Myopes have reduced accommodative facility, especially at distance, due to slower accommodation and disaccommodation velocities compared to emmetropes. Near accommodative facility differences were less pronounced.

Area of Science:

  • Ophthalmology
  • Optometry
  • Vision Science

Background:

  • Accommodation is crucial for clear vision at different distances.
  • Myopia (nearsightedness) affects distance vision clarity.
  • Understanding accommodative dynamics is key to visual function assessment.

Purpose of the Study:

  • To investigate dynamic refractive changes during accommodative facility testing.
  • To compare accommodative facility between myopes and emmetropes.

Main Methods:

  • Ten myopes and ten emmetropes participated.
  • Refractive error in myopes was corrected with soft contact lenses.
  • Monocular accommodative facility was measured using automated flippers and a photorefractor for objective dynamic accommodation response.

Main Results:

  • Myopes showed significantly lower distance accommodative facility rates than emmetropes.
  • Accommodation velocity was lower in myopes for distance facility.
  • Disaccommodation velocity was lower in myopes at both distance and near.

Conclusions:

  • Myopes exhibit reduced distance accommodative facility due to slower accommodation and disaccommodation velocities.
  • Near accommodative facility differences were less significant, despite slower disaccommodation in myopes.
  • These findings highlight distinct dynamic accommodative responses between myopes and emmetropes.
