(1) Do “normal” RGPs correct for astigmatism, or are there “special”
RGBs for that ?
(2) Does having astigmatism change the cost for RGPs ?
if it matters, here is my eyeglass rx:
OD -7.00 -0.75×15 (this eye has amblyopia and is useless to me)
OS -6.50 -1.50×175 (an older RX from a different doc has the cyl at 2.00)
(3) am i right in assuming that this level of astigmatism in the good eye
would require correction and that regular soft contacts just wouldnt do ?
Thanks very much

Yes and yes
It depends of the amount of astigmatism and what causes the astigmatism.
A small amount of astigmatism that correleted with the differences in the
curves off the cornea normally is corrected with a “normal” RGP lens
For higher amounts of astigmatism or situations with an (almost) sferical
(egal curved) cornea and an according prescription with a
cylinder(astigmatism) , one might use special ”toric” RGP’s
Yes, if needed the special toric lenses, you have to pay more
Regular toric softlenses might solve your problems.
