of TIA often include hypertension, alcoholism, smoking, obesity, insulin resistance, dyslipidemia, diabetes, drug use, or physical inactivity. A transient ischemic attack can cause typical symptoms such as blurred vision in one or both eyes.

1.4 Macular degeneration (wet form) The macula of the eye is the central region of the retina. When you have macular degeneration (wet form), abnormal blood vessels develop, allowing blood and other fluids to leak into the macula.
Macular degeneration (wet) can cause blurring and loss of vision in the central part of the visual field. Unlike dry macular degeneration, this type can come on suddenly and progress very quickly.
1.5 Angle-closure glaucoma Angle-closure glaucoma occurs when the drainage system in the eye becomes blocked. In this situation, the pressure inside the eye can build up very quickly, causing the eye to become red and painful.
Angle-closure glaucoma is a medical emergency that should be treated with eye drops or taken orally to reduce pressure inside the eye. In some specific cases, the patient may require laser procedure to open the peripheral iris or trabeculectomy - corneal surgery
1.6 Damage to the cornea The cornea is a coating directly in front of the eye. When the cornea is scratched or injured, it can lead to corneal abrasion. Besides blurred vision, you may also feel like something is inside your eye.
1.7 High blood sugar Too much blood sugar can cause sudden blurred vision.

1.8. Anterior chamber hemorrhage Anterior chamber hemorrhage is a condition in which blood collects inside the front of the eyeball. The main cause of this problem is bleeding that occurs after an eye injury. In addition, when bleeding will cause pressure inside your eye to rise, which can make your eyes feel very painful.
1.9. Iritis The iris is the colored part of the eye. Iritis occurs when your body has an autoimmune reaction or an infection that causes the iris to become inflamed.
Iritis can occur on its own or as part of an autoimmune condition, such as sarcoidosis or rheumatoid arthritis. In addition, it can also occur due to an infection, such as herpes.
When you have iritis, you will have pain in your eyes and sensitivity to light, also known as photophobia.
1.10. Keratitis Keratitis is an eye condition caused by an infection. In addition, using contact lenses for too long or improperly cleaning them can also be factors that increase the risk of this disease.
1.11 Macular Hole The macula (macular) is the center of your retina, responsible for your central vision. When the macula is torn or ruptured, it can lead to blurred vision. Usually, the macular hole affects mainly one eye.
1.12 Optic Neuritis The optic nerve connects your eyes to your brain. Optic neuritis occurs as a result of an autoimmune reaction or multiple sclerosis. Other causes include lupus or infection. Usually, optic neuritis affects only one eye.

1.13 Temporal Arteritis Temporal arteritis is an inflammation of the arteries of medium size. Inflamed blood vessels around the temples can cause a throbbing headache in the forehead, making your vision blurred or disappear.
