i think you're mixing up eyesight with heat pits there trouser.
The heat -pits are lined with a layer of cells that contain many thermo-receptors , each of which is linked to the brain. Using these cells , snakes can detect minute rises in temperatures , such as
those radiated by the small warm blooded creatures that are their prey.
the pits allow snakes to detect changes in temperature of 0.002 degrees C.
Eyesight / vision is another thing again.
