Investigation of the unfused cross cylinder test as an alternative method for the determination of spherical distance refraction end points
Background: The duochrome test is commonly used to refine the final sphere in refraction at different stages of a subjective refraction. The unfused cross cylinder test is mainly used to determine the near reading addition with a combination of astigmatic lenses. Aim: To investigate if the unfused...
