The year 1913 marks the close of the first fifty years since Abraham Lincoln issued that famous edict known as the emancipation proclamation, by which physical freedom was vouchsafed to the slaves and the descendants of slaves in this country. And it would seem entirely fit and proper that those who were either directly or indirectly benefited by that proclamation should pause long enough at this period in their national life to review the past, recount the progress made, and see, if possible, what of the future is disclosed in the past.

Excerpt: A contact lens (also known simply as a contact) is a corrective, cosmetic, or therapeutic lens usually placed on the cornea of the eye. Leonardo da Vinci is credited with describing and sketching the first ideas for contact lenses in 1508, but it was more than 300 years later before contact lenses were actually fabricated and worn on the eye. Modern soft contact lenses were invented by the Czech chemist Otto Wichterle and his assistant Drahoslav Lím, who also invented the first gel used for their production. Contact lenses usually serve the same corrective purpose as glasses, but are lightweight and virtually invisiblemany commercial lenses are tinted a faint blue to make them more visible when immersed in cleaning and storage solutions. Some cosmetic lenses are deliberately colored to alter the appearance of the eye. Some lenses now have a thin surface treatment which is a UV coating; this helps to reduce UV damage to the eye's natural lens. It has been estimated that 125 million people use contact lenses worldwide (2%), including 28 to 38 million in the United States and 13 million in Japan. The types of lenses used and prescribed vary markedly between countries, with rigid lenses accounting for over 20% of currently-prescribed lenses in Japan, the Netherlands and Germany but less than 5% in Scandinavia.

The year 1913 marks the close of the first fifty years since Abraham Lincoln issued that famous edict known as the emancipation proclamation, by which physical freedom was vouchsafed to the slaves and the descendants of slaves in this country. And it would seem entirely fit and proper that those who were either directly or indirectly benefited by that proclamation should pause long enough at this period in their national life to review the past, recount the progress made, and see, if possible, what of the future is disclosed in the past.That the colored people in the United States have made substantial progress in the general spread of intelligence among them, and in elevating the tone of their moral life; in the acquisition of property; in the development and support of business enterprises, and in the professional activities, is a matter of quite common assent by those who have been at all observant on the subject. This fact is amply shown to be true by the many universities, colleges and schools organized, supported and manned by the race, by their attractive homes and cultured home life, found now in all parts of our country; by the increasing numbers of those of the race who are successfully engaging in professional life, and by the gradual advance the race is making toward business efficiency in many varied lines of business activity.It is not so apparent, however, to the general public that along the line of inventions also the colored race has made surprising and substantial progress; and that it has followed, even if "afar off," the footsteps of the more favored race. And it is highly important, therefore, that we should make note of what the race has achieved along this line to the end that proper credit may be accorded it as having made some contribution to our national progress.Download The Colored Inventor Now!

Description

A corrective lens is a lens worn in front of the eye, mainly used to treat myopia, hyperopia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye. Intraocular lenses are surgically implanted most commonly after cataract removal, but recently for purely refractive purposes. Myopia (short sightedness) requires a divergent lens, whereas hyperopia (far sightedness) requires convergent lens.

Drawing on his own experiences and the success of the people he has treated, Liberman reveals how the fundamental self-healing properties of the body/mind connection can change the way you see the world. Liberman focuses on the intimate connection between "eyesight" and "insight" and makes it clear that changing our awareness and perceptions is the best "prescription" of all. Illustrations.
