Pregunta 109

Which eye structures bend incoming light to help form a focused image on the retina, the light-sensitive inner surface? Select all that apply.

  1. CorneaRespuesta correcta
  2. Optic nerve
  3. LensRespuesta correcta
  4. Retina alone

Explicación

The curved cornea begins bending incoming light, and the lens adjusts the focusing needed to direct that light onto the retina. The retina is the receiving surface rather than the structure doing all the bending, and a nerve cannot focus light mechanically.
