Please answer me.
Thanks for your Question
Red eye doesn't necessary mean an infected eye. There are many causes of red eye such as infection, allergic conjunctivitis,subconjunctival Hemorrhage, corneal wound, high intraocular pressure or Glaucoma, anterior uveitis and many other causes.
The best way to treat his condition is to know the cause and to do such thing he should visit and eye doctor for complete eye examination.
