Video is about the very basic test in the field of optometry which gives us the knowledge about vision and visual acuity.
This video will elobrate on how to perform the test,analyze and record it.
Snellen chart: Each individual letter subtends an angle of 5 minutes and each component of letters subtends an angle of 1 minute at the nodal point of eye from the distance in meters written as numerical.
The LogMAR Chart is designed to enable more accurate estimates of acuity as compared to other acuity charts eg: the snellen chart.
Each line of the LogMAR chart comprises the same number of test letter,when using the LogMAR chart,visual acuity scored with reference to the logarithm of the Minimum Angle of Resolution,as the name suggests.
Do practice the test on routine to get expertise in recording the visual acuity.
Thank You.
