I have these on my ray bans for 2 years now and and they
work great. You can trim the lenses with scissors to make
them fit perfectly. Charts and instruments are no problem.

I note this seemingly great idea advertised @ $79.95. Getting older I now
need some magnification when reading charts and find it a real pain changing
several times per trip between my RAY BANS and 1.75 readers with my headset
on. Anyone tried this product? Your experiences, or is there another
better product? Thks, Art
