Brief Summary:
This is a multicenter study to evaluate the clinical performance of the SynergEyes A2 lens in patients with refractive errors with or without astigmatism.

Condition or disease Intervention/treatment Phase
Refractive Errors Astigmatism Device: SynergEyes A2 Hybrid Contact Lens Not Applicable

Detailed Description:
Hybrid contact lenses have been previously shown to be a safe and effective method to correct refractive errors with and without astigmatism. The hybrid contact lens design may provide greater visual acuity and comfort than other soft or rigid gas permeable (RGP) lenses currently available. The purpose of this study is to confirm the design of the SynergEyes A2 lens by evaluating clinical performance and, if necessary, modify certain lens parameters in order to optimize lens performance. Objective and subjective parameters will be used to evaluate the lens.

Arm Intervention/treatment
Experimental: SynergEyes A2 Hybrid Contact Lens Device: SynergEyes A2 Hybrid Contact Lens
SynergEyes A2 is a hybrid contact lens cleared by the US Food and Drug Administration (FDA) for daily wear correction of up to +20.00 and -20.00 in eyes with astigmatism up to 6.00D and for presbyopia.

Primary Outcome Measures :
  1. Confirm current SynergEyes A2 lens design by evaluating clinical performance using objective and subjective parameters [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Determine the best method for fitting the SynergEyes A2 hybrid contact lens [ Time Frame: 6 months ]
