lens

The abscence of light

wavelengths of visible light
able to see things that are closer more clearly than things that are farther away
Nearsighted
is made up of millions of light-sensitive cells
retina
Reflects light inward
convex lens
If the curvature of the cornea isn’t perfectly spherical, light is dispersed causing;
