What to Focus On

  • The eye is approximately spherical with a diameter of about 2.3 cm.
  • Cornea is the front transparent bulge through which light enters the eye.
  • Most refraction in the eye occurs at the outer surface of the cornea.
  • Myopia means near-sightedness.
  • In myopia, distant objects appear blurred and the image forms in front of the retina.
  • Myopia may be caused by excessive curvature of the eye lens or elongation of the eyeball.
  • The angle between the two lateral faces of a prism is the angle of the prism.
  • At the first surface, light bends towards the normal.
  • At the second surface, light bends away from the normal.

Common Mistakes to Avoid

The cornea only lets light enter the eye; most refraction happens in the eye lens.

The pupil controls the amount of light entering the eye by itself.

The retina is the lens at the back of the eye that bends light to form the image.
