    All this while I've been ordering astigmatism contact lenses..and the stats on the box are:
    Bc: 8.6
    Sph:-6.00
    Cyl:-2.25
    Ax: 170

    And these are bausch and lomb 59s..

    But recently, the site I've been buying from have stopped selling the 59s because of thr suppliers. So I'm looking at air optix lenses for astigmatism?

    But their lenses only come in 8.70 base curve. What's the difference here?

    Between 8 5 and 8.7? Is it a big difference?
    Oh. And the reason whh I buy them online is because my friend owns an optometry shop and told me where I can order minus the service charge and etc.

    That being said..if there is a big difference, I'll just go to a shop
