Confused About What Type Of Contacts To Get [points To Best Answer]?

I have really bad short-sightedness (myopia) and quite bad astigmatism. I think I have to get toric lenses (that is what the optician said) because of the astigmatism but will any type work for the astigmatism AND the myopia or will they only work for the astigmatism.
I doubt I’ll get any answers so thanks if you help!

Question About How Much Astigmatism Affects Vision? Please Answer!?

I am 18 and my contacts perscription is -1.00 on the left and -1.25 on the left. For a while I have thought my vision had gotten worse because I have a hard time seeing signs on the road when I am driving especially at night and a lot of things aren’t very clear in the distance. Recently I looked at the perscription for my glasses, I don’t have any glasses but I do I have a perscription for some, and it said that I had -.5 astigmatism in each eye. Could this be what is causing my vision to be unclear? It seems like it was clearer before but I could be wrong. So do you think my vision has gotten worse or it is the astigmatism that is making me see blurry? How much would it affect it? why isn’t that correction on my contacts?Thanks
