For near vision assessment, we recommend a tablet of about 10” in size, and Full HD resolution (1920×1200 px). (It is important to choose a model from a well stablished commercial brand, to ensure displays will not be distorted).

A regular monitor is all that is required for a high-quality display of Optonet Vision Unit test. Charts for the assessment of binocular vision will require standard red/blue filters* (available under request).
A screen size of around 23” is optimal for clinical practice. However, a larger sized monitor would allow displaying an increased number of lower VA letters at once.
Full HD screen resolution (1920x1080 px) is required for excellent image sharpness; and IPS technology is ideal for high quality contrast sensitivity displays.
Built-in speakers may also be handy, to hear the bleeps that indicate test changes.
Finally, if interested in mounting the monitor on a wall, make sure a VESA system is incorporated.
