Answer
It would cause blindness in the left half of the visual field; it would not affect the visual reflexes.
Work Step by Step
Fibers from the left eye hemidecussate at the optic chiasm, that is, some fibers cross to the contralateral side (opposite side) and some remain on the ipsilateral (same) side. The lateral half of the neurons ( the ipsilateral ones) contribute to the optic radiation. The rest of the optic radiation consists of neurons from contralateral side( medial aspect of visual field. Therefore, damage to the optic radiation on one side of the brain would impair vision of the lateral aspect of the field of the ipsilateral side.
Visual reflexes are controlled by the the superior colliculus ( extrinsic eye muscles) and the pretectal nuclei, which control pupillary and accomodation reflexes.
