Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Higher order aberrations are imperfects in the eye that affect the quality of image projected onto the retina. Soft contact lenses are made of different materials with different stiffness. This study looks to see if the soft contact lens material affects the amount of higher order aberrations in an eye.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CL first

Subject will present wearing habitual contact lenses for the aberrometry measurement. They will then remove their contact lenses and measurement repeated uncorrected.

OVITZ xwave aberrometer

Intervention Type DEVICE

wavefront aberrometer

Glasses first

Subjects will refrain from contact lens wear on day of the visit. Initial aberrometry measurement will be performed uncorrected. They will be then asked to insert their contact lenses and aberrometry measurements repeated.
