What to Focus On

  • Eye diameter is approximately 2.3 cm
  • Cornea provides most of the refraction
  • Iris controls pupil size and light entry

  • Accommodation: ability to adjust focal length
  • Relaxed muscles = thin lens = distant vision
  • Contracted muscles = thick lens = near vision

  • Myopia: can see near, cannot see far clearly
  • Myopia corrected by concave lens
  • Hypermetropia: can see far, cannot see near clearly

Common Mistakes to Avoid

Myopia (nearsightedness) should be corrected with a convex lens because myopic people need help seeing distant objects

The eye lens becomes thicker to see distant objects and thinner to see near objects

White light contains only the seven colors of VIBGYOR, and there are exactly seven distinct colors in a spectrum
