The correlation between contact lenses and myopia progression has also gradually attracted attention. It is estimated that 50% of the global population will be myopic by 2050 1. With technological advances and changes in lifestyle, the global myopia rate has rapidly increased annually. Contact lenses with different optical designs have a great influence on binocular vision and visual behavioral performance. Although the vergence function showed a significant change, it did not show worse trends when wearing contact lenses. Compared with single-vision contact lenses, progressive and bifocal contact lenses relaxed accommodation, reduced the lag of accommodation, and improved visual behavioral performance. In terms of visual quality, single-vision contact lenses (Lens 1) were the most comfortable, progressive and bifocal contact lenses reduced distant visual acuity and stability, progressive contact lenses (Lens 2) had more complaints about halos at night, and bifocal contact lens (Lens 3) users were more likely to have double vision. Furthermore, both progressive (Lens 2) and bifocal (Lens 3) contact lenses enhanced overall visual behavioral performance. Bifocal contact lenses (Lens 3) affected negative and positive relative accommodation, but vergence facilities and accommodative facilities also progressed. Progressive contact lenses (Lens 2) reduced the lag of accommodation and near vergence in addition, vergence facilities and accommodative facilities were also improved. Single-vision contact lenses (Lens 1) increased accommodative lag, negative relative accommodation, and distant and near vergence however, vergence facilities, accommodative facilities, heterophoria, and the comfort and posture balance dimensions in the VBP questionnaire were improved. In addition, subjects completed the VBP and visual quality questionnaire again at the end of the examination. Eye examinations were performed on the first day (CL baseline), 2nd week, and 4th week of wearing the lenses. All the subjects were randomly grouped to wear different optical designs of single-vision, progressive, and bifocal contact lenses. Baseline values for subjective refraction and binocular visual functions were evaluated. Nineteen myopic subjects aged 20–26 years (21.59 ± 1.40 years) participated in the study. In this randomized, single-blinded experimental study, visual behavioral performance (VBP) and Ocular Surface Disease Index questionnaires were used for preliminary screening. The purpose of this study was to investigate the influence of different optical designs of contact lenses on binocular vision and visual behavior among young adults. Theoretically, contact lenses change the accommodation and vergence demands of the eyes and directly or indirectly influence binocular vision.
