Facts about glasses might not sound very exciting at first but there really are some fun things to know about vision and eyeglass. With the help of the nice people over at Gordon Thomas Goodlooking Optics we have some interesting facts about glasses.
1) The first vision aid ever invented was called a reading stone, and was created around 1000 AD for the far-sighted. It was a glass sphere, and in a way, it acted somewhat like a magnifying glass. How? You would put it on top of your writing, the sphere would magnify the letters and thus help you see them!
2) Glasses made their first appearance between 1285 and 1289, and were traditionally made out of quartz set into bone, metal or leather. They were initially created to help the elderly to read, but glasses arms hadn’t been invented yet – so they would always be slipping down your nose! The Spanish tried to fix ribbons to the frames so you could wrap them around your head, but this idea proved unpopular and soon died out.
3) In numerous African countries, the cost of eyeglasses can exceed the average person’s three months’ worth of salary.
4) Over four million pairs of glasses are discarded in the USA every single year. Four million! Can you believe that?
5) However, out of all the attempts to improve vision, this has to be one of the strangest superstitions and folk remedies yet. In the past, many sailors believed that wearing gold earrings would improve your vision!
6) The first historical reference to sunglasses can be dated back to Ancient Rome and China. It was said that the notorious, bloodthirsty tyrant Emperor Nero would watch gladiator fights through polished gems.
7) Sunglasses in 12th century China (or possibly earlier) were created out of flat panes of smoky quartz, and were used by judges to hide their expressions when interrogating witnesses. After all, they do say the expression is all in the eyes…
8) The most common way for eye injuries to occur is by baseballs. The second most common is by basketball, third most common by water sports, and then fourth most common by racquet sports, such as tennis and badminton.
9) Insect eyes are often divided into multiple smaller eyes.
10) Squids have the biggest eyes in the world at approximately 18 inches in diameter. That’s roughly the size of a beach ball!
11) When they cry, babies younger than three months don’t produce tears.
12) In the first hours after a baby’s birth, they actually view the world upside down. Why? Their eyes project an inverted image onto the retina, as it takes time for the body to learn how to invert the image again so it can be viewed properly.
