RESORY
EBENEZER BARNARD Market Place Cirencester Glostershire, Jeweller do hereby
declare the nature of this invention to be as follows:-
An improved instrument, whereby lenses, fixed at a normal reading distance, from
printed matter such as newspaper or other type, shall by the use of a disc, cylinder,
pivot, or other means, be made to revolvo before both eyes of a person who shall look
through two eye openings shaped something like an Opera Glass, so that the proper
lenses may be readily ascertained, and most easily determining the correct sight or
power of lens required by a person selecting a pair of spectacles Folders or Eye
Glasses, which instrument is to be called The Opsiometer.
Pairs of lenses fixed in a band of linen or other flexible material are made to revolve
on cylinders or rollers before both eyes either simultaneously or (the band being in
two strips) each strip with its lenses may revolve independently of its fellow strip, so
that persons whose eyes are odd, or of unequal power may thus be correctly suited
with a pair of spectacles Folders or Eye Glasses, the cylinders or rollers will thus
revolve with both strips of the band simultaneously bringing a pair of lenses of the
same power before the eyes or one strip be detached from its fellow and a pair of
lenses of unequal strength be brought simultaneously before the eyes by means of
The Opsiometer.

page_text: EBENEZER BARNARD Market Place Cirencester Jeweller, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
An instrument in the shape of a box a which may be mounted on a tripod stand or
on a nest of drawers containing a stock of spectacles, the said box at one end has two
eye pieces like an opera glass the other end c hinged or jointed or slides out so as to
present in a line with the eye pieces, at a normal reading distance a piece of printed
matter d, inside the box close to the eye pieces pairs of lenses E both concave, and
convex, fixed in bands or strips of flexible material, are made to revolve on rollers
or cylinders before both eyes, either simultaneously, or, (the pairs of lenses being in
two bands or strips, one of each pair in each band) each strip with its lenses G may be
detached & revolve independently of its fellow strip, so that individuals whose eyes
are odd, or of unequal power may revolve first one band of lenses to one eye, then the
other band to the other eye, as well as ordinary people, who would revolve them in their
pairs simultaneously. By noticing the numbers fixed on the strip near each lens
persons would thus easily and correctly be suited with a pair of spectacles or eye
glasses. The jointed end of the box where the printed matter is fixed up, is made to
be removed, or fall down if required quite out of the way of the vision, of a person
requiring concave spectacles, as they must look at distant objects, to test the proper
lens required.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is,
That it is an improved way of determining the number or sight of a pair of
spectacles, or eye glasses, required, firstly by an ordinary person, secondly by a
person who has eyes that are odd or of unequal power and thirdly by a person
requiring concave spectacles or eye glasses.
