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 24”-27″ 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 (1920×1080 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.

The Optonet Vision Unit also offers the option of displaying VA and binocular tests in a polarized version for those who have a passive 3D monitor. However, passive 3D monitors are no longer available in conventional computer stores, they are only made to order in China and their price is higher than a conventional screen. For more information, please contact Optonet.

Near Vision


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).
