Final answer:
The patient's inability to see objects on the left with both eyes is known as left homonymous hemianopia, which is due to damage to the right visual pathways in the brain.
Step-by-step explanation:
The visual field defect described, where the patient does not see objects on the left with both eyes, is known as left homonymous hemianopia.
This condition occurs when there is damage to the right visual pathways in the brain, which can be caused by various conditions, such as stroke, brain injury, or tumor. The information from the left visual field is processed by the right side of the brain; therefore, any disruption on that pathway results in a loss of vision on the left side for both eyes.
