Summary

The purpose of this study is to evaluate whether altering the optical power (in dioptres) of a contact lens affects both vision and lens fit. As the majority of modern contact lens wearers prefer daily disposable soft lenses, the trial lenses used in this study-provided by CooperVision-reflect this trend, representing nearly 80% of the current UK market.

This study aims to generate data supporting the use of contact lenses with powers that do not precisely match a participant's visual prescription (within ±2.00 dioptres) as a viable temporary alternative when the exact required power is unavailable.

At present, there is no published literature in the context of modern contact lens design that compares the fitting characteristics of 'fit-for-purpose' lenses with those of lenses from the same design family that would not typically be selected due to power mismatch.
