Switch Vision Tenaya Extreme ReviewFebruary 15, 2014
- Magnetic lens swapping system is easy to use
- Includes two lens sets and a patented magnetic LENSPOD for lens storage
- $149 package is a good value
- Relatively lightweight design
- Nosepads are not adjustable
- Lens magnets can grab unwanted objects (paper clips, etc.)
The Switch Vision Tenaya Extreme offers a unique interchangeable lens system that works well. High-energy magnets embedded into the lenses and frame keep the lenses in place but also allow for extremely easy lens swapping.
The Switch Vision Tenaya Extreme is a lightweight wrap sunglass designed with a unique magnetic interchangeable lens system that enables simple and fast lens swapping. The Tenaya package comes with two lens sets and a performance-oriented frame.
Fit & Comfort
The Tenaya Extreme from Switch Vision is a comfortable and relatively lightweight sunglass (a little heavier than other sunglasses in this test, but only by a matter of 10 to 20 grams). Gripping temples and nosepads kept this sunglass firmly in place, even during more intense activities such as mountain biking and trail running.
The nosepads on this sunglass, however, are not adjustable, which means this frame cannot be adjusted for a more custom fit. As such, I experienced slight pressure on the nose bridge when wearing the Tenaya under a bike helmet.
The Tenaya Extreme’s highly unique interchangeable lens system is what makes this frame truly worth a look. I’ve tried my fair share of lens swapping systems over time and I found the Switch Vision system to be simple, easy, and effective. No fuss, no muss.
The system works with high-energy magnets embedded into the top of the lenses and the frame top. The lenses are simple to pull out of the frame—no wrestling and jostling necessary. The ultra-strong magnets pull the lenses right back into the sweet spot when being replaced.
One downside I noticed was that the frame’s magnets also picked up desk debris like paper clips—although this could be a plus if you’d like to store your frame on your metal filing cabinet.
The Tenaya ”Glare Kit” package comes with two lens sets, including a glare-reducing polarized lens and a low-light Rose Amber lens. As a whole, this package is a solid value at $149. The polycarbonate lenses are also coated for scratch resistance, water resistance, and smudge-resistance. I experienced very little smudging during all of my lens swapping tests conducted with the Tenaya.
The Tenaya’s 8-base wrapped design effectively kept the elements out. Its lenses are also designed with a curved cutout area that encourages airflow—I experienced no fogging or other vision-hindering downsides with this sunglass.
