Often causes the eye to become less responsive.
a. alcohol
b. nicotine
c. adderall
d. cocaine

Technically, all of these can cause double vision and other vision problems.

I'm not really sure what "less responsive" indicates, because it can mean a broad spectrum of symptoms. However, I would answer this with alcohol because it causes your eye muscles to weaken and can include symptoms like involuntary twitching.

Sorry I couldn't provide you with a definite answer, but I hope I was able to help :)
