You probably took the Hepatitis b vaccine. This vaccine can cause vision problems that is double vision but the more serious thing is optic neuritis which also it can cause. Because of optic neuritis vision can be lost permanently. Double vision is likely to go but optic neuritis can be a serious issue. So, I would advise you to go for a dilated fundus examination as well as an orthoptic examination by seeing an ophthalmologist. Thanks.
