    Yes, poor light can cause eyes strain.When you are in a poor lighting, your eyes will do a lot of job to adjust the light. First, the rod and cone cells on the retina begin to produce more light-sensitive chemicals. Second, the iris muscles relax, which causes the opening of your eye, the pupil, to become very large. So when your eyes are working this hard for a long period of time, it will cause eye strain.

You should take great care of your eyes. You'd better be in the room with bright light when you see something. Or else, your often eye strain will cause your eyes problems.
