Beating the Blues

Is blue light messing with your golf game?

Beating the Blues

By Deanna Pai

So you’ve been practicing, but what if the thing that’s holding back your game isn’t your grip or alignment, but your eyesight? That could be the case thanks to a phenomenon called blue light. The good news? Cutting-edge technology can help counteract it. Learn how blue light might be messing with your golf game – and what you can do about it.

Blue light is everywhere. It’s one of three colors on the visible light spectrum (along with red and green), a high-frequency, short-wavelength light that scatters. As a result, most people tend to see blue light as glare, either from the sun or bouncing off a reflection (such as a freshly polished midiron, or a pond in the middle of a golf course).

When blue light enters your field of vision, something called veiled glare occurs: the blue bounces around within your eyes, causing stress and resulting in short-term issues like burning, itchiness, and fatigue. In the long-term, this type of photo-stress can affect the back of the eye – namely, the retina and the macula. Blue light can even be damaging.

Battling the Blue Light

Blue light scatters so much that it can even reflect off an object in motion – like a golf ball. “On a sunny day, that results in motion blur,” explains Todd Trifaux, an independent vision industry consultant who works with Sundog Eyewear. It can throw off your game, not to mention tire out your eyes.

Enter TrueBlue lenses. The patented technology was designed to counteract the harmful effects of blue light by taking cues from the body’s natural sources of blue-light protection. “Our body produces melanin, which is in the back of the eye and protects the eye from blue light, and ocular lens pigment, a pigment at the lens of the eye,” says Trifaux. Both of these pigments are injected into TrueBlue lenses during manufacturing, helping them absorb blue light rather than simply reflecting it.

Get Rid of the Glare

By reducing the amount of glare around you, you can better focus on both your aim and the ball. Think of it as the visual equivalent of making everyone around you stop yelling as you tee up. Since how clearly and accurately you can see directly impacts your shot, protecting your eyes with TrueBlue technology can make that eagle a real possibility (versus, OK, kind of a pipe dream).

TrueBlue technology comes in a few tints. The rose-gold tint, like that of the Rea TrueBlue sunglasses, allows you to better see changes in the contours of the green. The brown tint of the Razor TrueBlue Lens boosts contrast, helping those who have trouble making out the shadows on the fairway. Meanwhile, “on a bright, sunny Florida day, a gray tint is more soothing,” says Trifaux. Try the Ellwood 52 TrueBlue Polarized if you’re getting your game on somewhere with less shade. Pick whichever sounds like your weak spot.
