Analysis of Decentration Tolerance^* for 3- and 6-mm Pupil Diameters

	r̄ (μm)
Simulation	3-mm PD	6-mm PD
(1) Uncorrected with optimum refraction for 3-mm PD at centered position	766±211	624±378
(2) Uncorrected with optimumn refraction for 3-mm PD	1219±210	633±308
(3) Best-corrected	1279±175	797±461

PD = pupil diameter

Maximum permissible decentration to maintain a decrease of VSOTF<0.2 log units.

Note. The radius r̄ is the mean length of the vectors between the center and the locations with threshold values.
