Renewing your driver's license soon, and wish to be sure to pass the vision test and put off the need for eye glasses for another 5 or so years? When you've verified with your doctor(s) that such exercises are ok for you to practice, and then at your own volition, Start these exercises in an attempt to better vision:
There appear to be some notions about doing certain eye exercises, to which a claim is laid that may improve one's vision.
Certainly not an expert in the field, I have been trying them, and couldn't really tell you for sure that it has helped me by leaps and bounds, but that they may have helped to some degree, in my over-all vision.
These 'exercises' were brought to public knowlege, at least in part by a person named Bates, about a hundred years ago.
What kind of eye exercises ? How are they done?
One of these, which I've come across, in several places on the web, and, in a text book or two, some time ago, goes like this:
Roll your eyes
Look as far as you can, to the right, then to the left, up, down. That simple exercies stretches certain muscles, which if I'm not mistaken, help with convergence, or the function of focusing both eyes onto a point (which certainly funtion when your looking straight ahead, focuisng on something, not off to one side). Just take some time, every day, and roll your eyes as wide as they will roll, in both directions. Keep your eyes wide open and move your eyes in large circles to the left and then to the right, looking as far to the 'edge' as possible. Avoid the inclination to move your head while doing this. Only when doing this, let your office colleagues know what you're doing ahead of time. You don't want them to catch you off-guard doing this exercise. They may get the wrong idea and think "Wow, what kind of rush is this freakazoid on?"
Keep your eyes fixed on the tip of a sharpened pencil
Hold a pencil with the tip end pointed up, and touch the pen to your nose. Some people may experience dizziness when trying this for the first time, so be seated when you try this. Focus as hard as you can on the ball point, while slowly moving the pen away from your nose to arm's length, all the while focusing, and then return the pen, just as slowly, back to your nose. Repeat this exercise, again, for a few minutes, each day, and see if you don't notice an improvement.
Focus near and far
Keep in mind that whatever you do to consciously exercise your eyes, can only help, unless you over-do it. These exercises should never be painful. With a precision-finished item (a cylindrical rod standing on end, for example), place it between you and a far wall. Position the cylindrical rod at about eye-level. On the far wall, place something with considerable detail (maybe an eye chart?). The cylinder and the chart on the far wall should be inline from where your standing. Focus first on the cylinder, making sure to focus 'hard' on the corners, and then refocus on the chart, on the distant wall. You'll notice that when you're focusing on the cylinder, the chart in the background will become 'double' and blurred (or it 'should' anyway), and vice versa. This will help with how fast you can focus between near and far.
"Sunning your eyes"
Sunning your eyes, basically is closing your eyes while looking at the sun. Don't do this if it's painful. If it is painful, look away, to a point where it's not painful to "look" at the sun with your eyes closed. The sun through your eyelids, it's claimed, is supposed to nourish the eyes in one way or another. I do it, and though I don't have Superman's vision, I think it does me good.
I read somewhere on the web, that the normal, healthy set of eyes is the set that is constantly moving. Don't get into the habit of just staring at something, especially while driving. Police Officers are trained to keep their eyes moving, scanning from one side of the street to the other while driving. With just a little practice and discipline, this will become a healthy habit for you. (I believe so, anyway, and it's what I do).
