The VX22 serves refraction rooms in optometry practices and ophthalmology clinics that test vision at 2 to 8 m. Its main argument is connection. An ETDRS chart with automatic scoring covers visual acuity values from 0.1 to 2.0, an Amsler grid supports detecting age-related macular degeneration, and the monitor exchanges data with the rest of the refraction room. One system therefore covers the distance check and the macular screen.
The system shuffles chart sequences to limit memorisation, and anti-aliasing smooths the 23.6-inch display, which shows 1920 × 1080 pixels at 250 cd/m². The test distance is adjustable, and the chart size adjusts to keep the visual angles consistent. A mirror mode suits confined spaces, and a built-in LED provides an external fixation point. The monitor therefore suits a short room as readily as a long one.
A radio-frequency remote works without being aimed at the screen, and the Acuitab tablet app orders tests and retrieves data through two-way communication. The VXbox imports data wirelessly from autorefractors, keratometers, and lensmeters, and exports refraction data to the electronic medical record with one button. The VX65 digital phoropter synchronises with the monitor through optional cables or WiFi.
Ports include RS232, IR, 4 USB, VGA, HDMI and LAN, and a built-in speaker plays media in MP4, AVI and MPEG formats. The unit measures 585 × 46 × 380 mm and weighs 3.8 kg, keeping its profile slim in a busy refraction room. The 46 mm depth leaves the wall or stand free for the rest of the examination equipment.
