I did some research and found another possible solution, amber sunglasses meant to block blue light. A popular option on the net is:

Aside from anecdotal reviews, there are some studies showing possible effectiveness:
http://www.ncbi.nlm.nih.gov/pubmed/20030543 "At the end of the study, the amber lens group experienced significant (p < .001) improvement in sleep quality relative to the control group and positive affect (p = .005)."
http://www.ncbi.nlm.nih.gov/pubmed/22850476 Basically, looking at tablets and/or bluelight (wavelength 450-495 nm) at night, which suppresses melatonin production considerably, compared with blue-blocking glasses.
http://www.ncbi.nlm.nih.gov/pubmed/21552190 A similar study to above, where orange-tinted safety glasses where used to remove the melatonin suppression effects.
Has HN had any experiences with blue-blocking lenses? Does it help, or is it placebo and/or nonsense?
Cheers.
