Sometimes when you’ve been around for a while on here, you forget how steep the learning curve can be. I did not know these things when starting, either. But please, understand that it is exhausting to answer the same basic question a hundred times when you could easily google that. Or search the blog, or youtube, or the wiki. You can find the answer literally everywhere.
For your question, sphere is the lens strength for your myopia/near-sightedness. Cylinder is the strength for your astigmatism, and the axis is about where on the lens it is corrected for.

Or watch Gemily’s nice summary: https://www.youtube.com/watch?v=cAyobmi1AvQ
And I would strongly encourage you to go through the wiki and the youtube videos (Jake’s of course, but the very practical videos of other students as well). People on this forum are very nice and sometimes take the time to answer basic questions (God knows I’ve asked a few of them myself), but that is out of generosity, as there should be some prerequisites to the discussions on here. Just the basics. Everyone is allowed to make mistakes, but not to be too lazy.
