astigmatism and soft lenses question

I am wearing glasses for 10 years and now I would like to wear soft lenses.

My eyeglass prescription is

VOD sa -1.75 = sa -0.50 dcyl ax 170 = 0.7 - 0.8
TOD dig N kPa
VOS sa -1.25 = sa -0.75 dcyl ax 0 = 0.7 - 0.8
TOS dig N kPa

Problem is that I can't find toric soft lenses with -0.50 dcyl (the smallest
is -0.75). My ophthalmologist gave me purevision soft lenses without
cylinders, but I am not satisfied, because my vision with them is not
perfect, I still have to squint while working on computer or watching TV.

I would appreciate any advice

Thank you in advance and excuse my English

=======================

there are no -0.50 cylinder toric lenses available. the smallest
cylinder correction is -0.75 as you stated.

I cannot understand for sure what your prescription is. what you
listed above has some abbreviations and added numbers that are not
used in the US (my location) and I am not familiar with (e.g. sa, 0.7
- 0.8). Please restate what your eyeglass prescription is, and what
your contact prescription is.

It is possible that your actual cylinder correction may be approx.
-0.75 or even a little more. I would be interested in seeing your
keratometry readings (corneal curvature or "K" readings). In my
practice if I had a patient who still complained of slight distance
blur I would trial them in toric lenses, and maybe some slightly
overminused powers using a lens with aspheric design.

the left eye has .75 cyl (apparently) so why not try a toric?

My location is Croatia, but I tought that that is latin.

Please restate what your eyeglass prescription is, and what
> your contact prescription is.


That is the only prescription that I have and it should be valid for both
(glasses and contacts).

I don't have keratometry readings (I don't know what is it). Should my
opthamologist measure it or?


Thank you

Yes, or toric for both. If you need -.50, then I would think that -.75
would be closer than zero.

ODs like to fit non-toric lenses, when they work. They are easier to
fit, both for the patient and the doctor. Also, some patients balk at
the cost of torics, which are several times more expensive.

Also, if these work for distance, you may be at that age where you need
different correction for close. I wore over the counter reading glasses
over my contacts for close work.

The above is based on my experience as a patient with somewhat similar
problems. Although it is a good idea to find out as much as possible
from everybody (at least that is what I think), your doctor should be
your final authority.

its OK to try torics in both or either eye. you have a small amount
of astigmatism so torics might help your acuity a little bit but not
very much. i would suspect you could readily read 20/20 with just
spherical lenses.

trying a toric lens would not hurt you in any way.
