I just turned the light on and kept my eyes open for at least 10 minutes. Just turning on the light for a moment or looking at the time on your phone is not enough to stimulate the retinal ganglion cells. You have to keep your eyes open for several minutes. If you consistently do this at a time before you would normally wake up, your clock shifts earlier. You'll wake up earlier even if you don't use an alarm. And you'll get sleepy earlier in the evening too. Does that provide enough information?
