You would most likely be prescribed glasses that have a strong astigmastism for your left eye and if your right eye is amazing like you say then the right side of your lenses wouldn't have a prescription. The type of glasses would just be ordinary ones, you could even use contact lenses to help your situation. Definitely check up with your optician about this and if you decide to try contact lenses they should provide the help you need to start using them and teach you.
Hope this helps,
