Palming is so simple, most people have a hard time believing that it actually works. Yet it is, I believe, one of the most powerful eye exercises there is! Here's what you do: Place your palm on your eyes to block out all light from reaching your eyes then imagine anything that relaxes you. When you're relaxed, your eyes are relaxed and when that happens, you take away the strain that causing the deterioration!
Place two items, about 40 cm, away from each other. Position your head in the middle of them, at a height where you normally would read a book. Slightly turn your head to face the left item. Try to see the item without seeing the other. This trains your eyes to focus and the ability to focus properly is crucial to perfect vision.This last one is not exactly an eye exercise but it's so crucial I have the urge to include it here. If you ever hope to improve your eyesight naturally... then you have to stop wearing your glasses! If you can't see, then at least get a weaker one. You have to allow your eyes to adapt and re-learn how to see clearly without lenses in front of them.
The invention of contact lenses was such a revolutionary progress in the field of ophthalmic, which is no less than a miracle. Previously, there were immensible problems in this field, which were difficult to manage. It was such a top-level development in correcting refractive problems, which were not only extremely complicated but also too expensive, and majority of people were unable to afford it. As it came in the market, not even a single one who preferred glasses after using these lenses.
In this way, there are few abuses, which were also developed because people began to use lenses without knowing the facts, uses and abuses of lenses. Here it should be noted that old contact lenses need more care, hygiene and they are much more toxic to human eyes. By keeping these abuses of old lenses, manufacturers of lenses began to make lenses, which are less toxic to human eyes, and by which there are less chances to get allergic and they also need less care and hygiene.
You can find several different varieties of lenses made by different companies and come up with different brand names are easily available in the market. You will find either hard or soft lenses when you will go to buy lenses. You should know pre-hand that hard lenses are made up for specific uses and indications. In soft lenses, you can find extended wear, which are worn after some time and need constant cleansing and you need to replace them after some time.
