I am afraid you might have had some injury
to the superficial layers of the cornea
due to some ill-fitting contact lenses. You are advised to not use contact lenses till the problem subsides completely and 3 weeks beyond that. Instead you can use glasses for a better vision.
It is better if you get yourself examined by an eye specialist for a proper examination of your cornea. Meanwhile, you can use some lubricating eye drops 3-4 times a day and some anti-biotic ointment at bed time.
