Scab? Thing between his eyeball and scales keeps growing back?

[Albert Clark]

My unprofessional guess would be that there is an eye issue and it's not really a scab but more a build up of some fluids coming from his eyes since it's both sides in the same location. Maybe there is a mild issue that causes regular discharge but the shedding process irritates it since it can't escape when the eye caps have a gap between layers. Did that make sense? Can snakes need eye drops? Sorry I'm not much help.

Yes Hannah, this makes a lot of sense. Kudos to you for that deduction, very possible.
