Eye doctors recommend that you do an eye crunch because when you’re actively using your eye muscles, you’re reducing your chances of myopia (nearsightedness) and eyestrain, which especially occurs among those who spend hours working in front of the computer or watching television. Dr. William Bates, an ophthalmologist, developed the earliest eye exercises in 1900 and he authored the book Perfect Sight Without Glass in 1920. Other benefits of doing an eye crunch include blood circulation to the eyes, reduction of eye tension and a reduction in the risk of age-related macular degeneration. Finally, the eye crunch repairs a lazy eye, which occurs when some of your eye muscles weaken.
One eye crunch to try is to read from an eye chart that you can purchase from a medical supplies store. Paste the eye chart on a wall that’s a few inches away from you then glance up at it every few minutes. Another idea is to put your hand over one of your eyes then try to read some of the letters on the chart. Do the same eye crunch with your other eye and repeat this for a few weeks.
