I can understand why you might be worried about this: if they're set light reflections, then doesn't that sorta break the fourth wall?
The thing to keep in mind though is that the audience doesn't know that; these could be reflections from any light source in the world of the characters, but the audience probably won't even think about it anyway.
Also, as David said, many cinematographers will go out of their way to make sure those reflections are there. For example, in my own work, I've found that not having these little eye lights often results in the eyes looking a bit lifeless, especially with brown-eyed subjects. So don't worry about it, no one will look at this as a mistake, and if anything it will probably make your image better.
