How have lenses been used to change the world?
Lenses have played an instrumental role in the advancement of society. In this article, we will highlight three select examples, but we encourage you to look more into it if the topic intrigues you.
To start things off, let’s draw attention to something a little close to home. I’m talking about corrective lenses. I’m sure some of the people reading this have them, and they can tell you it’d be difficult to read this otherwise. Corrective lenses come in many forms. This can include contact lenses, glasses, and a lens which can be surgically implanted, which is called an intraocular lens. Lenses have improved the vision of those who would otherwise not see, and for that we thank them.
Have you ever just stared out into the sky and just wondered? Well, The Netherlands came through when a couple of 17th century men named Hans Lippershey, Zacharias Janssen and Jacob Metius of Alkmaar invented the refracting telescope. Galileo Galilei improved upon the design soon after. When man first gazed upon the extraterrestrial canvas of space, the desire to explore and understand it overwhelmed him. We thought that Earth was the center of everything, the world was flat, and the sun rotated around us. Upon the advent of telescopes, we found ourselves gazing upon the stars as those before us, but there now existed a clarity unheard of previously which allowed us to dispel our previous misconceptions and again fueled our desire to reach beyond the cradle of humanity, Earth.
This is an article I am writing. I've still got one more paragraph to write, and I'm probably going to use cameras, but if anyone has a better idea for lenses, I'd appreciate it. Also, I'm posting this for opinions.
