You take the time to exercise your body””and even your mind. But what about your eyes?
Healthy eyes depend on proper nutrition, proper care and””yes, proper exercise! Over time, eye muscles may become weak and rigid, causing blurred vision and other problems. A number of factors affect eye muscle weakness including the use of corrective glasses or contact lenses, and aging.
Special optical exercises can help strengthen and train eye muscles, supporting your ability to focus and helping your eyes to maintain a healthy shape. Pinhole glasses are one way to exercise your eyes.
Pinhole glasses look like sunglasses, but with grids of tiny holes on each lens. They work like this: the holes allow only narrow beams of light to enter the eyes, increasing the wearer’s depth of field vision and reducing the retina’s blur circle. For people with refractive errors (meaning the shape of the eye doesn’t bend light correctly), the result is sometimes a clearer image.
Pinhole glasses have been around since the 1950s. They’re safe and can be used by both near- and far-sighted people. Although there’s no scientific evidence to support permanent improved vision, pinhole glasses may be beneficial for some individuals. If you try them, remember that they reduce peripheral vision and should be used while standing still or sitting down.
