Can you tolerate this penetrating light? or is it my role to distract you? How do I correctly punctuate this line? Maybe the first '?' Should go, be replaced with a comma, or should the the 'o' be O?
Either works, keeping in mind that the latter option makes the second sentence a fragment. I think if you want both questions emphasized, I'd go with two sentences.
If you break it into two sentences it feels like there would be a break verbal break between the two questions. Whereas if you use a comma to separate the questions, it feels like it's all coming out in one breath. If you do use two sentences, though, the 'or' probably should be capitalized.
