Windshield scratches

Hi, I have a few scratches on my windshield; anyone know if they have shops that buff them out? The scratches are not deep at all, but I've got like three short ones which are visible to the eye when driving.

My question is, where do I go to get it smoothed out? Thanks.

are they scratchez??? or cracks?? if they are cracks, im pretty sure there is nothing u can do about the visual part of it...tho i could be wrong...
