KRISP Extreme
Individually cast. Nothing layered on.
JONDO is the only golf sunglass provider that casts its KRISP Extreme lenses one at a time from liquid material. Spectral filtration and UV protection are in the lens — not a coating, filter, or film.
Start with liquid
The optical material is a liquid, so the lens is not cut from a mass-produced sheet and then dressed up.
Cast each lens
Every KRISP Extreme lens is cast individually. Density stays even. That is where the clarity comes from.
Lock performance in
Spectral filtration and full UV protection are part of the material. There is no surface layer to scratch, peel, or delaminate.
Why it is not polarized
Polarized lenses are useful on water. On a golf course they flatten what you need to see: the tilt of a green, the grain, the ball leaving the clubface.
KRISP Extreme stays non-polarized and manages light inside the lens instead. Contrast comes up. Depth stays honest. Eyes work less hard over 18 holes.
Light transmission is tuned near 17% — bright enough to read a green, calm enough for a full round in sun.
Against coatings and films
| Coated / film | Polarized | KRISP Extreme | |
|---|---|---|---|
| How it is made | Stamped, then coated | Film or filter added | Cast one lens at a time from liquid |
| Clarity | Depends on the coating staying put | Often clear, visually flat | Even material. Nothing on the surface to fail |
| Depth on greens | Unchanged, until the coating wears | Reduced. Breaks look flatter | Preserved. Non-polarized on purpose |
| Ball flight | Contrast fades as the layer scratches | Can mute the ball against the sky | Spectral filtration tuned for course contrast |
| UV | A surface treatment | Usually a coating | Integrated into the lens material |
| After a season | Haze, peel, delamination | Same film problems, plus flat depth | No coating to scratch off |
