According to one source:
On Feb, 3, 2012: 3,872 people reported to have side effects when taking Nicotine. Among them, 10 people (0.26%) have Light Sensitivity.
Which I have not taken the time to validate. However, since we can not post links to other sites, and I have no personal experience with this, my best advice is to pop the question into Google and see what comes up. Based on that so called study, it was a very very small percentage and there seemed to be other variables that may have actually been the cause.
At the same time, it does point to the possibility that you may be one of the very few. What strength are you
vaping at? Maybe try a lower one and see if anything changes.
I know that I can get migraines from time to time that don't cause me any pain, but I get all the other aspects normally experienced like light and sound sensitivity. Usually it's from not enough of my 'ine fienes, but that's just me.
Luckily I've kicked my soda addiction along with the analogs, so I hope not to repeat that experience anytime soon.
