I use prescription "Patanol" prescribed by my allergist along with my other routine allergy medication. The allergist described it as liquid gold and it has helped immensly.

Benedryl is good, but it may not be strong enough. Have you tried Claritin or Claritin-D? It may help you better. Having natural tear eye drops or gel will also allow you to wash away the pollen and minimize eye irritation resulting form contact.
