Negative Cylinder with Acuvue Advance For Astigmatism With Hydraclear

I was looking at Acuvue Advance For Astigmatism on the Internet and it looks like these only come with negative numbers in the "sphere" section. Why is that?

Acuvue Advance for astigmatism offers up to -9.0 and up to +6.0 sphere for their lenses.. which is power correction.

Perhaps you were looking at the cylinder figure for correcting the astigmatism which goes up to -2.25.

Hope this clarifies it for you

I checked this out on a couple of sites and I think Miss Kitty is right, Bessie. I think you meant that all the cylinder values were negative, which is what you put in your title. I think you probably typed "sphere" when you meant "cylinder," right?

As for why the cylinder values were negative, I really can't help you with that. Sorry.

You're right. I meant "cylinder." Sorry.
