Background: 
Adults spend on average 11 hours/day on digital devices and report symptoms of digital eye strain (DES) after 2+ hours (Kaur, 2022). A multicentre assessment was conducted to assess wearer experience and eye care professional (ECP) acceptance of a novel daily disposable contact lens (DDSCL) designed to reduce accommodative burden associated with digital device use.
 

Method: 
An observational assessment was conducted at 23 US sites; ECPs refitted 207 habitual SCL wearers with a novel DDSCL (MDE) (stenfilcon A, CooperVision, Inc.). Wearers rated comfort, vision, and symptoms of DES with their current CLs at the initial visit and again with MDE at 1-2 week follow-up, using agreement/rating scales of 1-5. ECP surveys were conducted post-assessment. Data were submitted from December 2022-January 2023. An analysis was performed on ECP and wearers’ relative satisfaction with MDE vs. previous CL correction.
 

Results: 
207 patients were refit with MDE (mean age 33 years (± 10.0), 65% female). On final assessment, wearers rated MDE higher than their previous CLs for overall vision clarity (4.68 vs 4.50, p<0.01) and comfort (4.53 vs 4.23, p<0.01) and reported reduced frequency of DES symptoms with MDE than with habitual correction (3.41 vs 3.00, p<0.05). 91% were satisfied with MDE at follow-up. 76% agreed that they experienced an improvement in eye dryness while using digital devices with MDE, and 85% said they experienced an improvement in eye tiredness while using digital devices with MDE.

In the post-assessment ECP survey, 100% agreed or strongly agreed that MDE supports digital lifestyles, providing comfort and reduced symptoms of eye tiredness associated with digital device use. 
 

Conclusion: 
These results demonstrate wearer satisfaction with visual clarity, comfort, and symptoms of DES when fit with MDE. ECPs can confidently prescribe MDE for patients experiencing DES as it can help symptoms commonly associated with DES.
