The myopia
The myopia is the most widespread visual defect. The myope has difficulties to see from far, with a blurred perception of distant objects. On the other hand their near vision is very good.
> The correction of the myopia :
Concave lenses correct the myopia, they are thicker at the edge than at the centre. The lens thickness raises with the correction value. It can be limited by choosing thinned lenses.
