Although not all eye professionals agree, some advocate exercising the muscles in the eyes the same way you exercise the other muscles in your body. Dr. Greenburg suggests these tips for women who want to keep their visual system functioning well.

Keep track. As you go about your daily life, practice tracking moving objects and following things. Computer games help with this, but take frequent breaks.

Be shifty eyed. Shift your gaze often. Fix your sights on something in one corner of the room, then the other in a rhythmic way.

Look here and there. Focus near, then focus far. When you're reading, look across the room every 2 minutes.
