Introduction

This is a photo of the inside of the eye. Your task will be to label eyes as healthy or unhealthy with respect to diabetes as part of a research study.

You will have access to samples of normal and abnormal eyes to compare against. In the game, you can access these with the purple tabs on the right.

This task is difficult, but all good faith efforts will be accepted. Please answer both questions even if you are not sure.
