Can Someone With Astigmatism Wear Normal Lenses Without Damaging Their Eyes ?

There was a similar question to this but it didn’t answer what I want to know. I want to wear costume contacts for a special event, but I don’t want to spend hundreds of dollars for one pair of custom torics. I know that torics are weighted so the lenses do not shift and you can see better with them, but are they actually shaped different from normal lenses to fit eyes with astigmatism? In this case I don’t care if the normal lenses let me see clearly. I just want to know if the shape of the normal lenses would damage my eyes. Thank you.
