Correcting Vision

Short Sight is corrected with Diverging lenses

  • Short sighted people cant focus on distant objects
  • This is due to the eye ball is too long, or the lens is too powerful
  • So the uncorrect image is formed in front of the retina
  • To correct it a diverging lens (with a negative power) is put in front of the eyes - diverges light before it enters the eyes - the eye lens can focus it on the retina

Long Sight is corrected
