Prospective, Randomized, Controlled Agreement and Reproducibility Clinical Study

Completed · Not applicable

Conditions studied: Digital Acuity Product

In brief

Visual acuity is the relative ability of the eye to resolve detail that is usually expressed as the reciprocal of the minimum angular separation in minutes of two lines just resolvable as separate and that forms in the average human eye an angle of one minute. Visibly Inc. has developed a method for determining a patient's visual acuity electronically via a web-based software system that can be self-administered wherever convenient. This method provides an efficient alternative for people to have immediate access to visual acuity measurements.
