How to cure a crossed eye, lazy eye, ect?

Crossed eye: This condition is some type of strabismus, and in a young child should be evaluated urgently by an ophthalmologist--an eye surgeon/md. Sometimes glasses, and sometimes glasses with patching of the better eye may do the trick. Other times eye muscle surgery is needed. There are some types of strabismus that are harder to correct. If it is for you, seek out an adult strabismologist specialist.
