The Accommodation Response and Facility between Children and Young Adults
Tonic accommodation decreased with age among children. In young adults, late-onset myopia will develop due to occupational near vision demands. This study aims to investigate the accommodation response and facility between children and young adults, in emmetrope (non-myopic) and myope group. The accommodation response and facility of young adults and children were measured using monocular estimation method (MEM), monocular accommodative facility (MAF) and binocular accommodative facility (BAF) with an exposure of near task for 15 minutes. Near task has significantly increased the lag of accommodation in all groups (p<0.05). However, the accommodation facility was not affected by near work in all groups (p>0.05).
Keywords: accommodation response, accommodation facility, myopes, emmetropes.
