Ramires was shown a second yellow card for high feet and Christian Benteke then followed for the same offence.
Lambert felt both red cards were harsh but was most annoyed by the decision to show John Terry only a yellow card for a foul on Yacouba Sylla.
"I don't need to speak to the referee, you just get yourself into trouble," said Lambert, whose side remain in the relegation fight as a result of the loss.
"I thought the whole game the referee was poor. When John Terry takes Sylla down, the full-backs are not getting back there - he's the last man. The referee has to see that. Sylla is through.
"The referee should have seen that the way I saw it or the way 40,000 saw it: Sylla's through on goal.
"The referee should have done better than what he's done."
