Metropsis research edition

A complete toolbox for psychophysical assessment of visual function

Fast, accurate and more sensitive than standard tests

For normal, defective, paediatric, ageing and low vision populations

Metropsis is a complete toolbox

Metropsis is a complete test suite suitable for clinical, pre-clinical, drug trials, screening, sports science, applied vision and human factors research. Choose from a wide range of tests, including protocols designed for normal, paediatric, ageing and low vision populations – or we can develop a custom test  for your project.


Easy screening of Best Corrected Visual Acuity using the familiar chart.

Single Optotype

A finer scale of letter sizes allows detection of more subtle changes in visual acuity.

Landolt C

Especially suitable for pre-readers, illiterates and subjects unfamiliar with the Latin alphabet.

Gabor Patch

For a more detailed characterisation of spatial visual abilities.


Quick, easy and efficient to score, measures contrast acuity using customised spatial frequencies.

Flicker Test

Temporal contrast sensitivity “Flicker Test” is informative of light and dark adaptation abilities.

Depth Discrimination

Depth discrimination is an informative measure of binocular vision.

Cambridge Colour

Rapid screening, or full assessment of changes in colour discrimination.

Low Vision Colour

Uses a larger stimulus size which is more suitable for patients with low vision.

Universal Colour Test

A discrimination task which is simple enough even for children as young as 5 years old.

for faster more precise assessment of visual function

Metropsis is more sensitive than standard charts: ideal for investigating diseases of the eye and brain, as well as secondary effects of systemic disorders, such as cardiovascular disease or neurological function.

The research edition includes Metropsis Display++ technology (the screen displaying the ETDRS chart above) with a unique integrated sensor system, enabling the display to self-calibrate in real time. So you can be sure that your results are reliable and repeatable – even when performing long-term studies using multiple Metropsis systems across different sites.

based on trusted technology
