A1.21
Lens Accommodation and Vergence
Cards in this group · 4
- A1.21.1The lens focuses on objects at different distances by changing its curvature
- A1.21.2Accommodative amplitude declines with age, the physiological basis of presbyopia
- A1.21.3Focusing, pupil constriction, and binocular convergence occur together in natural near viewing
- A1.21.4Displays that pair a fixed focal depth with variable vergence break this coupling
