eye infection

I am 58 years old, having a very bad eye infection for 3 weeks, after my children and grandchildren all had flu last month.Is my eye infection relating to this flu? I receive medications for 3 weeks but nothing helps. in the begining I had also weakness in my body but no fever.

The eye specialist said that it can be adnovirus. Another specialist that I saw yesterday said tht 3 weeks is too much for a virus , so he thinks that it's not. I would like to know your opinion.
