How well do they stay on in a dive mask, when rinsing out?

Previously bought lenses of this type stick on quite firmly but if the inside of the mask is left wet for several hours or if demisting solution is used they may start to slide about a bit but usually there's no problem. These particular lenses ( +2.5) did not stick very well, it may be that being thicker than lenses that I have used previously that they did not lie as flat on the glass so that water could get underneath but they work very well on my sun glasses.
