Subjective Refraction
Patient:Kim, DavidAge:30Case:calm-myopeSeed:23891
SPHERE-1.75CYL / AXIS-0.50 x 180
Which side is clearer? Red or green?
"I think option 2 is a little clearer." (reliability: 87%)

Retinoscopy Result (Objective Anchor)

-1.75 / -0.50 x 180
This objective measurement stays visible throughout refinement. The reflex is optics responding to a lens; this is the anchor the subjective endpoint should not abandon.

Measurement Model

Same eye + same lens = same threshold, always.
Patient reliability: 87%
Responses sample around threshold.
