Astigmatism is a refractive eye disorder caused by a misshapen cornea at the front of the eye. A normal cornea is spherical in shape, but some people are born with a more oblong shaped cornea that projects two points of light on to the retina at the back of the eye. The resultant image processed by the brain is blurred, the degree of blur determined by the distance between the two points on the retina. The closer the points are the less blurred the image appears.
Pinhole glasses reduce the blur of astigmatism by limiting the distance between the two points of light on the retina, thus helping sufferers to see more clearly.If you're looking to strengthen your eyes effortlessly and naturally, this very well may be the most valuable video you ever watched on the topic. -- Click Here To Watch The Free Special Video Report --
