If it weren’t for gravity, we’d all be floating around getting nothing done. Worse there would be no oceans or rivers or lakes. The water wouldn’t stay still. Gravity makes things fall to the ground at a rate of 9.8 meters per second squared. That means the more they fall the faster they fall.
Sir Isaac Newton formulated his theory about gravity. He didn’t discover it. You can’t discover something that just is. That’s like saying the first man discovered Life. You live, that's life.
The problem with gravity however is that it makes things fall that you don’t want to fall. Like if you’re in a rush in the morning, you might spill orange juice on your white dress shirt.
Or if it’s a winter’s day and it’s iced out on the walkway, gravity will make you fall. And then most likely you’ll be stuck in bed for a week nursing a bad hip or worse.
And for eyeglass wearers, gravity is the worst because it makes your eyeglasses keep slipping down your nose.
Glasses sit on your head with nothing to keep them from slipping. They’re made of metal or plastic which in themselves are slippery. They sit on your head slanting slightly downwards because your ears and higher than the point on your nose where the eyeglass nosepads make contact. Pointing downwards is a recipe for eyeglass slipping.
And of course the center of gravity on your glasses is near the front because your lenses are there. Your lenses are heavier than the rest of your glasses. Center of gravity is what gravity works on.
So that’s why your glasses slip.
But they don’t have.
When you put your jacket on a hook, how come it doesn’t fall?
Of course because the hook keeps your jacket from falling. That’s what Keepons eyeglasses retainers do. They’re engineered from special silicone that’s ideal for this type of work. They thread over your eyeglass temple tips and hook over your ears so your glasses never slip down your nose.
