GoCheck has developed and deployed a home-based visual acuity test that may be used in-office or in residence. The test methodology utilizes modified ATS and ETDRS protocols with Sloan optotypes, crowding bars and sophisticated algorithms. The objective of this study is to determine if the results of the GoCheck visual acuity test performed in an office setting correlate to the same testing when implemented in the residence
