Sides are not adjustable, but it's a six inch area to place your entire
head in there. Focus is managed just like a generic stereoscope in that
the image holder can be slid back and forth for each image, as required.

I have yet to meet anyone who can not use this viewer with their glasses
on. Also, it's a greater magnification than you may have seen, so the
images are easier to enjoy.

The light is above the lenses and provides front lighting from above for
the cards. This adds greatly to the viewing experience IMHO. =)
