Perhaps some brands that make both helmet and eyewear (like Oakley or Rudy Project) make theirs compatible with each other, but anything else is likely to be pure luck. Maybe if you post which model your glasses are, someone here might have a helmet that they fit into, but otherwise I would suggest bringing them into a shop and testing them on various helmets.
