Many issues with eye sight that result from the eyes inability to focus can be either improved or fixed with exercise. This instructable improves muscle tone in the eye but will not assist in problems caused by cataracts or other issues that block the light passing into your eye.
This is a simple exercise and is important to do if you are finding your eyes losing function when working at a computer for extended periods of time.
You will require:
something you can see that is more than 6 metres away
If you need to wear glasses to focus, wear them while doing this exercise. Your eye will do more work if it is able to get a clear focus and doing the work is what strengthens the muscles.
If your eyesight is too poor to focus on a distant object, use an object as far away as you can still focus on.
Time: 30 seconds or so. At least once per day. Preferably every hour while doing computer work.
Step 1: Finding the Right Distance.
Hold a pen in one hand so that the tip of the pen is facing up towards the ceiling.
Cover one eye with your hand and look at something level with your eye and as far away as possible. Preferably at least 6 metres.
Raise the pen in your hand until the tip of the pen blocks what you are looking at..
Focus on the very tip of the pen now.
Move the pen, still pointing up to the ceiling, closer towards your eye until it is too close to focus on.
Move it back away from your eye until it comes into focus again.
The distance the pen is from your eye now, is the distance to use for the exercise. Keep the pen in this position.
Step 2: Focus Far
Now, while you are focusing on the pen, let your focus shift to bring the far object that the tip of your pen is blocking into focus. You will notice that when you do this the tip of the pen goes out of focus.
Keep focusing on the distant object until it is clear. This should take less than a second.
As soon as it is clear, focus back on the tip of the pen again.
Step 3: Focus Close and Repeat
When you have focussed on the distant object, return your focus to the tip of the pen. Make sure you have brought the tip of the pen completely into focus and then focus again on the far object.
Repeat this process counting each time you focus far away. Do this till you count to 20.
Now cover your other eye instead and repeat the process.
Do this once an hour while working on computers or doing close work.
Once you have done this for a few weeks and seen an improvement in your eyesight, please post a comment saying how often, how many days it took and your results. This way we can all get some idea about what to hope for and maybe a little inspiration from each other.
