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.

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—for any time of day or night—in one sleek package.
Developed from original NASA optic technology, 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.

If you’re ready for 24/7 vision enhancement and protection—without compromising your prescription—order the game-changing 3in1 FitOn® System today. We’ll make sure you have everything you need to keep your lenses in top condition, including:

  • 1 x Cleaning Kit
