Quality and Technology
 “I’ve never seen a problem that can’t be solved when you’re working 14 hour days.”
 — Randolph Engineering founder, Jan Waszkiewicz, commenting on quality control

Sportsman SunglassesOverall Quality and Frame Technology
Randolph Engineering products are famed for their quality and durability. Each pair of our sunglasses goes through more than 200 production stages – mostly by hand. We even make our own solder flux. As a result, our frames provide unequaled strength and solder joint integrity.

In our drive for superior quality, we scour the world for the best components and special alloys – with tight molecular structure to eliminate rusting and oxidation. We do not compromise quality even when selecting something as trivial as a lens screw. Our nose pads are made of soft silicone to prevent the frames from slipping, even during heavy perspiration. While fashion may fade in and out of the marketplace, the quality found in Randolph Engineering products will never go out of style.

We feel so strongly about the quality of our products that we will repair or replace any broken solder joint for the lifetime of the frame (assuming normal use). That is one of the many reasons we call ourselves “serious equipment”.

Lens Technology – Sunglass Series
Whether you’re piloting an F18 fighter jet or driving a car, you need the best lenses available to protect your eyes and enhance your vision. When it comes to superior quality lenses, Randolph Engineering has you covered. All of our lenses absorb 98-100% of harmful ultraviolet rays and allow a range of 12-18% of visible light to pass through; the ideal comfort level for most wearers. Our mineral glass lenses are exceptionally scratch-resistant, and will provide you with absolute distortion-free clarity. They’re also precision ground and chemically tempered for impact resistance that exceeds ANSI Z-803 standards.

Lens Technology – Series
From any shooting discipline to fishing and hunting, quality lenses will not only protect your eyes from numerous hazards, they’ll actually elevate your performance and prevent your eyes from becoming fatigued. Those who are serious about the quality of their vision depend on Ranger lenses to perform, no matter the goal. Although all Ranger lenses absorb 100% of UV rays and are molded at above industry standard thickness for your protection, the best advantages to wearing our lenses are enhanced definition and optical clarity. Unlike other shooting lenses, Rangers are made with distortion-free optical-grade polycarbonate. This gives you the level of protection you need while not compromising the quality of your vision.
