In Keplerian, the focal lengths of object and eye are inside the telescope while in Galilean the two focal lengths are outside the telescope. In Keplerian, the focal lengths of object and eye are outside the telescope while in Galilean the two focal lengths are inside the telescope. Keplerian telescopes are better for hyperopic patients whereas Galilean telescope is better for myopic patients. The image of Keplerian telescope is erect whereas the image of Galilean telescope is inverted.

It has a uniform size progression of 0.1 log units per line It is portable and can be used to measure visual acuity at different distances It has options of using Landolt C and other modes Improvement in VA of 2 lines or more have been found in a number of patients All of the above are advantages of using LogMAR charts

It is criticized since patients perform better with a distance visual acuity chart than a near acuity chart The Feq equals the best corrected near acuity divided by the viewing distance In order to achieve fluent reading, the Feq should be half of the Kestenbaum’s rule value. It is criticized because we use a threshold visual acuity.
