Why low-index lens cann't fit me?

My optometrist told me that I need 1.61 lenses for my prescription eyeglasses because the SPH of my eyes is too high, 800 power. So what's the problem if I want to use 1.49 or 1.56 lenses?

It`s the problem of refractive index of lenses ,if you wear lenses which are not matched to your SPH, it`s very harmful to your eyes,your eye problem will become much more serious.
