Retrospective cross-sectional analytic study was conducted in 309 volunteers atSanamchaiket district whose ages were 35 years and above. Visual acuity was measured in presbyopic patients, and thenready-made spectacles were given as a trial. Visual acuity of near distance was measured at the time before and aftercorrection with ready-made spectacles. Aim was to achieve the visual acuity of 20/50 or better. The number of volunteers was129. Out of these, 96.12 percent(124 of 129) achieved the aim of the visual acuity (124 of 129).
