Since plastic is more cost-effective than glass, people have chosen to wear zero-lens glasses as a style statement, despite having good vision

While their exact origin is speculated, glasses today, have grown from a medically prescribed necessity to a fashion accessory. It began when those with a reading impediment discovered that looking through a certain type of glass allowed them to see better. Since then, they have become a rage among the young and old.

Glasses were invented when people made rims for ground glass and used it to read. Many from the scientific community used it to view distant objects with ease. Somewhere around the time of the invention of the telescope and the microscope, the use of convex and concave lenses began to be understood. China and Italy are the countries where people first sported corrective lenses.


Benjamin Franklin is credited with inventing the bifocal lens. He created the first bifocal lens by cutting two lenses in half and fixing them in the same frame. Later, improvements were made to this technique, and bifocals are now available in a graded lens setup. The Spanish and the Italians learned to string thread around these frames to hold them in place over the eyes. The Chinese held them in place by attaching weights to the ends. In the 18th century, Edward Scarlett, an optician, invented rigid temples that hold the lens in place on the bridge of the nose.

With progress in science, plastic lenses were invented and these have been found to be more effective than glass. They are shatterproof and can be custom-made for each eye condition. They also make for a chic look. Since plastic is more cost-effective than glass, people have chosen to wear zero-lens glasses as a style statement, despite having good vision. These are available in all kinds of frames and styles.

Sunglasses began as an eye mask, to cover the expression of the wearer. They are also used by celebrities to hide their identity or to cover up their unmade-up face. But people have come to associate dark glasses with style and coolness. They wear them, sometimes to protect their eyes against the bright sunlight, but more to appear stylish and cool.
