Southern College of Optometry100 enrolled

Overview

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.

Inclusion Criteria: * Willing and able to provide informed consent * Adults \> 18 years old regardless of gender, race, or ethnicity * Habitual single vision soft CL wearer for at least 1 week in any modality. Exclusion Criteria: * Multifocal soft CL wear * GP or ortho K wear in the last 3 months. * Active eye infections and inflammations. * Current use of ocular medication.

Outcomes

Primary Outcomes

Mean change in HOA with and without contact lenses

Measure HOA with contact lenses. And then measure HOA without contact lenses.

Time frame: Within the same study visit, measurements will be taken 15 minutes apart to allow for tear film to return to homeostasis after contact lens insertion/removal.

Secondary Outcomes

Correlation between contact lens modulus and changes in HOA with and without contact lenses

Evaluate correlation between the lens modulus and changes in HOA

Time frame: Within the same study visit, measurements will be taken 15 minutes apart to allow for tear film to return to homeostasis after contact lens insertion/removal.
