Dear student 
Yes, technically a shadow shows reflection.Because, a shadow is not a physical object, it is just the region where light do not strikes the screen. Shadow is not a dark ray, it is just the result of objects blocking light.
The Reason is “Divergence of Light”
Myopia is when the light coming from different objects in your vicinity gets converged by the eye lens in front of the retina rather than on it. So prescription glasses make use of divergent (concave) lenses to correct for this defect.
