Soft contacts: No, at least not on a long term basis. Sometimes your eyes shapes itself slightly to the curve of the contact, but this effect seldom lasts more than 15-30 minutes after you’ve removed them.
Rigid contact lenses: Yes, a special type of hard lens actually “shapes” your eye the same curve it has. Think “invisalign”, but for eyes instead of teeth. A doctor uses a series of contacts to remold the front of your eye over time. This isn’t permanent though and you have to wear a “retainer” contact at least once a week for the effect to stay.
Are you actually “improving” your vision though? Not really, what you’re doing is reshaping a part of your eye (the cornea) to compensate for the part that is causing the vision problem itself, which is 90% of the time an elongated or foreshortened eyeball (8% of the time the refractive error is in the cornea).
Answer:
Well, there are ortho K rigid contacts that one would wear at night that change the shape of the cornea so that during the day you have superior vision. Yes, it can be done. It is like having braces and then a retainer if you’ve your teeth worked on. Look up Orthokeratology online and see what you find out!
