In subjective refraction the examiner places spherical lenses in the trial frame and changes them step by step until the patient reports the clearest vision, then adds cylindrical lenses to refine the correction for astigmatism. Lens powers in trial sets are read in dioptres, and the 0.25 steps at the low end of this set allow fine adjustments. The prisms are used when checking how the two eyes work together.
The accessories widen the range of tests: the Maddox rod and the red and green glasses for binocular balance checks, the stenopaic slit for locating the axis of astigmatism, and the pinhole for judging whether reduced vision is optical in origin. Optometry colleges use the Optical Lens Set to train students in these routines. Hold lenses by the rim and return each one to its own slot so the set stays complete.
