Webmore. If you have myopia or nearsightedness, you would use diverging lenses (concave) to shift the focus of your eye lens backwards so that it can focus on the retina. Just the opposite goes for hypermetropia or farsightedness, in which you would use converging (convex) lens to bring the focus closer. Web(b) f is strictly convex i for any a;b2C and any 2(0;1), the above inequality is strict. The following equivalence is immediate from the de nitions. Theorem 1. Let C RN be non-empty and convex and let f: C!R. fis convex i fis concave. fis strictly convex i fis strictly concave. f is both concave and convex i for any a;b2RN and any 2(0;1), f( a+ french\\u0027s string bean casserole recipe
