Yoga of perfect sight

Almost every eye specialist of the world believes that for refractive errors there is not only no cure but partially no preventive also. From such a belief any rational mind will conclude that science is in a very imperfect stage. What some writers on Ophthalmology wrote two hundred years back about the incurability of the refractive ailments, is continuing as a dogma even today, in the days of advanced science. We are so much hypnotized by the assertions of the old authorities that we do not are to make any experiment or do some research on the subject. And if anyone comes forward to say that cases of errors of refraction can be improved without glasses, we begin to doubt and without any study discard his explanation. Such is the condition of our mind which is supposed to be scientific. A scientific mind is always open to admitting a truth or a fact.
