Glasses does not fit helmet of the same brand!

For all buyers who think like me, a ski goggles from Cox Swain would be tuned moderately fit on the helmets of the same company, it is said that is not the case. Although unintelligible, but true: one has placed a helmet of Cox Swain and tried also to set up a spectacle of this brand to be seen that the upper edge of the glasses do not conform goes with the end-face helmet cut! (The goggles by Uvex fit here of this radius of curvature much better, even on these helmets from Cox Swain just for info)
Can I therefore not recommend or any buyer should know in the first place. If I had known that, I would not buy the glasses. Incidentally, for the other models of Cox Swain also (I had several different buy)
