The eyes are chalk full of tiny muscles. The muscles main job is to change the shape of the eyes. The eyes change shape so they can focus and move up, down, and side to side. As with any muscle in the body, without proper exercise and training the muscles can weaken as we age. Most people are forced into artificial lenses because the muscles are too weak to change the shape of the eyes.
The lens of the eye hardens with age forcing the muscles to work harder. The eye muscles can be trained 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 ever need glasses.
Almost all eye problems are due to mental strain and excess stress on the eyes. Learning how to relax the eye and the eye muscles is the best thing to ensure you will never need artificial lenses. Relaxing your eyes sounds difficult, but it is much easier than you think. We cause our eyes unneeded strain by looking at things that annoy or irritate us. Take some time out to focus your sights on pleasant things. Put photographs on or around the desk at work of things that bring joy and happiness. Look at these pictures when you are feeling especially frustrated or stress and concentrate on 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 thoughts 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 natural. Take the time during the work day to relax the eyes for at least 10-15 minutes. You will find you are more energized and can focus more clearly on your work.
