A final year optometry student asked me '' What is a spherical eye'' when i responded ''An eye where the cornea is a perfect sphere or a sphere'' he asked me to explain in simple terms.. i dont know what else to say, also he asked what is the power or give examples of powers of spherical eyes.
I'm baffled by this because i know of spherical corrective lenses for myopia and hyperopia but nothing about spherical eye and the power.
Help please
