Answer 2

Answer:

Myopia and hypermetropia are both easily corrected at Optical Masters using prescription glasses or contact lenses specifically designed to counteract the effect.

For myopia, a concave lens (minus powered) is placed in front of a myopic eye, moving the image back to the retina and clarifying the image.
