|Though prescription glasses are used universally and has a long history behind them, there are certain little – known facts about them. There are quite a few of them, and knowledge of them actually making your eye-wear experience more fun.
When reading glasses first appeared in Italy it was more than 700 years ago. Though they became quite popular in a very short time, they didn’t use to have arms, which made them slipping from the nose. The Spanish tried using ribbons which didn’t found many takers. For example, sailors used to believe that it is better to wear gold earrings than prescription glasses to improve vision.
In recent history, sunglasses came on the scene in 1929 with the young inventor Sam Foster somehow convinced the Woolworth’s store on the Atlantic City Boardwalk to sell his brand – FosterGrant. When it caught the attention of the movie stars it became an immediate sensation, within a year. No one, including Sam Foster, thought that blocking UV rays can become a fashion statement! Now-a-days, prescription sunglassesare also available with numerous designer brands.
One of the most unknown facts is that from birth, we are accustomed in seeing a blurry world around us. But since, that’s the only kind of vision we have, we accept it as normal. Once we start wearing the prescription glasses, we get a clearer vision. After months of use, when we remove them, we again see a blurry world, but we believe that this is not normal vision and thus, get the idea that our vision has worsened. It is also perfectly natural, that once one starts aging and reach the age of 40 years, they may start suffering from presbyopia. This disorder occurs to every individual and it has nothing to do with whether the individual is wearing or not wearing prescription glasses.
Similarly, using your eyes for any length of time does not make them weaker. One may get tired or even get a headache but these symptoms don’t mean that the eyes are getting weaker. Even sitting close to the television is not harmful to the eyes, especially since the modern TVs have stopped emitting harmful radiation. One must remember that eyes are just the receiver of lights. The actual analysis is done by the brain. When one gets tired or have a headache, it generally means that the brain is overworked and not the eyes.
