I have recently bought a new 8x32 FL. And unlike my older 8x42 FL or the 8x32 FL demo model I had while waiting for the new binoculars, this new one tends to irritate me every once in a while with a very intense orange-reddish shine before the binoculars are on my eyes. The only explanation for this, I think, is a too strong coating on the oculars' outermost lenses. I guess it must come from the Lotutec coating? At least, the older versions I mentioned above neither show the red coating nor the irritation described here.
The effect varies and it is most pronounced under bright overcast skies. Also, I think it affects me particularly as I need to keep my regular eye-glasses on while using optics like scopes or binoculars. Thus, there is a gap between the oculars and my eyes that can't be fully closed. So even while using the binoculars, there is at times an orange-red spot at the edge of my vision.
It is rather difficult to get a decent photo of the problem. So, the pictures attached here only partially show the reflection. The bright ring on the rim can go all around on both oculars when conditions are "right".
