Eye health is one of the most undervalued but important aspects of our overall health. Your eyes are an important part of your health. There are many things you can do to keep them healthy and make sure you are seeing your best. Millions of Americans suffer from eye disorders and one of the more common issues is called Astigmatism. This common eye problem will cause blurry vision. How does this happen? What is called the "lens" or the cornea —the clear layer that covers your eye— possesses slight imperfections which leads to the eye being unable to refract light correctly.
