Detailed Description
The objectives of the study are
- to identify possible reasons for the different comfort and vision experience in Japanese CL wearers compared to Caucasian CL wearers and
- to assess whether the modification of lens thickness in the optical zone results in increased comfort and reduced visual acuity fluctuations in Caucasian eyes.
