After the discovery of the contact lens, decades have passed; the modern versions of the contact lens are used at large extents among the people all over the world. The discovery of contact lens lies deep past in history at the end of the 19th century. The lens discovered at that time was not used because those lenses were nothing but large pieces of glass. Later, with the advancement of technology, the construction materials of the contact lenses changed; lenses are now made of plastic related materials, which make the contact lenses light, soft and almost invisible. Unlike the lenses made of thick glass, these lenses are used extensively all over the world. Most people nowadays, use these lenses instead of the thick glassed heavy eye glasses. Before the discovery of the modern contact lenses, the glass spectacles were the only tool for the protection of the eyes. When the use of lenses started at large rate, people found out that they were much better in many ways than the glass spectacles. So they discarded the eye glasses and shifted to the contact lenses.
But, if we observe properly, we can see that the lenses are not advantageous over the eye glasses in all respects; there are certain things in which the lenses lag behind the contacts. As for the maintenance and usage of the lens; it is a little difficult to insert and remove a lens and its maintenance costs a lot of time. The lenses need to be cleaned and disinfected daily using the solution provided with the lens. But, if a person uses a glass spectacle, he or she does not have to face such difficulties. Wearing or removing a glass spectacle from the eyes does not need any practice or time, neither does it has to be cleaned or disinfected with any solution. Cleaning a glass spectacle with a clean piece of cloth is enough to keep it clean. Even the glass specs cost much less than some contact lenses like the permanent lenses or the colored or themed contacts. Besides these, the contacts lens is better than the eye glasses in all other aspects. Contacts can be used by practically anyone and people wearing a contact lens do not feel uncomfortable or irritated like that of the glass spectacles.
Because of the huge advantages of the contact lenses, millions of people have discarded the glass specs to use the lenses. If you are a spectacle user and want to shift to a contact lens, then do not waste time. Consult an eye-specialist as soon as possible and get a contact lens that he prescribes from any medical store or from any online store. There are few things people should keep in mind while buying a contact lens; firstly, do not go for the cheap contact lenses from any ordinary manufacturer; these lenses may not be suitable for your eyes and can even harm your eyes. Always get lenses from the world famous lens manufacturers and look for the solution provided with the lens. This solution is very important for the maintenance of a lens.
