"Review: 32°N Muir Adaptive Focus Sunglasses with Liquid Lenses"

32°N's Muir sunglasses by Deep Optics feature liquid crystal lenses that can change focus with a swipe, serving as both sunglasses and reading glasses. Priced at $849, the glasses offer convenience for those needing both types of eyewear, but the limited magnification area and slight delay in focusing may take some getting used to. While the technology is impressive, the high cost may make potential buyers hesitant, but the company offers a 30-day money-back guarantee for those interested in trying them out.
