Lens Accommodation and Vergence

Cards in this group · 4

  1. A1.21.1The lens focuses on objects at different distances by changing its curvature
  2. A1.21.2Accommodative amplitude declines with age, the physiological basis of presbyopia
  3. A1.21.3Focusing, pupil constriction, and binocular convergence occur together in natural near viewing
  4. A1.21.4Displays that pair a fixed focal depth with variable vergence break this coupling
