Blurred Vision: Blurred vision is also known as blurry vision is the loss of sharpness of eyesight, making objects appear outside of the focus and hazy. The causes of blurred vision are nearsightedness, farsightedness, and astigmatism or presbyopia. That’s all causes are refractive errors. But blurry vision can also be a symptom of more serious problems, such as sight-threatening eye disease or neurological disorder. Blurred vision can touch both eyes, but some people encounter blurry vision in one eye only.
Cloudy vision, where objects are shaded and appear “milky,” is frequently mistaken for blurry vision. Cloudy vision normally is a symptom of cataracts, but blurry and cloudy vision can both be signs of a serious eye problem.
The blurry vision raises your risk for an eye disease called diabetic retinopathy. High blood sugar can damage the tiny blood vessels in your retina, that senses light. That can begin to swelling in a part of the retina known as the macula, new and unwanted blood vessels developing in the eye, and bleeding inside the eye.
A qualified eye specialist can estimate the extent of your blurred vision and decide the case with a comprehensive eye exam. The eye exam comprises spatial contrast sensitivity, slit-lamp, and standard Snellen eye chart tests.
