We were going into EGE; weather was good with bases approximately 15000 feet. As we approached RLG we were to maintain 13900 feet passing RLG and cleared the LDA Rwy 25. We were IMC until approximately 15000; we broke out and were VMC as we neared RLG. Crossing RLG we were VMC with ground contact. We descended over 300 feet below the MEA; realized it and came back up to MEA before VOAXA the next waypoint.What happened? We had briefed the high terrain during our cruise and reviewed the arrival and approach. I think for some reason; the terminology of the clearance and going into VMC; seeing the terrain; made me think the next section MEA after RLG was below 13900 feet. I looked at the plan view of the approach plate and missed seeing VOAXA; I then looked at the profile view and saw 12900 feet for AGULA; the waypoint after VOAXA. I told the Pilot Flying our next altitude was 12900 feet; we descended but realized/double checked that was incorrect and climbed back up. Center did not mention anything or that they noticed our deviation and told us to switch to tower approaching AGULA. The rest of the approach was normal.It was my error; I'd like to think I am a very careful and safe pilot but this did happen and I've been going over it again and again. I will be more vigilant but I also think the chart is cluttered at VOAXA. I know every waypoint can't go into the profile view but I think if VOAXA had been in the profile view I would have not missed the correct MEA for that section. I'll also scan/confirm FMS waypoints and altitudes as well. Finally; as we normally do on SIDs & STARs or any altitude change; confirm with the other pilot our next altitude restriction as early as possible.
BBD700 First Officer reported descending below charted altitude on approach to EGE; citing lack of chart clarity as contributing.
