Brief summary

At the New England College of Optometry in Boston, MA, subjects ages 18-65 who have received or are receiving treatment for refractive error who choose to enroll in the study will be evaluated using subjective refraction and automated refraction, by way of the QuickSee Plus refractor. Subjects will then be randomized into one of two treatment plans: receive glasses from automated refraction first then subjective refraction second, and vice versa. After one week of wearing the first pair of glasses, patient preferences are assessed, and glasses are switched. After a week of wearing the second pair of glasses from the alternate measurement method, patient preferences are again assessed. Patients may then decide which pair patient like best. This is a triple blind, case-crossover clinical trial.
