How does BiOptic
Driving Network make money?
We are run by
BiOptic Drive Ltd, a registered not for
profit organization, and our
mission is published here.
Like any
organization, we have to raise money to pay
for deliver of our services, despite our
most efficient efforts to keep running costs
to a minimum. We don't make a profit,
and our costs include telephones, faxes,
letters, literature, etc. We rely
mostly on public donations,
made here.
BiOptic
Driving Network has also received a small
number of grants and corporate sponsorships,
but still needs modest advertising on our
website.

BiOptic
Lenses
A BiOptic is a lens system with a telescope attached
to a pair of glasses, above (BTL is below) one's normal line of sight. This
allows a trained user the opportunity to detect objects or movement
within his/her driving scene using the wide field of view available through
the regular spectacle lens and to resolve fine details such as road signs
and traffic lights by glancing briefly and intermittently into
and out of the miniature telescopic unit. BiOptic lens systems used for
visual assistance in the
driving task are available in a number of different styles, sizes, and
powers: the latter most commonly ranging from 2X - 5.5X ( " X "
referring to the strength or power of magnification of the telescopic
unit).
It was William Feinbloom, O.D. who coined the
name "BiOptic" and the abbreviation BTS in the 1950's, when he
first designed the lens. He used the abbreviation BTS for
"BiOptic telescopic system" Dr. Feinbloom defined a
BiOptic as "a bi-visual optical system which mounts a miniature
aperture telescope in the superior portion of a carrier lens enabling the
user to rapidly change fixation from the carrier lens to the telescopic
system." More information may be found in Dr. Feinbloom's
many publications, in professional journals published during the 60's, and
70's, until his death during the 80's. He first reported on the BiOptic in 1958. Also, Schapero's Diction of Visual Science defines
"a bi-visual system consisting of a small aperture telescope to magnify
distant objects mounted in a portion of the patient's normal
distance correction lens."
Some jurisdictions in the US restrict the power of the
telescopes permitted. Of course, not all BiOptics are used for driving.
The use determines the power, working distance and location on the carrier
lens.
