Abstract: Aim: This study aims at finding an effective optical low vision device for near, which will enhance the reading speed in patients with dry ARMD. Objectives: To suggest the most suitable optical low vision device for near at reading. Methods: 43 patients with dry ARMD were taken with detailed history taken. BCVA done for distance with Log MAR and for near with Bailey Lovie chart. Calculation for magnification done for near. After LVDs trial done for near the MN read chart was given to the patient to read the chart with each given devices (Stand, Hand- held, Bar, Dome and Spectacle magnifiers) for reading and the time taken to read the chart was noted. The reading speed was calculated as a words per minute (WPM). Reading acuity and critical print size were also calculated with each device.Results: The mean magnification for all the five magnifiers (Stand, Hand-held, Bar, Dome and Spectacle magnifiers) was 3.2±0.79. The maximum reading speed in wpm was found with Hand-Held magnifier (127.33 ± 43.25) whereas minimum reading speed was with bar magnifier (89.07 ± 51.46). All these patient (N=43) had a best corrected visual acuity between 0.48 to 1 log MAR in the better seeing eye. Conclusion: All magnifiers shows the better and functional reading speed in all the Dry ARMD patients taken. Although the average reading speed was high with hand- held magnifier. So, we can conclude that every magnifiers are equally better in case of reading speed and any of them can be suggested to these patients depending upon their comfortability.
