Twenty-five myopic habitual soft contact lens wearers (aged 20– 40 years, corrected visual acuity ≥ 0.8, CISS < 21) wore three lens types in random order: single vision (SV), center-near multifocal, and myOK Vision anti-fatigue lenses while performing a 10-minute digital task at 40 cm. Measurements included visual acuity, contrast sensitivity, accommodative lag, near point of convergence, ocular alignment, pupil size, tear film stability, visual function, CISS and DEQ-5 questionnaires.Results: There were no statistically significant differences in distance and near visual acuity or contrast sensitivity among the three contact lenses (p > 0.05). The myOK Vision lenses provided better horizontal alignment stability but resulted in higher CISS fatigue scores than the multifocal lenses (p = 0.011), while DEQ-5 dryness scores showed no significant differences (p = 0.426). Center-near multifocal lenses improved near point of convergence and accommodative facility (p = 0.01), supporting convergence stability. No significant differences were found in horizontal alignment and accommodative lag, multifocal lenses showed a trend toward higher lag during tasks.Conclusion: Contact lenses with different optical designs maintained good visual quality during short-term near tasks; however, slight differences were observed in CISS subjective scores and binocular visual performance. The iDSCN multifocal lenses effectively reduced CISS scores and improved accommodative sensitivity and convergence stability. In contrast, the myOK Vision aspheric lenses exhibited advantages in phoria stability but were associated with increased CISS scores. It is recommended that future lens selection take into account users’ gaze habits and individual needs to enhance visual comfort and ocular health.Keywords: digital eye strain, aspheric design, multifocal lenses, accommodative lag, anti-fatigue contact調節遲滯多焦點鏡片非球面設計數位眼疲勞抗疲勞隱形眼鏡accommodative lagmultifocal lensesaspheric designdigital eye strainanti-fatigue contactthesis
