Circle Lens vs. Normal Lens
You may have heard about the growing popularity of the circle lens , but might not be sure of what makes it so special. In that case you need to know that a circle lens is different from a normal contact lens. Normal lenses cover the cornea of your eyes. The cornea is the center of the eye, which reflects your eye color and aid vision. Circle lenses are larger and cover not only the cornea but the sclera as well. The sclera is the white portion of the exposed surface of your eyes. So it actually covers the entire iris of the eye.
