You know, it's funny.

We don't often think of eyewear as performance gear until it starts to get in the way.

And if you're like me, somebody who has contended with eyesight impairment my entire life,

it's a very real thing without a real solution for athletes.

I cannot tell you how many times I've been

mid-run, constantly shoving my glasses back up my nose, tripping on roots and rocks because

I couldn't see them or my glasses had fogged up or what about out on the bike where the treachery

is obviously far more intense. Well, this is why Roca has been

a godsend for me, approaching prescription eyewear from a performance perspective first, but not at the

cost of fashion, I should say, helping not only people like me, but all kinds of athletes, including

Georgia France cyclists and Iron Man champions with everyday frames designed for movement.

Their secret is their proprietary gecko technology, patented nose and temple pads that grip even more

securely when you sweat. No slipping, no distractions. And they're insanely lightweight. Most

frames weigh less than a pencil, super light,

even with prescription lenses. Beyond the function, the craftsmanship is next level,

razor sharp optics, durable construction, and a design that actually is beautiful and keeps up

with you. So put them on, feel the difference, and wear without limits. Unlock 20% off your order

is this big brain on the top of our bodies, but it doesn't come with a user's manual.

It can consume up to 25% of the body's energy, so just imagine the amount of work that it does.

The nervous system is responsible for sensation, perception, feelings, thoughts, and behaviors.
