today i learned – weds 12th apr 2017

with our holiday now drawing to an end, today is most definitely a day for enjoying the sun for one last time before jumping on a plane and being greeted at home by everyone’s best pal – the cold 😒.

grabbing my custom made emoji sunglasses  for one final time (i’m not posh … i just stickerbombed some shades and now they’re sick 😎) i couldn’t help but wonder: “who was the clever soul who invented sunglasses?”. a quick search later, i’m now smarter than i was 😏.

#tdil that modern sunglasses have had a long ole ride that started way back in china in the 12th century 😱.

originally, sunglasses were invented for the super rich people of china. as you can imagine, they were quite different to the ray bans that you have on your face these days – in fact, they didn’t even protect your eyes from the sun all that well. made from a slab of smoked quartz that was crudely fitted into a rough frame, all they actually did was slightly block out the blaring sun 👍🏻.

but wait, there’s more! they also had a use within the law system … i know right, the law system?! judges in china started using these new fangled sunglasses during trials to help hide their emotions. 

…during the following centuries, people started to experiment with adding tinted lenses to vision-correcting glasses 👍🏻. it’s not massively interesting and tbh that’s the gist of it … so we’ll skip the indepth dive 😬.

modern sunglasses started appearing in the 20th century because hollywood celebs began wearing them to protect their eyes from the bright studio lights. they were then made mainstream in 1929 after a dude named ‘sam foster’ started mass producing them –  he did very very well out of this business 💰💰💰. it’s worth mentioning that these sunglasses still didn’t protect your eyes from the sun’s uv rays (more on this later).

in the 1930s, the army air corps started to use specially created sunglasses to help protect their pilots from high altitude glare 😵 (<- that’s the face you pull when the sun gets in your eyes at high altitude). they actually ended up perfecting a special dark green colour that absorbed light from the yellow band of the spectrum. 

right, back to the uv swag – in 1936, edwin h. land founded the polaroid corporation after inventing the polaroid filter that protected people’s eyes from dangerous uv rays. these were totes desired by everyone because they were both fashionable and better for your health #winwin.

and finally, in 1936, ray ban started creating aviator glasses with new polarised lens technology (created by edwin) for ww2 pilots. they later made these aviators available to the public. ray bans were founded by an american company called “bausch & lomb” – the same company that created those army air corps sunglasses from earlier in the post 😬.

there you have the history of sunglasses 👍🏻.  if you’d like anymore interesting facts about sunglasses, my source can be found –>here<– 🙂. the ray ban information came from the place on the internet that knows all: wikipedia 😂 … if you’d like more on that, you’ll find it –>here<–.

anyway, time for some final sun ☀️☀️

aloha 🙃 #tdil
