Alexis hit the nail on the head, this for me is the single most challenging situation to find oneself in, particularly if it is a target bird you are finally seeing after months of planning, a long haul flight, a knackering walk, and then locating something on call in steamy dense forest!

Apologies for the slight diversion, but does anyone have a suggestion to reduce fogging of glasses and/or binocular oculars when looking at an acute angle in rainforest?
I suspect the issue relates to the size of the surface area of the glasses and the combination of sweat and high humidity - would a smaller "reading glasses" type pair be more appropriate (even with the limitations of a reduced fov being in focus? Is there an anti-fogging spray which can be applied to prescription glasses?
Kind regards, Daniel
