I have never heard of using sunglasses to block pollen but it probably does help!

Very helpful. Thanks!

One tip that wasn't mentioned is increasing water intake: "You can naturally prevent asthma and allergy by drinking more water. When you understand the physiology of the human body and the role of histamine in its water regulation and drought management, you realize that chronic dehydration in a vast majority of people is the primary cause of allergies and asthma. Increased water intake—on a forced, regular basis—should be adopted as a preventive meas­ure as well as the treatment of choice." (from http://campaignfortruth.com/Eclub/190609/CTM-Allergies.html)

Here's another great contributing piece that discusses the role of water in "curing" allergies: http://voices.yahoo.com/water-cure-allergies-asthma-colitis-fatigue-headaches-53020.html?cat=5
