GB Eyeblack was created by a professional athlete for all athletes. We're all about pro-level gear that allows you to focus on the game, not the glare.

It all started with a need: effective eyeblack without the mess.

Brad Markey started Glare Blockers Eyeblack — or GB Eyeblack — at a young age with his dad. He loved the look of eyeblack but hated the mess. They found a better solution and 12 years later, after graduating with his business degree and being drafted by the Chicago Cubs, Brad decided to bring his eyeblack design to the market. 


His teammates tested the eyeblack, helping him settle on the perfect formulation that is safe on the skin and lasts longer than the competitors. He patented the technology and GB Eyeblack was born.

GB Eyeblack was designed for champions like you – the hardworking, dedicated athletes who leave it all on the field.


Today, our mission is to equip athletes and fans with high-quality gear that enhances performance and style. We believe that every athlete deserves to focus on the game, not the glare. That's why we offer superior, long-lasting athletic eyeblack that stays put even during intense competition, eliminating the smearing and discomfort of traditional greases.


We've recently expanded our glare-reducing performance gear to include GB MAGS, the ultimate glare-blocking athletic sunglasses with three quick-switch magnetic lenses.

Whether you're a fearless football player charging through defenders, a powerful baseball hitter launching home runs, a swift softball player stealing bases or a fierce lacrosse competitor scoring goals, GB Eyeblack has got your back.
