Brief Summary
The purpose of this study is to evaluate how visual acuity assessed with Peek Acuity (a cell phone application to check visual acuity) among preschool and school-aged children 3 to less than18 years of age (1) compares to the standard visual acuity exam in the ophthalmology clinic and (2) performs as a screening test for ocular abnormalities that warrant referral for an eye exam.

Outcome Measures
Primary Outcomes (3)
Sensitivity of screening with standard exam vs. Peek Acuity for referral to further medical management
Children screened positive for visual deficit by standard exam will be deemed true positives; any true positives not identified by the Peek Acuity application will be deemed false negatives. Sensitivity is calculated by true positive population divided by the sum of true positives and false negatives
Visit 1 (up to 30 minutes)
Specificity of screening with standard exam vs. Peek Acuity for referral to further medical management
Children screened negative for visual deficit by standard exam will be deemed true negatives; any true negatives not identified by the Peek Acuity application will be deemed false positives. Specificity is calculated by true negative population divided by the sum of true negatives and false positives
Visit 1 (up to 30 minutes)
Accuracy of screening with standard exam vs. Peek Acuity for referral to further medical management
Visual acuity score determined by Peek Acuity will be compared to the score from standard exam to determine accuracy where the score from standard exam is the accepted value
