The bifocal reading glasses can be traced back to Ben Franklin. Ben Franklin was a busy guy. He was a writer, printer, statesman, politician, scientist and inventor. Now, according to the historical story, Mr. Franklin needed to wear two pairs of glasses, one for seeing distance and one for seeing close up. Being the active and busy guy that he was, he soon grew weary of having to exchange glasses all the time in order to see. So, he decided to cut both pairs of his glasses (called spectacles back then) and joining the two halves together, each for one lens. Now, this was a primitive way of taking care of the problem and technology has come a long way with bifocal reading glasses since then, but it got the job done. (more eyeglasses details…)

An Overview of Bifocal Reading Glasses
As the name indicates, bifocal reading glasses are glasses with two distinct optical powers. These glasses are usually prescribed for presbyopic individuals who also need a correction for myopia or astigmatism. Being popular nowadays, bifocal reading glasses can be dated back to around 1760, when the America statesman and investor Benjamin Franklin first developed them. Suffering presbyopia and nearsightedness, the great man thought it was really inconvenient to switch between two pairs of prescription glasses. Even if there are still serious historians suggesting that there were others who had preceded Franklin in the invention of bifocal reading glasses, Franklin is certainly among the first to wear bifocal glasses.

Bifocal Glasses For Presbyopia
Closely associated with natural aging, presbyopia is a health condition where the eye suffers a progressively diminished ability to focus on near objects, explained by Wikipedia. A noticeable symptom of presbyopia is that those old individuals have to hold books or newspapers at a distance farther than the normal. Only with such a distance can they get a clear view. The exact cause of presbyopia is still uncertain. Some professionals claim the research evidence supporting a loss of elasticity of the crystalline lens. Meanwhile, there is still studying evidence showing that changes in the lens’s curvature have also been discovered. In fact, all these symptoms or causes are to some extent an inevitable result of natural aging. This also explains why most presbyopic patients are over 40 years old. Without proper treatment, presbyopia can be quite bothersome in daily lives. The presbyopic may have much inconvenience while conducting even small chores on a daily basis. When the condition is advanced enough, some patients resort to a laser eye surgery. But the simplest way is to use corrective eyeglasses. Until now, there are several types of prescription glasses for presbyopia: reading glasses, bifocal glasses, trifocal glasses as well as progressive reading glasses. (more eyeglasses details…)
Bifocal Reading Glasses and Their Uses
Bifocals are not a new gift of science of recent times. It was first designed by Benjamin Franklin in order to do away with the continuous adjusting of glasses to align his vision with the shift of near and faraway objects. He designed a glass that allowed him to see the distant objects as clearly as he saw the nearer ones. Benjamin Franklin did this by simply cutting two pairs of different prescription spectacles in half and using half of each lens for each eye. Technology has advanced since then, but the basic way of making it is still the same. (more eyeglasses details…)
