Arms and Interventions

Arm Intervention/Treatment
Experimental: Yung Sheng 55% Color Contact Lens

Device: Soft Contact Lens
Vision Correction

Outcome Measures

Primary Outcome Measures

  1. The effectiveness of corrected visual acuity [3 Months]

    The visual acuity after contact lens correction should be more than or equal to 1.0 at the final visit for each subject. The percentage of successful contact lens correction of visual acuity should be more than 90 % among all subjects.

Secondary Outcome Measures

  1. Lens fitting (Lens position) [Day 1, 1 week, 2 weeks, 1 month, 2 months and 3 months]

    Lens position should be "in the middle of eyes". The successful percentage among all subjects should be more than 80 %. Slit-lamp biomicroscopy will be assessed according to the approved study biomicroscopy CRF.

  2. Lens fitting (Lens movement) [Day 1, 1 week, 2 weeks, 1 month, 2 months and 3 months]

    Lens movement should be less than "1.5 mm". The successful percentage among all subjects should be more than 80 %. Slit-lamp biomicroscopy will be assessed according to the approved study biomicroscopy CRF.

  3. Lens fitting (Lens edge) [Day 1, 1 week, 2 weeks, 1 month, 2 months and 3 months]

    Lens edge should be normal after wearing. The successful percentage among all subjects should be more than 80 %. Slit-lamp biomicroscopy will be assessed according to the approved study biomicroscopy CRF.

Other Outcome Measures

  1. Safety evaluation [12 weeks]

    Incidence of adverse events; Incidence of serious adverse events; The safety endpoint in this evaluation is the rate of serious adverse reactions related to visual acuity loss as well as accompanying slit-lamp findings and other associated observations.
