Interesting article about a new study:

> The study, led by researchers from UNSW Sydney and published in eLife, found that the pupils of people with aphantasia did not respond when asked to imagine dark and light objects, while those without aphantasia did.

Thats interesting, I never would’ve thought the pupils would react just as if it was seeing dark or light in the actual environment! Gonna have to test it out for fun.
