Fun Facts About Eyeglasses
Do you know that eyeglasses has been around since the year 1260 when it first appeared in Italy? Although there is still some debate on the origin of eyeglasses, what is for certain is that they were originally designed to aid older people in reading printed materials. After its introduction, the use of reading glasses became extremely popular. In the beginning, eyeglasses designs did not have arms on them so that prescription eyeglasses and their frames were always slipping down the wearer's nose. In an effort to improve the design of these early spectacles in Spain, they tied ribbons to the frames. The ribbons were used to wrap them around the ears of the wearer. This remedy was not very effective and people did not take to wearing eyeglasses with ribbons.
Around the world, it is estimated that around 30.8 million people buy new glasses annually but very few know the history and production of eyeglasses. Some historians believe that wearing eyeglasses goes back as far as when primitive people were still reading from stone slabs. The precursor of the modern eyeglasses supposedly made its appearance in Italy in 1000 AD. This was supposedly in the same area in Italy. Between 1285 and 1289, these Italian eyeglasses were made of quartz that were set into leather bone or metal.
Other interesting facts about eyeglasses involves the human eyeball. It only weighs around an ounce and is used for a number of tasks like reading, watching television or movies, discovering, refracting light and many others. This shows how amazing the human body is. Also, sailors in the old days believe that wearing a gold earring can improve their eyesight. There is obviously no correlation between the eyes and the gold earring but the sailors may have a reason for believing in this.
An added function of eyeglasses came on the scene in 1929 when inventor Sam Foster developed the sunglasses. He was able to convince the Woolworth's store to distribute the first known brand of sunglasses, which was called FosterGrant. In the 1930's, many people were already wearing the sunglasses especially the popular film stars. It is thanks to Sam Foster that we now have eye protection from UVA and UVB rays that are also aesthetically pleasing.
At present, most lenses used for eyeglasses are made of plastics. This material replaced glass which are breakable. The process of manufacturing plastic eyeglasses means petroleum has to be used. The frames are also mostly made from plastic except for the luxury brands. Titanium and wood frames are the preferred material for the frames of the eyeglasses among the luxury brands. Eyeglasses today are also anti-scratch and anti-reflective. They are also coated to ensure that they are resistant to water. All these features require the use of some chemicals.
