 The latest machine for eyeglasses prescriptions.

I heard the other day there was a new machine
for eyeglass prescriptions.

Evidently the patient looks into it at an
object (say a small model house) and the
machine determines from this just the type of
glasses reqd.

It can determine Cyl, Sphere & prism with
just one zap.

Has anyone heard of this, and can he supply a
name so I can check it out?

Please help, Peter

Autorefractor

http://en.wikipedia.org/wiki/Autorefractor

It's not new.

It is not as accurate as actually putting lenses in front of your eyes and
asking which is better, 1 or 2. A lot of OD's use it to get a starting place
for the exam.

Thanks, why then are optometrists still using
the old machine requiring manual selection of
lenses?

I have Sphere/Cyl adjustment and I get
varying results from different optometrists.

I have some friends back from overseas, and
they order their glasses there because this
"autorefractor" device gives excellent and
automatic results.

yeah. its called an autorefractor. they've been around for years.
they don't control for accommodation on the part of the patient very
well.  for example, kids who are slightly farsighted oftentimes
autorefract as myopes.

they are nice to have as a reference or to help sort out cylinder axis
but there's NOTHING better than a good manual ret.

because they are inaccurate.

well you'd get WIDELY varying results from an autorefractor.  they are
getting better, but still they are inaccurate and serve only as a
useful reference to a good manual refraction.

in some Asian countries they will sell you glasses based soley on a
autorefractor reading. bottome line is you'd end up with a lot of
glasses laying around that don't work very well.

I find it useful to think of it this way.  An autorefractor measures
the optics of the eye, and therefore what the eye sees.  The
subjective refraction measures what the patient sees, i.e. after brain
interpretation.

Solution:

Device first measures refraction and then t changes lenses in front of
eyes and asks
you "that better or that ?" like when you call you bank it asks you
questions.

To write software for that device - couple of weeks it will be done.
It will do the  job even better then OD, it can work slower then some
women in the rush
for grossery shoping
How do you like that perspective?

Then OD brainwash that brain like in case of that post about 13 old
kid
who are pushed into glasses with OD who wants more clients.

Lena?  Were you{*filter*}d by an optometrist or other vision care
professional?

Seriously.  Were you?

If so, then ... wouldn't law enforcement and a psychologist's office
be a more appropriate venue for your hatred than this forum?

Ya' see: this forum is SCIENCE.med.vision.  All you bring is wrath,
scorn, hatred, bitterness, and resentment.

No information.

Time to seek professional help.

Do any of the big name opticians in UK / Ireland use that machine? I
have only ever had to put the frames on where they slot in and out
different powered lenses.

Why would you need something like that?
Every OD's has "machine" which measures
refraction automatically the name of   "machine" is "auto
refractor" (USA) or "auto refractometer"(some other countries)
The receptionist who worked yesterday in the grocery story push just
one button and device makes and prints the measurements (astigmatism,
refraction, average  ) . Also it measures parameters for contact
lenses.
Copy and paste - it is the  prescription.
If you are interesting you can ask about reading of the device.

Then the OD looks on that printed "receipt" and sticks the different
lenses.
Around +0.5 -0.5 of what the devise printed.
Another manipulation with one button devise.

Easier even  then your cell phone which has "menu".

I'm sure many of those places have such a machine.  It's often used for
brand new patients, those who have just had eye surgery and people who
temporarily can't see.  It gives the doctor a starting place for
testing.  Since they don't work well, no competent doctor would rely on
them for issuing a reliable prescription.  I've had one used on me
twice, both times after eye surgery.

Dan they use it every visit to OD

I don't use one.  I use a retinoscope.  It's quicker and more accurate.
