Visual acuity is the spatial resolving capacity of the visual system. Dynamic Visual Acuity (DVA) defined as a very complex visual function that requires the observer to detect a moving target, to visually acquire it by eye movements, and to resolve critical details contained it, all in a relatively brief time exposure. Aim: To create a low cost productive, portable and user friendly Digital Dynamic Visual Acuity (DDVA) Device and measure DVA. Methodology: It is an experimental study in which there are two phases. First phase consist of creating the device and in second phase measuring the DVA in normal subjects using this device. The study was conducted between the time period of September 2017 to March 2018.First, the device was created using HTML, CSS and JAVASCRIPT language and the chart was designed and calibrated for 1 meter distance. 31 subject had undergone brief history was taken and undergone visual acuity, objective and subjective refraction. Then the Dynamic Visual Acuity was measured using this device. Result: Total 31 subjects (age group between 17 to 28) had undergone Vision assessment and Dynamic Visual Acuity measurement using DDVA Device. There is a significant difference exists for mean static and dynamic values of decimal visual acuity (P__ampersandsignlt;0.0001) in the studied sample. When the stratified analysis by gender was performed the similar trend was noticed (P,0.0001 for both the gender). Conclusion: When compared to Static visual acuity a significant drop of Dynamic visual acuity was noticed measured using DDVA device. The device was calibrated for 45 RPM.
