Years ago before Jespersen bought them out, Sanderson used to make a hood
that had adjustable had straps - looked a lot like a crew O2 mask. I used
one of those for years with folks that had glasses (bifocals back then). The
closest thing I see to that device today is

The Sanderson hood was almost 15" long and gave a tunnel view of everything
in the cockpit. I could tell if the student was scanning the panel because
to see everything he or she had to move their head slightly. That was the
only drawback, having such a restricted view. This new one doesn't seem that
narrow however.

I've been working on that elusive instrument rating for awhile now,
but I still haven't come up with a very good solution for my view
limiting device.

I need to wear glasses for reading (charts), but otherwise I see just
fine. I wear progressive lenses (for presbyopia) that vary from a
diopter of 2.5 on the bottom to almost no correction on the top. Most
"devices" only let you see out of the bottom of your glasses, which
works for reading but then the panel is blurry. I have to remove the
entire contraption if I want to see the "runway environment".

I've tried foggles, and a "real" wraparound hood. The hood seems to
work the best, but I get a "crushing" headache from wearing the
headset, hood, and glasses. Maybe it's because it's an old style that
clamps around you head!

I've noticed some alternatives on the market including; Overcasters,
Hoodwinks, and one called Viban.

Have any of you had success with a particular type of hood? I would
be very interested to hear your opinions, especially if you also wear
progressive or bifocal lens glasses.

Thanks!
