It is shown that the apparently flattened celestial vault can be represented by a geocentric sphere at a height of 3000-4000 km above the surface of the earth. It is also argued that our eye estimates the distance to this 'sky sphere' by its apparent opacity which is a function of the air mass. A hypothesis regarding the physiology of distance vision is proposed.
