The eyes are chalk full of tiny muscles. The muscles main job is to change the shape of the eyes. The actual eyes change shape so they can focus and move up, down, and side to side. As with any muscle in your body, without proper exercise and instruction the muscles can weaken as we age. Most people are forced in to artificial lenses because the muscle tissue are too weak to change the shape of the eyes.
The lens from the eye hardens with age forcing the muscles to work tougher. The eye muscles can be educated to work no matter how hard the lens get. It is the muscles around the eye that control the shape of the eyeballs. Once you learn how to exercise and train these muscles it is easy to put them to good use and avoid the need to actually need glasses.
Almost all eye problems are due to mental stress and excess stress on the actual eyes. Learning how to relax the eye and also the eye muscles is the best factor to ensure you will never need synthetic lenses. Relaxing your eyes sounds difficult, but it is much easier compared to you think. We cause the eyes unneeded strain by taking a look at things that annoy or irritate us. Take some time out to concentrate your sights on enjoyable things. Put photographs around or on the desk at work of things that bring joy as well as happiness. Look at these photos when you are feeling especially discouraged or stress and concentrate upon relaxing and calming down.
Practice relaxation the eyes at night while lying in bed. In the darkness, close your eyes and cover them with a sheet or blanket. Let your mind think about pleasant things such as people, places, or things that bring you joy. Thinking pleasant ideas helps relax the eyes which make them softer. The softer the eyes are the more easily they fit into their sockets. When the eyes are relaxed, they don't stare or strain.
Practice relaxation techniques until they become more organic. Take the time during the work day to relax the eyes for at least 10-15 minutes. You will find you're more energized and can concentrate more clearly on your work.
