How Lenses Work?

It is quite interesting to note how lenses work. These plastic like membranes correct several refractive errors while resting on the surface of the cornea. They function much like spectacles but provide more precise vision as compared to them. They aim at refracting and focusing light in the right way so that objects could be seen easily. The reason for precise vision is that they stick to the eye and remain there with the help of fluid contained within eye. This means they would move naturally along the cornea. The only requirement for maintaining lenses is cleanliness. Proper cleaning routine is required to make sure that the contact lens last longer and provide the highest level of vision. Unhygienic, over-worn and dirty lenses can cause severe eye infections and could affect the vision as well
