Golfers around the world are making the switch — and telling us they wish they’d found us sooner.
Take a moment to see what inspired us to engineer golf sunglasses that outperform everything else on the market.
How We Think About Things 🧐
The way perception works
Your eyes are just the camera - they capture light and convert it into electrical signals. But your brain is the director, editor, and interpreter that creates the visual experience you actually "see."
The same blade of grass can appear lighter or darker depending on what surrounds it. Your brain decides what color you"see" based on context and light reflecting to you. Essentially, vision is more like your brain constructing reality based on the data your eyes provide, rather than simply displaying a direct feed from your eyes!
Your brain processes visual information to execute every shot, so getting the correct visual input is the difference between success and failure on the course.
What We Take Into Account
Eye Fatigue
Don’t Be That Guy.
Eye fatigue isn’t just discomfort — it’s performance suicide.
Eye Fatigue: The Silent Game Killer
Most golfers are completely oblivious to how it’s sabotaging their performance.
The Brutal Reality:
Eye fatigue doesn’t just make you tired — it systematically degrades every visual skill your golf game depends on.
The Compounding Disaster:
As your eyes fatigue, your brain begins receiving unreliable data, forcing it to make decisions based on compromised visual input. The result is a downward spiral:
Poor visual data → Bad decisions → Missed shots → Frustration → More tension → Worse eye fatigue
The Harsh Truth:
Most golfers are playing with visually impaired decision-making and don’t even realize it. Their eyes are exhausted, their brains are processing bad data — and their scores reflect it.
Polarized vs. Non-Polarized — What You Really Need to Know
Polarized lenses reduce the amount of light that reaches your eyes, making it harder to read greens and detect subtle changes in color and contour.
Polarized Lenses Undermine Golf Performance 🙁
They should never have been introduced to golf eyewear.
In golf, your brain is constantly making micro-adjustments based on visual input. Feed it accurate, positive visuals and you’ll make better decisions — and execute better shots.
Polarized Lenses Create Depth-Perception Chaos
The Scientific Breakdown
The Binocular Vision Disruption
Polarized lenses filter light differently at varying angles, creating inconsistent visual input between your left and right eyes when viewing objects at different distances or positions.
Your brain relies on stereoscopic vision — small differences between what each eye sees — to calculate depth. Polarization disrupts this critical process.
Angular Light-Filtering Problems
As you move your head or change viewing angles during setup:
- Light transmission varies through the polarized filter.
- Visual brightness fluctuates between different viewing positions.
- Your brain receives conflicting depth cues from the same target.
- Distance estimation becomes unreliable because the input keeps changing.
Your brain operates on a trust-but-verify principle: even when technology (like range finders) gives you exact numbers, your visual system must confirm that distance before your brain fully commits to the shot.
Bottom line: Polarized lenses force your brain to make depth calculations with compromised and inconsistent visual data — a recipe for distance misjudgment.
Green-Reading Impairment
Dr. Alan Reichow, O.D., Sports Vision Specialist:
“Polarized lenses filter out the subtle light reflections that allow golfers to read grain direction on greens. This eliminates critical visual information needed for accurate putting.”
Depth-Perception Distortion
The American Optometric Association’s Sports Vision Section found that polarized lenses can create binocular vision conflicts when viewing objects at varying distances and angles — exactly what golf demands.

The KRISP™Extreme Advantage
KRISP™Extreme lenses don’t just protect your eyes with 100 % UV filtration — they upgrade your brain’s visual processing system, transforming how accurately you read the course and execute every shot.
When your brain sees clearly, your game elevates dramatically.
Technology provides the data — your eyes provide the confidence.
Real Clarity vs. “HD” Marketing
Most “HD” eyewear is just tinted film dressed up in buzzwords. KRISP™ lenses deliver real clarity — precision-cast optics engineered to enhance contrast, depth, and color accuracy without distortion.
KRISP™ lenses reveal a whole new visual experience — one that’s hard to describe until you try it. There’s a reason tens of thousands of golfers have made the switch: yes, the technology is exceptional, but more than that, wearing them is pure joy. It’s true UHD vision — with all the benefits.
Let's Compare
What Others Do
Mass Production:
Polarizing films, UV filters, anti-reflective coatings, and mirror coatings are applied by layering thin materials or laminating them onto existing lenses. These layers can delaminate over time, leading to optical distortion and reduced clarity.
Color Manipulation:
Most so-called “HD” colors are created by stacking colored films on thin lenses to manipulate how the eye perceives color — not by improving optical precision.
UV Protection:
A UV-blocking film is applied to the lens surface, often combined with a polarized layer to cut glare. The protection depends entirely on the coating — once it wears off, performance drops.
What JONDO Does
Individually Cast Lenses:
Each KRISP Extreme™ lens begins as a liquid lens material — our proprietary KRISP Extreme™ mix — poured individually into a mold for perfect uniformity. It’s then heat-cured slowly, reducing internal stress and resulting in exceptional optical clarity and consistency.
Technology — Spectral Filtration:
Instead of blocking light broadly, we manage specific wavelengths. Harmful light is filtered out, while the visible spectrum is fine-tuned to enhance contrast, depth perception, and color accuracy.
Think of it like a sound equalizer — but for light. We tune the wavelengths that matter most to your game.
Integrated UV Protection:
UV protection isn’t a coating — it’s built into the lens material itself. Our lenses inherently block 100 % of UV light, ensuring lasting protection that never fades or peels away.
Unmatched Clarity
One of the standout features of KRISP lenses is their 17% lens transmission rate. This optimal level of light filtration allows for excellent visual acuity in a variety of lighting conditions, from dim light to bright sunlight
Crisp and Clear
With a 17% transmission rate, the lenses filter out excess light without compromising your ability to see clearly. This means you can enjoy your activities without the strain that often comes with lower-quality sunglasses, no matter the light conditions
Color Coordination
Advanced Spectral Filtration selectively filters light wavelengths to create a more vibrant and saturated view of the world. It is not simple high contrast lenses, KRISP - Extreme challenges the way opticians think about light filtering, it challenges science itself
Vibrant Performance
KRISP - Extreme lenses are specifically crafted to amplify your visual experience. These lenses boost the red, green, and blue spectrums, creating a high-contrast effect that makes colors appear more vivid and vibrant
