how about starting with these?

Also, why did the Zoom Focus Eyewear LLC/Trufocus people change the name of their product to Superfocus in October 2010?
Is there any input from any professional groups of ophthalmologists or optometrists that endorse the use of this gadget eyewear? Perhaps most important, have any eye care professionals -- ones that don't hesitate to identify their specific field -- signed off on this eyewear as being truly harmless?

Hi All,
Full disclosure: I am a shooter and I work with Superfocus. I am also one of the moderators of http://shoot.superfocus.com, the online community for shooters who are overcoming presbyopia.
I appreciate the great discussion here about vision needs and shooting, and I would like to present some facts about Superfocus and answer some of the questions posed previously.
In regards to the first question, Superfocus changed its name from Zoom Focus Eyewear LLC/Trufocals in October 2010 as part of a brand renovation. The brand change was inspired by conversations between Superfocus LLC (formerly Zoom Focus Eyewear LLC) and its users, during which a universal customer experience became evident: most reported an “awakening” or an ‘ah-ha’ moment upon trying the glasses. Over and over again, consumers used the words “super” and “super focus” to describe their newfound focal ability.
In regards to the second question, eye care professionals across the country have begun offering Superfocus in their practices. You can see the full list of dispensing eye care providers
here. I am also happy to put you in touch with some eye care professionals who strongly endorse Superfocus.
Recently, Superfocus was further validated by NASA when it certified the glasses for use in space. You can read the full story
here.
In regards to the third question, Superfocus was invented by Dr. Stephen Kurtin as the culmination of twenty years of development. Dr. Kurtin holds S.B. and S.M. degrees from MIT and a Ph.D. in applied physics from Caltech.
Superfocus are adjustable focus glasses (not multifocal glasses) that mimic the focusing action of the human eye. Also, they are very popular amongst shooters. You can read what NRA editor and pro shooter Chip Lohman had to say about them here:

Superfocus allows the user to adjust the focus of their lens instantly. Unlike bifocals or even the most advanced progressive lenses, the region of sharp focus is not limited to a small zone, but instead spans a user’s entire field of vision. There are simply no zones of fuzziness, blur or distortion. The result is a complete solution for presbyopia, eliminating any need to carry multiple pairs of glasses or suffer the negative side effects of bifocals and progressives.
Each Superfocus "lens" is actually a set of two lenses, one flexible and one conventionally firm. The flexible lens (near the eye) has a transparent distensible membrane attached to a clear rigid surface. The space between the membrane and the clear rigid surface holds a small quantity of clear optical fluid. As a user moves the slider on the bridge, the fluid is pushed forward to alter the shape of the membrane, thereby altering the flexible lens. Changing the shape of the flexible lens changes its focus, mimicking the performance of the natural lens in youthful human eyes. Superfocus technology allows users to adjust their focus at any distance and under any lighting conditions. The result: clear, undistorted vision over a wide field of view without any zones or lines in the lens.
The second (front) lens holds the user’s prescription and latches onto the frame, held firmly in place by a patented system of tiny magnets. It is quick and easy to snap off one set of front lenses and replace them with another.
Many shooters have found Superfocus to be an ideal solution for their shooting (and everyday) vision needs.
Happy Shooting,
Caitlin
