When bandaging one of a victim's eyes, why should both eyes be covered?

Covering both eyes when bandaging one eye is important because the eyes work in coordination with one another. If only one eye is covered and the other remains uncovered, the uncovered eye will continue to move normally, which can create discomfort and confusion for the victim. This is due to the phenomenon known as consensual reflex, where movement in one eye can trigger movement in the other. By covering both eyes, it minimizes visual conflict and provides a more stable environment for the injured eye to heal. This approach helps to prevent further strain or discomfort that the victim may experience if they are able to see with the unaffected eye while the other is injured.
