García‐Marqués JV, Macedo‐De‐Araújo RJ, Cerviño A, et al. - Researchers conducted this randomized, double‐masked crossover study for comparing the optical and visual performance of a dual‐focus (DF) contact lens used for myopia control with a single‐vision (SV) contact lens of the same material. Participants in the study were 28 healthy, myopic volunteers between 18 and 32 years of age (23.49 ± 4.07 years). Refraction, best‐corrected visual acuity (VA) and aberrations for 3 mm and 5 mm pupil diameters have been quantified without a contact lens in situ. Findings revealed that there were no statistically significant differences between baseline, DF, and SV conditions in best‐corrected VA and stereopsis. The design of the DF contact lens reduced the psychophysical and psychometric visual quality scores in the short term under dim-light conditions when compared with the design of a single-vision contact lens of the same material. The lens design was uninfluenced by VA and stereopsis.
