RE: [RC] [RC] Tevis - headlamps??? - Lif StrandAt 10:35 AM 7/11/2004, Nancy Mitts wrote:The horse's eyes seem to adjust much more rapidly than mine & they'll quickly take off again. I had always heard horses' vision adjusts more slowly than humans. According to various sources I went to online, it takes approximately 15 minutes for horses' vision to adjust when moving between differently lighted environments. It does stand to reason that if a horse's eyes are sensitive to weak light - which is why they can see practically as well at night as they can during the day - that it would be easy to temporarily blind them with artificial light at night while those pupils are fully dilated. http://www.equisearch.com/magazines/Equus/nightvision_091003/ http://www.horse-sense.org/archives/horsnigh.htm http://www.horsewyse.com.au/howhorsessee.html People must decide for themselves whether to use a flashlight or glowlights or any artificial lights on the trail after dark, but remember, when you use those lights around other people and their horses, you are making a decision *for* them, not giving them a choice, and your decision might not be what they would choose. Asking a rider to close his/her eyes while you ride by with a flashlight is not going to help their horse's night vision at all. ________________________________
