Inclusion Criteria: * Subjects must be 7 years of age and older * Healthy subjects with no known ocular trauma, no surgery, ocular disease or pathology that would prevent obtainment of best correctable visual acuity to 20/30. Exclusion Criteria: * Refractive error greater than (+)/(-) 6.00 diopter, or astigmatism greater than 1.50 diopters. * Known ocular (corneal, lenticular, vitreal, or retinal) pathology that may limit best correctable visual acuity.

What they're measuring

To compare the best visual acuity and refraction results using the First Sight Refraction System to standard auto-refraction in subjects with hyperopia.
