Retinal disparity<span> is defined as the way that your left eye and your right eye view slightly different images. </span>
Convergence refers to the eyes' disposition to rotate inward toward each other in a coordinated manner in order to focus effectively on nearby objects. <span>

It can affect the environment because it could absorb into the ground and contaminate the groundwater, then this could runoff into a pond, river, lake, etc., which would then contaminate that water source. This also negatively impacts wildlife because they rely on these water sources to drink water, bathe, and/or catch food (ex: a bear catching a fish in a river).
