For a duration this long, what your son has is most likely a vernal conjuctivitis. This is a form allergic conjuctivitis. It often run a chronic course, with potential to recur or never fully resolve.
And yes, it can be secondarily infected.
The first step is to see this for what it is, a chronic allergic condition. Identifying likely precipitants and avoiding them will go a long way in helping your son to recovery. Depending on his age, he may outgrow the condition but before then, it is important that he is seen regularly by an ophthalmologist to monitor for and prevent complications.
