The image of an object formed on the retina of human eye is:

AVirtual and inverted

BVirtual and erect

CReal and inverted

DReal and erect

Answer:

C. Real and inverted

Read Explanation:

  • At rest, the lens in the normal eye focuses images of distant objects on the retina.
  • It acts in much the same way as a biconvex optical glass lens, however, it cannot be moved forward.
  • Thus, the refractive power of the lens is a function of the curvature of the lens surfaces, as well as the refractive index of the cell mass.
  • The closely packed, highly ordered array of lens cells is essential for optical quality, and even small defects in lens fiber cell anatomy can cause detectable spherical aberration.
