With the lack of discharge making bacterial infection less likely as the cause then you are less at risk of complications from that. Also many doctors believe that minor eye infections do not actually need antibiotics.
The time of year means that allergic conditions are very common just now. The fact that you take allegra means that most allergic symptoms are kept in check but people often need eye drops on top of tablets.
So I would not worry too much. The combination of your medication does have an effect of reducing secretions in eyes, mouth and other mucous membranes so this could be making the eyes worse. Certainly using a lubricant will make them feel more comfortable.
