Eye charts are often used by health care professionals, such as physicians or nurses, to screen persons for vision impairment. Ophthalmologists, physicians who specialize in the eye, also use eye charts to monitor the visual acuity of their patients in response to various therapies such as medications or surgery.The eye test chart is placed at a standardized distance away from the person whose vision is being tested. The person then attempts to identify the symbols on the chart, starting with the larger symbols and continuing with progressively smaller symbols until the person cannot identify the symbols. The smallest symbols that can be reliably identified is considered the person's visual acuity.The Snellen chart is the most widely used. Alternative types of eye charts include the logMAR chart, Landolt C, E chart, Lea test, Golovin–Sivtsev table, the Rosenbaum chart, and the Jaeger chart snellen chart.Technical Specifications:Power supply: AC100V to 240V, 50/60HzStandard power: Approx. 60WStandby power: Approx. 2WDot pitch of monitor: 0.282mmType of monitor: TFTSize of monitor:19 inchRatio of monitor: 16:9Working distance: 1m to 6.5mRecording methods of vision: Decimal & Imperial fractionControl distance: not less than 8M for maximumInstallation: Table support and Wall mount are all included
