Sports science has monetised the marginal gain — altitude tents, beetroot shots, and a smear of eye black to absorb stray glare.
Commit fully. If two black stripes cut glare by a fraction, a complete matte-black face abolishes it, along with several other perceptual inputs. Our performance lab reports zero glare events across the trial, a 12% drop in passes received, and a referee who asked the player to identify themselves twice. The stripes, it turns out, were load-bearing.
