+1, but I'd add that if you want to test whether this is an issue and don't want to shell out for blackout curtains (or are in an apartment where you can't), an eye mask is a good way to go.
After trying half a dozen or so of the $10-20 Amazon eye masks, I sleep with the Manta Sleep eye mask and am quite happy with it. I see a bunch of other masks in the $30 range that also look like solid options.
