I Can't Sleep With the Lights On
This is true of me, because the light really bothers my eyes when I'm trying to sleep. I can put on my sleeping mask, but it doesn't block all of the light, and even when someone has the TV on, and I'm trying to sleep, the glare of the TV screen bothers me, and I can't sleep. It is the reason I hate having televisions or computers in my bedroom, because I love having my bedroom dark when I'm trying to sleep.
