eli5 glasses prescription purely numbers and signs

Question

I’m just a bit confused. I’ve found post about glasses perscriptions with names but I’ve just got one with purely numbers and sights l. Reads

+1.75 -2.25 x 179
+3.75 -3.00 x 173

How am I supposed to read and understand this?

Answer 1

I am not sur about the order but one is the value of the strength of the glasses, one is for the deformation of the eye and one is (I think) the inner eye pressure.
