Yep, learnt about the contact lens stuff as well. But there is always a risk. Some goon might not know the rule and not allow the bottle. You throw it away, fly, arrive at the customer, you have stay at their office for the rest of the day, shops are now closed and you do not have your contact lens cleaning liquid. Therefore I still use small containers, just to minimize my risk.
The whole restriction to 100ml is bogus anyway. The rational being that if you manage to get dangerous stuff on board, if will be a relatively small amount (they do not test any of the liquid after all). Never mind that you could just split the liquid to multiple containers and even have passengers as partners to bring more of it. It truly is security theater.
