Participants were dispensed with the verofilcon A study lenses for 14± 2 days, to be worn for at least 5 days a week and 10 hours per day, while continuing their normal routine of digital device use. Participants rated the lens performance at the Day 14 visit using a 0– 100 (with 100 being best) scale. Ratings were completed at lens insertion, after 6 hours of digital device use, just before CL removal and for overall experience. Participants also completed a 4-point (strongly agree/disagree, slightly agree/disagree) Likert scale-based questionnaire.Results: Thirty-two participants were eligible and completed the study (27 females; age 25.8 ± 6.0 years, ranging from 19 to 40). Overall lens performance ratings at the Day 14 visit (mean ± standard deviation) for comfort, dryness, and clarity of vision were 91 ± 11, 88 ± 11, and 92 ± 9, respectively. Subjective ratings were stable throughout the day with no significant differences after insertion, after 6 hours of digital device use and before CL removal (all p> 0.05). The majority of participants agreed that the study lenses performed well, provided good all-day comfort (28/32; p< 0.01) and good all-day vision (29/32; p< 0.01). Participants also agreed that after ≥ 6 hours of digital device use they were satisfied with CL comfort (27/32; p< 0.01), vision (29/32; p< 0.01) and that the lenses provided good performance (26/32; p< 0.01).Conclusion: Verofilcon A lenses were found to perform well, with high ratings for comfort, dryness and vision that remained high throughout the day, during extensive digital device use.Keywords: digital device, vision, comfort, verofilcon A, lens wettability, contact lenses
