Persistent red eye with a foreign-body sensation and hazy vision after a week is not normal and needs urgent re-evaluation, as it could be due to worsening infection or inflammation like Keratitis or severe Conjunctivitis. Medicines like Duobrom and L Pred should not be continued without review, especially steroid drops. Please see an eye specialist immediately, avoid rubbing the eye, and do not self-medicate further, as proper examination is essential to prevent complications.
