Do you believe that the earliest prescription glasses were made of glass tube with water, these are not even special lenses, story has recorded such eyeglasses over two thousand years ago, so, you can see, today’s variety of prescription glasses are results of time, all of us have the right to wear eyeglasses, while, at that time, only the authority have the power to wear them!
It was not until 13th century that the first pair of prescription eyeglasses, which have glass lenses, have emerged in Italy. But who is the inventor, no one knows, someone believe it was a monk, while others insist some scientist, this question is still controversial. However, we pay more attention to their functions not the inventors, as we need them for correcting our vision problem! Nowadays, those prescription eyeglasses are widely used, and they are spread to all places of the world, eyeglasses are available by any group of people, young and old, men and women, some people just need to wear a pair of eyeglasses frame to change their appearance!
As we know, old day’s prescription glasses can only be used to correct inferior eye problems, and you may don’t know that the earliest eyeglasses are invented for rectify hyperopia (presbyopia), and those Rx glasses for myopia are emerged much later. People know the principle of the convex and concave prescription eyeglasses lenses until the 17th century. You may familiar with today’s bifocal and progressive eyeglasses, yep, that they can be used to treat both with nearsightedness and presbyopia, but who invented them, it was said Franklin, who is one of the most important scientist in the history of the United States of America.
Great changes have taken place in prescription glasses since the first pair of eye wears have emerged, we have plastic, metal, stainless steel and even titanium eyeglasses frames, as the lenses, we come from the old days glass to plastic material, such as CR-39 and PC lenses, in particular, the appearance of contact lenses is a important progress, some people even doubted contacts would replace ordinary prescription eyeglasses as in some senses, contacts are do better than eyeglasses, however, prescription glasses can always maintain their popularity. So, why? Why such eye wears are still popular? In my opinion, that’s because of the ideal of design firmly related with fashion. Nowadays, eyeglasses are both for function and fashion, and they have some relationship with self-interest. Wearers are seemed very nice and attractive with those prescription glasses!
