The Objective of the present research was to study the improvement of near vision with ready-made spectacles for presbyope in Chachoengsao province. Retrospective cross-sectional analytic study was conducted in 309 volunteers at Sanamchaiket district whose ages were 35 years and above. Visual acuity was measured in presbyopic patients, and then ready-made spectacles were given as a trial. Visual acuity of near distance was measured at the time before and after correction with ready-made spectacles. Aim was to achieve the visual acuity of 20/50 or better. The number of volunteers was 129. Out of these, 96.12 percent (124 of 129) achieved the aim of the visual acuity (124 of 129). In conclusion, ready-made spectacles were effective in correcting near vision for presbyope at any group of ages and both sexes in Chachoeungsao province. If the difference of refractive error between both eyes was greater than +1.25 Diopter ready-made spectacles were ineffective.
