Sunglasses and Headaches
Most people suffer from headaches at one time or another, and many people in North American suffer from migraines, ranging in frequency from several times a year to once a month or more often. In many cases, a migraine or severe headache forces the sufferer into isolation until it goes away, damaging their ability to work, socialize, and generally live life to its fullest. What most people donít already realize is that many migraines and headaches can be prevented through the regular use of a good set of sunglasses! Regardless of whether itís the summer solstice or the frigid depths of winter, a high quality pair of sunglasses is a very useful preventive health item as well as a fashion accessory. Since bright light can trigger migraines, headaches, and contribute to tension and other disorders, a good pair of sunglasses can significantly improve your quality of life, as well as preventing serious eye degeneration that can eventually lead to blindness. An effective pair of sunglasses should block both UVA and UVB rays, but new research suggests that High Energy Visible (HEV) light may also contribute to eye disorders, particularly in children. There is still insufficient data on this subject, but some manufacturers now design to block UV rays as well as HEV light, reducing your changes or visual damage from light sources.
Itís very important to note that dark glasses are not the same as UV-exclusive glasses. Check to make sure that your shades are made by a reputable manufacturer, and that theyíre certified to block out UVA and UVB at least - if they donít do this, itís very possible that theyíre worsening your exposure to harmful light by tricking your eyes into. Since damage from UV exposure is cumulative, itís important to regularly wear a high-quality set of sunglasses, and to start young. If you teach your children at a young age about the value of wearing good sunglasses, you may save their eyes from damage later Ė and besides, everyone knows how cool a good set of shades look.
