I'm not sure why that means you should "hate" a particular brand. F55 torics
are about as stable and predictable as other brands. They also come in two
shapes, and you didn't say which.

It helps to deal with vision and comfort as two separate issues. I gather
the right eye *felt* ok, but the vision varied.

Not necessarily a step upwards. Torics are tricky and America's Best usually
caters to price shoppers.

Believe it or not, those two prescriptions are very similar. Notice in each
case the first number goes down but the second number goes up. Those changes
offset each other and if you figure the spherical equivalent (a standard
measurement of overall strength) you find each eye stayed exactly the same.
Also notice that the third number (axis) was identical in the left eye and
only changed by 5/180 in the right.

You'd probably be happy with glasses made from either pair. They probably
represent accurate measurements at different ends of normal diurnal
variation.

As I said, it isn't a big change. And astigmatism doesn't typically change
much. But readings vary by +/-025 on the same day with the same examiner, so
a variance of 050 over three months is no surprise. And one meridian got 025
steeper and the other got 025 flatter; that's typical of the variation you'd
see in an individual.

Probably the biggest variable is examiner instructions and the patient's own
sensitivity to cylindrical blur.

Other causes for variation are dehydration eg antihistamines, exposure,
climate etc., as well as hormonal skin changes, sleep, and lots of others.

But yours didn't change much.

With toric contacts ( and glasses) it's usually preferable to undercorrect
astigmatism than to overcorrect it. So if you were making glasses, use the
first prescription. If *your* contacts are made the same strength as your
glasses, something is wrong.

NO toric will stay in place 100% of the time. If it does it's too tight. So
instead of looking for the "right" contacts, try to find the least annoying
of them. With your prescription, it's unreasonable to expect torics to be as
sharp as glasses.

If you want perfection, you should check into gas perm contacts. Sometimes
they work out better than glasses but we'd need to know more about you.

Just got my frequency 55 soft toric trial contacts after two weeks. Again,
they are Frequency 55's, which I really hate. I wore contacts several years
ago, and it took several tries to "get it right."

I haven't worn them for about 4 years. I went to Eyeland and my prescription
was:

Right Eye: -4.25 x -3.25 x 020
Left Eye:  -4.50  x -2.75 x 155

I got those trial contacts and they were bad. The left eye felt good but the
right eye didn't seem to fit right and had frequent blurriness. I wasn't
happy with Eyeland so I went to America's Best about three months later.

My prescription was:

Right Eye: -4.00 -3.75 x 025
Left Eye: -4.25 -3.25 x 155

So, which prescription is right? Why the change after just 3 months? After
two weeks I got my trial contacts and at first they seem better than
Eyeland's first attempt. The right eye seemed a bit clearer and feels better
in my eye. But... after awhile stills get blurry and out of focus far too
often especially at longer ranges. No matter who fits my contacts, it feels
like the right eye is always messed up, as if there's a blurry film over my
vision. The left eye doesn't feel as sharp as it did with Eyeland's trial
pair, but again, better than my right eye which causes the problem. Also, as
with the other contacts, even with two eyes, if i'm seeing clearly it's just
a matter of time before everything gets blurry for a second or two before I
have to blink many times to clear it up. what's the problem? are they not
staying in place? what can they adjust if my prescription is correct? is
there another brand other than frequency 55 that i can use?

i have to schedule another appointment for the doctor to check my vision and
make an adjustment. i'm sick of this.
