Question

How has the eye accomplished correction for spherical aberrations? Fill in the blanks. The _____ is flatter at its ____ than at its ______, and the ______ is denser in the center and hence refracts more strongly at its core than at its outer layers.

Answer 1

Cornea, margin, center, lens

Step-by-step explanation:

Spherical aberration is defined as a class of aberration which is found in various optical systems which use the elements with various spherical surfaces.

The eye accomplished correction for spherical aberrations through cornea and lens.

The cornea is a transparent front part of eye. In humans, the cornea's refractive power is about 43 dioptres. The cornea is flatter in shape at it margin than at its center.

The lens in the eye focuses light rays which pass through it so that clear images of objects can be created which are positioned at different distances. Eye lens is of ellipsoid and biconvex shape. It is denser at the center.
