What are Myopia Glasses?
Myopia glasses are glasses that need to be worn after nearsightedness in order to see the distance clearly. The function of myopia glasses is to correct vision, allowing for clear visibility of distant objects. In order to maintain a certain regulatory ability of the ciliary muscle of the eye. Because distant light cannot be focused on the retina, it causes unclear vision of distant objects. However, wearing myopia glasses can obtain clear images of objects, thereby correcting vision.
Glasses appeared as early as 1289 in Florence, Italy. It is said that they were invented by an optologist named Almato and an Italian named Spina who lived in Pisa. American inventor Benjamin Franklin, suffering from nearsightedness and hyperopia, invented the far and near sighted dual-purpose glasses in 1784. In 1825, British astronomer George Ellie invented glasses that could correct astigmatism. Some people believe that Chinese people invented glasses 2000 years ago. Glasses appeared in China during the mid Ming Dynasty. Ming Wanli Tian Yiheng wrote in the second volume of his "Leaving the Green Daily Gazetteer": "Every time I read an article, my eyesight becomes drowsy and I don't distinguish details. I use it to cover my eyes, my mind stays focused, and my strokes are clear. I use silk to tie it to the back of my head, and no one knows it, so I ask for it." Yu said, "This is also the name of the beginning.".
Myopic glasses are concave lenses. The image formed by a concave lens is always smaller than the upright virtual image of an object, and concave lenses are mainly used to correct myopia. Myopia is mainly caused by the deformation of the lens, which leads to premature convergence of light in front of the retina. A concave lens plays a role in diverging light, forming an upright and reduced virtual image, which lengthens the image distance and falls precisely on the retina. Far sightedness (presbyopia) is the use of convex lenses.
