Brief Summary
The goal of the study is to quantify wavefront aberration profiles of the eye with and without contact lens across the visual field. This will enable us to investigate the impact of the aberration on retinal image quality.

Outcome Measures
Primary Outcomes (1)
Mean Wavefront aberrations
The scanning wavefront sensor will be used to collect data. Mean Wavefront aberrations for each trail will be analyzed.
less than 2 hours
Study Arms (1)
Experimental
Subjects will undergo three Wavefront measurements, once with no contact lens, once with a monofocal contact lens and once with a bifocal contact lens.

Eligibility Criteria
Adults with no ocular pathology and uses contact lenses.
You may qualify if:
- A person will be included in the study if he/she:
- Is 18 years or older and has full legal capacity to volunteer.
- Has no ocular condition or pathology, which may impact visual acuity e.g. keratoconus, amblyopia, cataract, macular degeneration;
- Has no active ocular disease or allergic conjunctivitis;
- Is not using any topical ocular medications;
- Is willing and able to follow instructions;
- Has voluntarily agreed to participate in the study by signing the statement of informed consent.
You may not qualify if:
- A person will be excluded from the study if he/she:
- Is under the age of 18 or over the age of 60 yrs.
- Correctable with high contrast logMAR acuity (EDTRS) testing to 20/20 or better;
- Pregnant at the time of enrolment in the study;
- Unable to handle, insert, remove or care for the study lenses;
- Considered by the Investigator to not be a suitable candidate for participation.
