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.

1) You have 10 seconds to click on as many abnormal features as possible.

2) After 10 seconds, you will see the areas the other players clicked. If you agreed on a spot, click on it, to "reinforce" that spot. Feel free to use the chat area to discuss. You can toggle off other players' spots if you need to.

3) You can use up to spots, total, but you might not need to use them all. It's also OK if you run out and there are still more abnormal areas.

This is a normal image with no abnormal features seen.
