Abstract
Presbyopia is part of the aging process where the eye losses the ability to focus at different depths. Progressive additive lenses (PALs) are routinely prescribed to facilitate the accommodation system for those with presbyopia. However, it is unknown why some individuals are more likely to adapt to PALs compared to others. Eighteen subjects who had all tried PALs participated in a vergence motor learning experiment. Peak velocity was measured. A generalized morphological component analysis (GMCA) was applied to ensemble vergence response data to dissect responses into their preprogrammed transient and feedback controlled sustained component. Results show that subjects with a greater peak velocity were more likely to adapt to progressive lenses. The transient component from GMCA was highly correlated to peak velocity suggesting that the larger the magnitude of the transient component the more likely a presbyope was to adapt to PALs. ©2010 IEEE.
