Purpose To assess the effects of multifocal soft contact lenses ( MF SCL s) used for myopia control on visual acuity ( VA ) and subjective quality of vision. Methods Twenty‐four young adult myopes had baseline high and low‐contrast VA s and refractions measured and quality of vision assessed by the Quality of Vision (QoV) questionnaire with single vision SCL s. Additional VA and QoV questionnaire data were collected immediately after subjects were fitted with Proclear MF SCL s and again after a 2‐week adaptation period of daily lens wear. Data were collected for two MF SCL designs, incorporating +1.50 and +3.00 D peripheral near additions, with a week washout period allowed between the two lens trials. Results High‐ and low‐contrast VA s were initially reduced with both MF SCL designs, but subsequently improved to be not significantly reduced in the case of high‐contrast VA by the end of the 2‐week adaptation period. The quality of vision was also reduced, more so with the +3.00 D MF SCL . Quality of Vision (QoV) scores describing frequency, severity and bothersome nature of visual symptoms indicated symptoms worsening rather than resolving over the 2‐week period, particularly so with the +3.00 D MF SCL . Conclusion Low and high add MF SCL s adversely affected vision on initial insertion, with sustained effects on low‐contrast VA and QoV scores but not high‐contrast VA . Thus, high‐contrast VA is not a suitable surrogate for quality of vision. In prescribing MF SCL s for myopia control, clinicians should educate patients about these effects on vision.
