stop glasses from sliding down nose for good
Your left ear. Your right ear. The left side of your nose. The right side of your nose.
The four places where your eyeglasses make contact with your head.
In the case of your left and right ear, you skin makes contacts with plastic temple tips.
In the case of your nose, it makes contact with your eyeglass nosepads though with some plastic frames, there’s no nosepad per se and then your nose just makes contact with the frame.
Some people like to think of those four points of contact like wheels on asphalt. I used to think that, but lately I’ve been studying the problem so more and now I tend to think of it like a baby carriage on an ice rink.
That’s it. This is reality.
And it always amazes me why people think glasses shouldn’t slip down their noses?
What’s to keep it from slipping?
Your skin makes contact with plastic. Your skin has pores. When you’re active, those pores release moisture called sweat. The sweat makes contact with plastic. Wet plastic. Slippery.
And so every little movement causes the entire framework of your eyeglass frames to slide forward. Then gravity does the rest. Because ain’t it just like gravity to pull down?
Or maybe some people think that glasses come with some type of anti-gravity device which makes them defy gravity and for those people whose glasses are slipping, that somehow this anti-gravity device is malfunctioning…
The reality is that glasses slip down your nose because their slippery and nothing is stopping them from being slippery.
Think about it, if your ears were made of felt or some other wispy fabric and the temple tips of your eyeglasses were made of Velcro then definitely they wouldn’t slip right?
But that’s not the case.
Your skin is epidermal layers which is smooth. That’s why you glide through the water when you swim. And when you sweat those epidermal layers get moist and the moisture makes the glass temple tips and nose pads slippery and then your hands automatically come up to your face. Another slipping glasses push up. Except you don’t use your ab muscles, you use your arm muscles.
So like I was saying…glasses slip because they’re designed to slip. Or rather no one ever designed not to slip.
Until now that is.
Keepons eyeglass retainers.
What’s a retainer? It’s a device which holds something in place. Keepons holds you glasses in place, that is, squarely on your head.
Keepons are two swatches of silicone shaped like small boomerangs. Through one arm of the boomerang runs a hollow tunnel which your eyeglass temple tips thread through. Once thread through, the other boomerang arm goes around your ears comfortably, like a soft hook.
The hook stops the forward movement of your glasses.
No more slipping glasses.
And that’s the science behind Keepons eyewear retainers.
Magical, but no magic involved. Just Physics and common sense.
