Traditionally displayed in clinics and ophthalmology offices, the chart consists of rows of letters decreasing in size, allowing practitioners to determine the smallest line a person can read at a specified distance—usually 20 feet or six meters. How the Snellen Chart Works The core principle involves presenting a series of letters (optotypes) that are designed to be easily Pocket Snellen Chart Printable 6 recognizable and standardized in shape and size.
