I've always had problems with hay fever from about May 15 to July 4. This year was no different with the grass fields in full bloom. I was figuring I'd have to curtail or eliminate my bike commuting during that month and a half; but I remembered what Jon Kline told me last year. Jon said he often rode wearing swimming goggles during allergy season. I wear glasses so swimming goggles wouldn't work; but I found a pair of chemical protection goggles at a hardware store that were big enough to wear my glasses comfortably underneath. About the second day of heavy pollen, I donned the goggles and the symptoms I was experiencing completely disappeared. I wore them through the end of June when they started cutting the grass and my eyes weren't itchy, watery nor did they burn.
Well, it isn't a great fashion statement, but it worked!
