Salves and ointment may not help that best for conjunctivitis .The entire treatment must be in order and regular.A healthy diet following the natural criteria and a thorough cleansing system can help you to avoid conjunctivitis.As said in the earlier posts fresh fruit diet can prevent you a lots of diseases and this is also applicable to conjunctivitis.And the fresh fruit diet should include Apple,Pears Orange,Grapes and Pineapple,Juices are welcome.Try his fruit diets for seven days and another important thing is that Bananas should not be taken,The fruit diet should only include fresh Juicy fruits.The procedure is that you should take the juice of the desired fruit in a glass of warm water every two hours from 8(Morning) to 8(Evening),and no other stuffs should be in taken(In order to get the fruit diet to its perfection)

.Orange juice is very much preferable,Carrot juice is also welcome if you have a problem with orange.This juicy fruit diet should be followed for seven days as said and after these seven days you should change your diet a little.
After Seven Days
For Breakfast you can have any fruits except bananas.For lunch Mixed Raw Vegetable salad with bread or butter and Chappatti.For dinner Steamed vegetable along with fresh fruit and nuts(Potato must be discarded).
Personally I also advise natural ways to treat pink eye or conjunctivitis. Especially the food mentioned here is spot on and very useful
For more topical treatments I suggest:
Hot compresses (if the eyes are crusted in the morning) or warm tea bags are also helpful
Also fennel compresses and charcoal poltices have produced good results
You could also rinse with a saline solution (artificial tears) or cabbage juice
Honey solved in water uses it’s anti bacterial power against bacterial pink eye
