This will certainly not be possible in this era of computers if you work with one but you can maintain them in the best shape possible by incorporating this habits:
- movement - the natural state of the eye and the body is movement, it was not designed to stay on a chair and stare at the computer all day long. The more you can get out of this state the better. - centralization - it's an exercise when focusing on specific parts of an object, diffusing and trying to see the whole object at once causes blurred vision - sketching - when switching focus from near to far objects, important for maintaining your eyesight sharp - relaxing - strain in the eye are also a cause for bad eyesight. As your eyesight goes bad you tend to squint which is causing the strain - blinking - is the most handy thing you can do when working at the computer, so do it often because it moistens your eyes and prevents dry eyes. Usually people blink 3 times less when staring at the computer - abdominal breathing - this is the correct way of breathing and not that superficial air intakes we all do - palming - it's an exercise that will literally refresh your eyes. Heat your palms by rubbing then rest them over the eyes for few minutes while you stay comfortable on your chair
