The high impact, lexan dual tint sunglasses from Zurich were the lightest and most useful sunglasses any of us have used on any previous expedition. They blocked all UV rays at altitudes over 20,000 feet and consistently keep the wind out of our eyes. The wrap around design are a must for any climbing situation. The peripheral vision associate with this unique design is excellent and prevent eyestrain due to UV or bright reflected light from entering around the edges of the glasses.

Our Sherpas thought that these were the best glasses that they have used or worn. They especially liked the stylish colors and shapes. We would recommend these products to any serious outdoor enthusiasts who require the ultimate in UV protection, as well as stylish good looks!

I found the Zurich sunglasses protected against harmful sunlight rays as well as my own pair of glacier glasses, or any other type of glacier eyewear I have worn. Although I had no way of measuring percentage of the lenses' filtering capability, I noticed no eye discomfort at any time. The Zurich glasses fit and remained in position on the face well. There were no high winds during the climb to see if high winds effected their fit. I did notice some discomfort after wearing the Zurich glasses for an extended period of time (approximately 6 hours or more), where the ends of the temple pieces pressed against the boney area behind the ears. Other types of glacier glasses use a separate earpiece, made of a softer material than the temple piece, which wraps around the ear to hold the glasses in place, and eliminates pressure on the area behind the ear. This may not be noticed by others wearing the Zurich sunglasses; it may just be the way they happened to fit me.
