Perfection through Obsession.

Our Mission is to enhance your experience of the Game you Love - Helping you see the course with unparalleled clarity and Confidence

Golfers across the World are making the switch - and telling us they wish they'd found us sooner.

Take a moment and see what drove us to engineer Golf Sunglasses that outperform everything else on the market.

The way perseption 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.

Eye Fatique

Eye fatigue is a Silent Game Killer - and 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 receives increasingly unreliable data, forcing it to make decisions based on compromised visual input. This creates a downward spiral:

Poor visual data → Bad decisions → Missed shots → Frustration → More tension → Worse eye fatigue

The Harsh Truth is that most golfers are playing with visually impaired decision-making and don't even realize it. Their eyes are exhausted, their brain are getting bad data, and their scores reflect it.

Polarized lenses undermine golf performance

and 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

 Here's the scientific breakdown of why they sabotage your
distance judgment

 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 and positions. Your
brain relies on stereoscopic vision (slight 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 your golf swing 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 visual 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 and approve that distance before your brain will fully commit 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."

polarized lenses can
create binocular vision conflicts when viewing objects at
varying distances and angles - exactly what golf demands.

Krisp Extreme™ lenses don't just protect your eyes by providing 100% UV protection - 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, but your eyes provide the confidence.

What others do:

Mass production:

Polarizing films, UV filters, anti-reflective coatings, and mirror coatings are applied by adding thin layers of material or by laminating them onto existing lens surfaces. These delaminate over time and can potentially lead to optical distortion.

Color Manipulation:

Different “HD” colors are being created by colored film being layered onto the thin lenses to manipulate the visual.

UV protection:

Film is applied to thin material for UV protection. Often, polarized film is used to eliminate glare.

What JONDO does:

Individually cast lenses:

Liquid lens material (our special Krisp Extreme™mix) is individually poured into a mould, ensuring even unified distribution of the material, then heated, which allows the lens material to solidify and harden over a long period. The slower curing helps to reduce internal stresses, resulting in a lens with extreme optical clarity.

Technology:

We use the process of Spectral Filtration - While filtering harmful wavelengths, we manage visible light to enhance the colors you need in your decision-making process. We also elevate contrast and depth perception, resulting in a clearer and more vivid view. Think of it this way, just as an equalizer fine-tunes sound frequencies, we do with light wavelengths.

UV protection:

The protection is built into the lens itself, not just added as a coating or layer. Our lenses naturally filter out 100% of UV light. This means the UV protection is integrated throughout the lens material, rather than relying solely on a surface coating.
