When only one eye is blurry, it can be a result of several different issues, which can be either simple causes and other more serious medical issues.
Common non urgent causes of one eye being blurry include refractive errors, eye strain, dry eye syndrome, cataracts and even eye infections and allergies.
Conditions like pink eye also known as conjunctivitis or blepharitis can cause discharge, inflammation and eye blurriness.
Cataracts, which is clouding of your eye's natural lens, that develops slowly and causes dim, hazy or foggy and blurry vision.
Eye strain that can result from prolonged use of computer screens and other digital screens or even poor lighting can also cause temporary blurriness that can occur in one eye or both eyes.
Dry eye syndrome, which is a lack of moisture or poor tear quality can also make the surface of one of your eyes uneven, which can cause fluctuating blurry vision or even irritation or a gritty feeling.
It's also common to have different prescriptions for each eye.
And having an outdated prescription such as for eyeglasses or contact lenses for astigmatism, farsightedness or nearsightedness can cause one of your eyes to focus poorly and lead to blurry vision.
Other more serious and urgent causes of blurry vision in one eye include, glaucoma or optic neuritis, corneal abrasion, retinal detachment and strokes or mini ke TIA.
Conditions that involve sudden increased pressure in your eye or inflammation of your optic nerve can also cause rapid changes in your vision and require immediate medical treatment.
Corneal abrasion, which can also cause one eye to be blurry is a scratch on the surface of your eye, which is often from debris or even from contact lenses, which can and will cause sharp pain and blurry vision.
Retinal detachment, which can also cause blurry vision in one eye, is a medical emergency, in which your retina pulls away from the back of your eye.
Symptoms of retinal detachment are a sudden shadow in your field of vision, flashes of light or a sudden burst of floaters.
And a sudden loss of vision or blurry vision in one eye can also be a sign of a stroke, which is often accompanied by numbness, weakness on one side of the body and difficulty speaking or a severe headache.
If the blurry vision in one eye goes away within a few hours or the next day, then it's likely nothing serious.
But if the blurry vision lasts longer than a day or gets worse or you have any signs of stroke, pain or believe you may have a retinal detachment you should go to the ER.
