1.50 standard single vision or 1.57 mid-index single vision?

Hey guys, I just got my new prescription. I want to order cheap glasses online, but I do not know what lens I should get. There is standard single, mid-index single… I really don't know.

My prescription:
OD -150 x -0.50 x 005
OS -2.25 x sph

Since this question has been asked before, I'd prefer if someone named a site where you can plug in your prescription and find the best lens for you.

Bonus question: Why did my doc write "sph" in the cyl? Does that mean that only my right eye has the astigmatism?
