All,

I just had an eye exam, during process my Optometrist performed a
"Pupillary Dilation Test".

My Optometrist performed some tests and told me that I have 1.75 on my
left
eye and .75 on my right eye, she conveyed me that she is going to do
the
'Pupillary Dilation' test.

My Optometrist put some drops in to my eye, and asked me to hold on
for a while, in the meantime, salesperson in their shop started showing
me
glasses and frames, by the time I picked my glasses and frames ( since
I have
the drops on my eyes it was very irritating to me to do the
selection.),
Optometrist started performing tests.

At the end, Optometrist told me 0.75 on my left eye and nothing for my
right eye.

my question is, Do I need to keep my eyes closing during the dilation?
Was it proper that they asked me to pick glasses and frames during
dilation?
Did they performed the procedure right?

Highly appreciate your response.

Thanks
Nambi.

Don't know what is meant by 1.75 or 0.75, perhaps your refractive
error.

Pupils are usually dilated to allow better viewing of the retina and
other structures inside the eye. Although it is uncomfortable, it is
important for detecting eye disease. The pupil dilating drops also
relax accommodation and may allow for more accurate refraction. Since
the refraction seemed to have changed follwing dilation, it was a good
thing you had it done.

You don't need to keep your eyes closed, but may want to wear
sunglasses as the dilation will make you light sensitive. Pupils are
dilated by instilling drops, waiting for the drops to take effect and
then doing the tests that are best done with dilated pupils, so the
procedure you had done sounds right.

Showing you frames while waiting for the dilation drops to take effect
was not improper, it saves you some time. If you don't want to get
your glasses from your optometrist or if you couldn't see well enough
to select them, you only needed to speak up and either return at
another time or go to another place to select frames.

Dear Nambi,

Subject: Pupil size.

It is not possible to determine what the numbers are that you provide.

I would suspect that they are a measure of your refractive status.
If you have a prescription -- you will find the numbers there.

The normal range of pupil size runds from 2 to 8 mm.

Best,

Otis

The size of a dilated pupil would be about 8 mm, i.e., wide open.
