loss of rihnt visual fields from both eyes
Hemianopia or hemianopia is a defect in the right or left half of the visual field. It can affect one eye but can also affects both eyes.
Normal vision in both eyes results in the right half of the visual field being dominant. The absence of vision in both eyes results in the left half of the visual field being dominant.
If there is normal vision in both eye for the right half visual field but there is absence of vision in both eyes for left half of the visual field, then the lesion is in the left eye. Since the vision for right eye is clear, the lesion is in the left.
each eye is not primarily connected to one hemisphere only instead, each visual half field is projected to the opposite hemisphere so, if an image is seen in the right visual field it would be seen in the left hemisphere and if an image is seen in the left visual field it would be seen in the right hemisphere
