Dear Lady,

You can convert your script to spherical equivalent by taking
1/2 the astigmatic part, and adding it to the "spherical".

Specifically, for the left eye:

0.75 / 2 = 0.375

-0.5 - 0.375 = 0.875

You can round this to -1.0 diopters.

You prescription is weak. If you checked your
Snellen you could probably read the 20/30 to 20/40 line
with no lens.

You can talk to your OD about this issue.

if you live in the US this practice is illegal. after you are fit in
a brand of CL that work for you (meaning that they fit your eye well,
that they are comfortable to you, and that they provide good vision),
federal law states that the eye doctor MUST provide you with a written
prescription. you can take your prescription and purchase the
contacts where ever you please. without a written prescription, you
will be unable to obtain the contact lenses from any reputable
source. some internet businesses used to sell them without a
prescription until a couple of years ago but now they are liable under
the same federal law to stiff penalties unless they can verify a
prescription from your doctor.

just tell your eyecare provider that you prefer the non-toric
spherical lenses and they should give you a prescription-- provided
that the lens brand you want did in fact fit your eye appropriately
and that your exam wasn't such a long time ago that your prescription
might have changed. choosing a satisfactory contact lens brand is
something you need to do properly within a short time of your exam.

what brand of toric are you wearing? many brands of toric lenses are
less expensive than Acuvue Oasys is.

Dear Lady Nuss,

To convert to spherical equivalent (left eye), just do this:

Take 0.75 / 2 = 0.375

Then add to 0.5, or

-0.875 diopters.

You can round this up to -1.0 diopters.

This is a very low-power prescription. With no lens
you probably have 20/30 to 20/40 vision.

A -1.0 should work.

Check with your OD about this issue.

Dear Friend,

As previously posted on sci.med.vision, this prescription
can be converted to spherical-equivalent.

Just take 1/2 the astigmatic value, and add it to the
"spherical" component.

0.75 = 0.375

So:

-0.5 -0.375 = -0.875 spherical equivalent for your left eye.

Both these prescriptions are very low in strength.

You visual acuity is probably about 20/40 or so.

As one OD suggested, you could "round" the spherical-equivalent
to -1.0 diopters, and have 20/20 vision.

You should talk to your OD about this possibility.

I am in Canada and have bought prescription lenses online and you do not fax
your script to them, you just fill in the fields required. My lenses were
fitted by an optician and my eyes have been examined by an optometrist, I
have also tried all kinds of trial lenses.I was fitted with both regular
spherical and toric lenses fitted and at the time (2 months ago) I decided to
go with the toric. I now want to go back to the Oasys, because of comfort,
but don't remember the power I had in my left eye (my right was a -1.00) and
all I have is the toric lens package. I thought based on my script for the
toric lenses it could be figured out in a regular sphere power so I can order
them online. I don't need another eye exam it has only been 2 months. It
seems getting lenses in Canada may be a little different.

You can't buy lenses online without a valid prescription (you'll have
to fax a copy to them before the order will be completed).

The optometrist is being paid to examine your eyes and give you a
prescription. You don't have to buy contacts from him.

You can have it filled anywhere if the CL Rx is current. Many doctors have
competitive fees for replacement lenses, along with discounts on glasses if you
purchase both from the same provider.

Only through an eye doctor. Some states allow opticians to fit CLs, but the
starting point is always with an ophthalmologist or optometrist.

I did try Acuvue Oasys and O2 Optix before going with the toric and they
worked and were comfortable. I don't have the packages fromthem however to
view what power they were, I only have my toric packages. If I ask my eye
care provider he of course will want me to get the contacts through him but I
can order them online for half the price which is why I haven't asked him. My
problem is trying to remember the power they were, I believe my right eye was
a -1.00 and my left I don't remember. Is there not a way of figuring it out
with the script I do have on hand?

Your eye care provider will find a lens design/brand/material that fits
properly, possibly one that's known to mask astigmatic error (if corneal) better
than other materials, place a -1.00 on each eye, wait for lens to equilibrate,
over-refract, wear trial lens for a week, evaluate, write Rx for CLs.

Hope this helps,
