Astigmatism is a common refractive error in which light is not focused properly on the retina, resulting in vision problems. It affects about one in three people in the U.S. and can affect both children and adults. If you have this condition, both near and far objects may appear blurred or distorted.
The eyes are sensitive organs. Indeed, a single speck of dust or eyelash can be bothersome. While these small objects often go away quickly, some can cause injuries. An ejected metal shard or piece of glass that hits and penetrates the eye would require immediate medical attention.
