Rigorous logical reasoning requires some axioms, and someone who has just gained his or her sight has no reasonable axioms to apply (or, rather, no way to decide, even on the basis of experience, which axioms are reasonable to impose). Suppose that I felt an object and discovered that it felt the same from all angles. Could I conclude that it tasted or smelled the same from all angles? I don't think that is a reasonable conclusion. Why then should I conclude, with no prior evidence to guide me, that it would look the same from all angles?
