High Performance at Entry-Level

We are thrilled to unveil the wearer trial results for our Custom All Purpose progressive lenses — an entry-level design that is delivering outstanding comfort and performance to wearers.

As part of our commitment to Innovate. Together., we worked closely with Ulster University’s Centre for Optometry and Vision Science to independently evaluate the real-world performance of Custom All Purpose. Their findings confirm what we have long believed: high-quality visual solutions can be accessible to all.


FOREWORD

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 over a two-week period, assessing their general reception and performance across a variety of 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 rated their adaptation to the glasses.

Furthermore, participants were asked to rate their overall satisfaction with the spectacles, resulting in another strong average score of 4.35 out of 5. These results highlight the positive reception of the lenses among wearers.

Notably, 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.
