Blurry vision in one eye or both eyes

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.
