Finally, there’s a way to protect and enhance your vision 24/7—from UV rays to blue light emissions to low-light or nighttime conditions—and wear your prescription glasses.

Here’s how it works: The 3in1 system begins with a strong but lightweight foundation—stylish, full frame crafted with durable TR-90. The base frame is equipped with our exclusive DigiTec® technology. These clear, micro-infused lenses block blue light emissions from smartphones, tablets, computers, and TVs. Less blue light means less eyestrain and fatigue—and more comfortable (and longer) screen time.

And it gets better. The 3in1 FitOn System includes two lightweight clips that magnetically (and effortlessly) attach to your DigiTec® base frame. That means three different types of vision enhancement and protection in one sleek package.

The dark amber of our TriLenium® polarized lenses block 99.9% of harmful UVA and UVB rays, combat side light and glare and amplify colors and clarity. Whether you’re at the beach, playing a round of golf, or just enjoying the sunshine, snap on these lenses for optimal vision protection.

When the sun goes down, switch to your exclusive Night-Lite® lenses. Designed for optimal clarity and definition in low-light conditions, these yellow, micro-infused lenses also block glare, making them perfect for evening games or shows, night driving or walking the dog around the neighborhood after dark.

So, if you’re ready for 24/7 vision enhancement and protection—without compromising your prescription—order the game-changing 3in1 FitOn® System today.

Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

Switching from computer work to driving without changing glasses has been seamless—the blue light filtering is a game-changer for my late-night screen sessions. The full frame design feels sturdy and blocks side glare surprisingly well.

Carter P. ★★★★★

I’ve been wearing these all day—through harsh office lighting and an evening walk—and the blue light filtering makes a real difference when I’m staring at screens. The transition from indoor to low light is smooth, so I don’t have to swap glasses constantly.

Aurora ★★★★★

The full-frame fit actually covers my whole field of view, no annoying gaps at the edges like my old clip-ons. I keep them in the car and wear them day to night, and the blue light filter genuinely helps on long drives.
