<prompt> On performing refraction using plane mirror on a patient whos has a refractive error of -3 D sphere with -2 D cylinder at 90 degree from a distance 1 metre under no cyclopgia, the reflex would be seen to moveWith the movement in the horizontal axis and against the movement in the veical axisWith the movement in both the axisAgainst the movement in both the axisWith the movement in the veical axis and against the movement in horizontal axis  <response>: Error of -3 D sphere that is person using concave spherediverging advised in cases of myopia. Reflection of ligth with Retinoscope 1. Against opposite movement : Myopia -1 2. With same movement Myopia -1 or Emmetropia 1 or Hypermetropia value 3. No movement Myopia -1 This patient is having a -3DS with -2DC x 90 - compound myopic astigmatism, so the reflex would move in opposite direction to the beam irrespective of the axis
