Hope that helps to choose the "right frame size".
Moreover - in the wake of the delivery of 65''Panasonic now also a first personal impression as compared to the standard glasses:
Although for the incredible 3D experience suffice the supplied glasses, but where it should be noted that in our 4köpfigen family alone with me the spectacle remains seated on his nose without further auxiliary means. Since all of us fit the size "M" without problems, the other (standard) are spectacles compared seemingly rather attributable to the "L" range.
In addition, determine: The TY-EW sits much better, is more comfortable to wear (no pressure points) and the viewing experience is (as the side protected) subjectively better.
Small gripe with all models (hence no 5 star): For my taste, the lens could be larger overall. Especially people with glasses the size means that you can see through above or below the glasses (and may therefore less good eyes "wander" can). Well, maybe come at some point new (Univeral-) glasses, absorb the ... but until then I can live with the TY-EW also super good.
