Answer 1

Answer:

A person with myopia or short sight can see objects close to them clearly, but not far away. ... Myopia is corrected by spectacles or contact lenses with lenses which are 'minus' or concave in shape. So if you're short sighted, your prescription will have a minus lens power, e.g. -2.50D.
