Monocat is a stylish pair of glasses designed for individuals who require more than one pair. It features interchangeable, differently colored eyepieces, allowing users to match their mood or outfit. The eyepieces can also be swapped for different filters or transformed from dioptric to solar lenses using neodymium magnets. The magnets secure the eyepieces while keeping the lens center, which houses the diopters, in place. Monocat draws inspiration from the classic monocle design and incorporates elements of contemporary "Cat Eye" morphology.
