Description

The Sivtsev table is the most common table in the territory of the former USSR used to check visual acuity. The table is named after Dmitry Alexandrovich Sivtsev, the Soviet ophthalmologist (1875-1940), who developed it in 1925. Select a vertical surface you want to pin the chart on, step 5 meters away from it, direct the rear camera towards the surface and start the program. After the table is loaded, you can change its position and size using the control panel or right on the screen with the help of drag-and-drop, rotation (with two fingers) or zooming in/out (with two fingers) gestures. If you want to change the vertical surface, tap the button with two round arrows. You can disable help texts or sound using the corresponding buttons.
