Trials of the Butterfly Bris attached to sunglasses has shown
excessive and variable distortion of the sun image when nodding the
head. This is perhaps caused by curvature of the sunglass lens. Better
observations were made with the Bris held well out in front of the
sunglasses.

it too busy for my visual taste though and prefer the Butterfly Bris variant 
seen here attached to a pair of sunglasses using a rubber band. This 
arrangement works quite well. Use two pair of dark sunglasses (one over the 
other) to view the bright primary sun images and a single pair of medium 
sunglasses for dim secondary sun images.
