Table 3: Subjective preferences of the prismatic and the
non-prismatic correction in both groups. The bold marked preferences vary
(between examination and 2nd check-up) at statistically significant
level p < 0.05
(column „Wilcoxon test results). *There were 2 volunteers unable to
participate on trial wearing of prismatic spectacles for near vision in the
main group and one of them wasn’t able to undergo the binocular refraction
examination at near at all.
