Step 1: Using the +/-0.50DS on the confirmation set to determine the initial best sphere correction.

Step 2: Presenting the 0.50JCC initially @ 90deg to determine any presence of astigmatism on that axis.

Subjective Refraction is an attempt to determine, by trial and error using the patient’s cooperation, the combination of lenses that will provide the best corrected visual acuity (BCVA). It is a clinical examination used by orthoptists, optometrists and ophthalmologists to determine a patient's need for refractive correction, in the form of glasses or contact lenses. The aim is to improve current unaided vision or vision with current glasses.
