Summary
This study seeks to quantify digital visual performance and subjective visual acceptance of toric contact lenses as compared to spherical lenses in low to moderate astigmatic patients.
Eligibility Criteria
Inclusion
+6.00 to -6.00 D vertexed sphere power and -0.75 to -1.50 D vertexed refractive cylinder in the right and left eyes Best corrected acuity of 20/25 or better in each eye Self report of at least 4 hrs/day using digital devices Current/established soft contact lens wearer (has worn contact lenses in the past year)
Exclusion An optometrist or optometry student History of ocular pathology or surgery Binocular vision disorder (i.e., tropia, convergence or accommodative insufficiency) Gas permeable lens wear for at least 3 months Presbyopic (based on refraction)
