ABSTRACT:
Disclosed is a lens for treating the diplopia and amblyopia and glasses using the same including a concave and convex part wherein a concave part and a convex part are continuously and repeatedly formed on the overall surface of a lens body facing an eye ball of a person who wears the lens. Here, the concave pan has a radius of curvature of R and the convex part has a radius of curvature of r. The relation between R and r is R>>r. There is no esthetic defects ostensibly since an eye through the glasses using the lens look like a normal eye seen from the outside of the glasses and covers a normal eye on behalf of the conventional eye patch by hardly seeing an object of the outside seen from the inside of the glasses, thereby improving the eyesight of the patient suffering from the diplopia or the amblyopia.
