Comparison of the Hodgen's near point red-green test to the near point binocular cross cylinder test

Abstract

The purpose of our project is to find the repeatibility of both Hodgen's red-green test at near and the fused crossed cylinder test. By correlating the Hodgen's test with the already accepted cross cylinder, we will be able to determine if they are tests of the same function and whether or not they may be substituted for each other.
