Fig. 26. Straddling. The straddling meridians are 45 degrees off the glass axis, at roughly 35 and 125 degrees. As you move back from the eye while comparing meridians, the reflex at 125 degrees remains narrow (A) at the same distance that the reflex at 35 degrees has become wide (B). This dissimilarity indicates axis error; the narrow reflex (A) is the guide toward which we must turn the glass axis. (Corboy JM: Refining the cylinder. In Corboy JM [ed]: Retinoscopy, p 91. 4th ed.
