It's whenever he's using his powers (or when the artists have decided they feel like giving him a glowy eye today, though we will ignore that because if we start believing everything they tell is then we'd end up having to concoct ridiculous theories where Cable has a third leg or something just to make it all add up) - levitating something is just the most obvious case. But most of the time it's not supposed to glow, and teen Cable in those chapters is pretty explicitly depowered. So by that standard, a glowy eye in this photos would be pure, canon-negligent fanservice. Not that there is anything wrong with fanservice.
...which photo do you think needs a glowy eye the most? One of the two full-body shots, maybe?
