Near/Distant

• What muscles/ligaments are responsible when the eye is looking at near/distant things?

  • Cilliary mucles
  • Suspensory ligamnets
• How does the eye focus on distant objects?

  • Cilliary muscles contract
  • Suspensory ligaments relax
  • Lens is pulled tight becoming thin and less curved
  • Less light is refracted
• How does the eye focus on near objects?

  • Cilliary mucles relax
  • Suspensory ligaments contract
  • Lens is thicker and more curved so refracts more light
