Introduction

In this short study, we will test your eyes’ and monitor’s color and contrast sensitivity. We will also test your ability to detect small changes in images.

You will answer 13 questions. If it takes you longer than 30 seconds to answer a question, please enter your best guess.

Please perform this experiment in an environment with dim lighting. Bright lights and glare on your screen can affect your ability to perceive small differences between images.

Requirements

We are looking for participants with a relatively fast internet connection. This study supports newer versions of Chrome, Firefox, Edge, and Safari.

Finally, we recommend that you make your browser fullscreen and set your monitor’s brightness to between 80% and 100%.
