Currently there are no data that indicate that starring into close screen contributes to myopia alone. In fact if that hypothesis of lack of blue in indoor lighting that presumably makes it much harder for eye to focus is true, then starring under indoor lighting to the screen could be even protective as the screen has more blue light than a typical indoor light.
In light of that (pun intended) one may need to be careful with twilight-like applications for smartphone that suppose to help with sleep by switching off blue pixels. It could be that while doing so they cause extra risk for myopia.

Sure, lack of blue light might also contribute, but the overall amount of blue in any artificial commodity lighting doesn't rival the sunlight.
- fpoling 11y agoIt is not the amount of light but rather spectral changes that may be responsible for myopia, http://iovs.arvojournals.org/article.aspx?articleid=2127682 http://iovs.arvojournals.org/article.aspx?articleid=2127682
