Most nights (and when I nap in the afternoon) for the past couple years, I use an iPad to read websites and Instapaper saves for 15-30 minutes in bed before I go to sleep. After that ~15 minutes, I'm out like a light. I've never previously been able to get to sleep as quickly, reliably, and easily. Sample size of one and all, but I definitely haven't noticed any negative impact on my sleep. If anything, I'm fairly confident that my newly-backlit reading habits have actually helped me get more sleep.
