THE FUNDAMENTAL PRINCIPLE
Do you read imperfectly? Can you observe then that when you look at the first word, or the first letter, of a sentence you do not see best where you are looking; that you see other words, or other letters, just as well as or better than the one you are looking at? Do you observe also that the harder you try to see the worse you see?
Now close your eyes and rest them, remembering some color, like black or white, that you can remember per fectly. Keep them closed until they feel rested, or until the feeling of strain has been completely relieved. Now open them and look at the first word or letter of a sen tence for a fraction of a second. If you have been able to relax, partially or completely, you will have a flash of improved or clear vision, and the area seen best will be smaller.
After opening the eyes for this fraction of a second, close them again quickly, still remembering the color, and keep them closed until they again feel rested. Then again open them for a fraction of a second. Continue this alternate resting of the eyes and flashing of the letters for a time, and you may soon find that you can keep your eyes open longer than a fraction of a second without losing the improved vision.
If your trouble is with distant instead of near vision, use the same method with distant letters.
In this way you can demonstrate for yourself the fun damental principle of the cure of imperfect sight by treat ment without glasses.
If you fail, ask someone with perfect sight to help you.
