[X-Men] How close does the ruby quartz need to be to fully negate Cyclops' beams?

His eye beams produce a red color, so when he wears non-wrap around sunglasses to block it, we should see the red light from the side unless the quartz fully stops the portals from being created. When he goes to remove his glasses, then the portals open. So how far away does he need to get them to do that?

Ruby quartz is, quite simply, impenetrable by Cyclops' beams. If you wear ruby quartz armour, you won't feel anything when his optic blast hits you.

His glasses don't negate his powers, they just block them. The lack of glow around the edges is down to one of three possible factors:

1) It's there; it's just a failure of the art.

2) Cyclops is an incredibly focused individual, and that extends to always keeping his eyes in line with his head. No matter what absurd outfit Gambit or Shadowcat may be wearing today, he never, ever, gives side-eye.

3) It's been established that Cyclops' inability to control his powers is primarily psychological. With the glasses in place, he is reassured of the safety of those around him, and relaxes enough to switch the beams off.
