What is blurry vision?
Blurry vision is the loss of sharpness of eyesight, making objects appear out of focus and hazy. The primary causes of blurred vision are refractive errors — nearsightedness, farsightedness and astigmatism — or presbyopia. Blurry vision can also be a symptom of more serious problems.
These problems may include a potentially sight-threatening eye disease or neurological disorder. Blurred vision can affect both eyes, but some people experience blurry vision in one eye only.
Cloudy vision obscures objects and causes vision to appear “milky.” It is similar to blurry vision and is sometimes indistinguishable. Cloudy vision is usually a symptom of specific conditions such as cataracts.
Blurry vision: Causes and treatment
There are several refractive errors and other minor issues that can cause blurry vision.
To determine why you have blurry vision and what is causing it, see an eye doctor for a comprehensive eye exam. Some of the more common causes of blurry vision include the following:
Myopia
Symptoms of myopia (nearsightedness) include squinting, eye strain, headaches and blurry vision in one or both eyes. Myopia is the most common refractive error and causes objects in the distance to appear blurred.
Eyeglasses and contact lenses are the most common ways to correct nearsightedness. Corneal reshaping and refractive surgery such as LASIK and PRK are also common means of correction.
