Feedback

We’d genuinely like to hear from you.

Two kinds of message are especially welcome: ideas for the app, and corrections to the science. If you study vision — human or animal — and we’ve gotten something wrong or oversimplified, we want to know, and we’ll credit good corrections.

Reporting a scientific correction? A source or citation, if you have one, helps a lot.
