Custom DeluxPI
Researchers at Ulster University’s Centre for Optometry and Vision Science, recently conducted wearer trial studies to evaluate the reception of the new Custom DeluxPI . 52 presbyopic participants, aged 50 to 71, were recruited and blind to the type of lens worn.
The study had participants wear DeluxPI for a two week period to review how they are received in general and also consider how they perform in certain visual activities. The outcome of the trials revealed that the new Custom DeluxPI garnered exceptional satisfaction ratings among patients.

custom all purpose
Researchers at Ulster University’s Centre for Optometry and Vision Science recently conducted a wearer trial to evaluate the reception and performance of the Custom All Purpose lenses. The study involved 51 presbyopic participants aged 50 to 71, who were unaware of the specific type of lenses they were testing.
Participants wore the All Purpose lenses for a two week period, assessing their general reception and performance across various visual activities. The trial results revealed high levels of satisfaction, with the lenses achieving an impressive average score of 4.5 out of 5 when participants were asked to rate their adaptation to the glasses.
The trial included participants with prior experience using high performance, branded lens designs, further validating the strong performance of the All Purpose lenses. The study showcased the lenses’ effectiveness across all key areas of progressive vision: distance, intermediate, near, and dynamic vision. These findings underscore the capability of the Crossbows Custom All Purpose lenses to deliver an excellent visual experience at an entry-level price point.
