I'm sorry to hear about your intermittent episodes of light sensitivity!
In view of your associated symptoms of associated nausea, tightness in the neck and head, you should get reviewed by your ophthalmologist or neurologist as these symptoms are consistent with migraine headaches.
Your physician can help to review you to ascertain the likely reason for your light sensitivity, and to exclude other causes such as dry eyes, incorrect spectacle prescription, or an organic disorder of the eye.
