Lens Fitting Evaluation of CooperVision MyDay™ Compared With 1-DAY ACUVUE® TruEye® and DAILIES TOTAL1®

The aim of this non-dispensing study is to evaluate the fitting performance of MyDay™ 8.4
base curve, especially for flatter corneas, and compared it with 1-DAY ACUVUE® TruEye® 9.0
base curve and DAILIES TOTAL1® 8.8 base curve in a range of spherical powers.

Inclusion Criteria:

- Is between 18 and 40 years of age (inclusive)

- Has had a self-reported visual exam in the last two years

- Is an adapted soft spherical contact lens wearer

- Has a contact lens spherical prescription between -4.00 to - 6.00 and higher than
-7.00D (inclusive)

- Has a BFS (Best Fit Sphere) that is higher than 8.2 measured and calculated by
corneal topography

- Can achieve best corrected spectacle distance visual acuity of 20/25 (0.10 logMAR) or
better in each eye

- Can achieve a distance visual acuity of 20/30 (0.18 logMAR) or better in each eye
with the study contact lenses

- Has clear corneas and no active ocular disease

- Has read, understood and signed the information consent letter

- Patient contact lens refraction should fit within the available parameters of the
study lenses

study lenses

either eye
