Concentric circles, Leonardo Da Vinci, and Bausch and Lomb changed my life.
Who knew these three things – a shape, a person, and a company would converge to change my life.
Leonardo Da Vinci is credited with the idea of contact lenses, although he was interested in the mechanisms of accommodation of the eye and not in correcting eyesight.
Bausch and Lomb created the first commercially available contact lens for purchase in 1971.
And concentric circles are now the basis for bifocal contact lenses, with three circles. The inner and outer circles are used for distance, and the middle circle for reading / close up vision. My eye doctor gave me the example that when you have dirt on your windshield, you don’t see it because your eye is looking beyond it and out at the road. That’s what happens when you are looking in the distance with your contacts. And the centre part for reading is where your eye concentrates at that distance.
Today I got my first pair of these life changing, fabulous, little circles of joy. I can see far, and near, and everything in between. After a year of needing to stash reading glasses in the car, on my desk, on my nightstand, and in my purse, it almost feels like magic.
Thanks Leonardo, and Bausch and Lomb. And thanks to math, diameters, and concentric circles. My life is changed and the sun came out to kiss my cheek.
