My Rx is in the -7 range, with astigmatism in the -1 range. My previous
toric contacts over the past couple years were Frequency 55 (for one eye)
and Soflens 66 (for the other), but both lenses rotated out of place
frequently and I wasn't real pleased with them.

My new optometrist just tried a couple different Biomedic toric lenses on
me, but those seem to rotate a lot too.

Now he's ordered me PureVision Toric lenses to try, which he says are
stiffer and hopefully less likely to rotate out of place. I haven't gotten
them yet, but was wondering what opinions you eye docs have of these lenses,
since they are pretty new. Are they less likely to rotate than Biomedics and
similar lenses and do they tend to work well for hard-to-fit patients?

Also, how does a lens' water content affect tear levels in theeye? Do the
ones with higher water content tend to absorb the tears more like a sponge,
and make the eye feel dryer? Or does it work the opposite, where all the
water in the lens keeps the eye moist?

It looks like PureVision lenses have less water content than the previous
ones, but from what I understand, in silicone hydrogels, the silicone is
what transfers the oxygen rather than the water in regular hydrogels, is
that right?

Any and all opinions on PureVision toric lenses would be appreciated!
