It wasn't pressurized to sea level pressure. The interior pressure was much lower and they compensated for that by having more oxygen in the mix. They openly say that parts of the lander hull were nothing more than a few thin aluminum sheets that a man could poke holes in with their hand. It didn't need much overall strength because it was only designed to operate in a vacuum.
If the pressure inside of the lunar module was 1/5 that of Earth, would that mean the astronauts breathing would be affected? Go into a room and begin sucking out the air, I bet soon you'd become lightheaded. I'm no doctor but that's my thinking on that theory. Yea, it's feasable that the craft could withstand 1/5 atmosphere, but could the crew?

5lbs psia at 100% oxygen.
