Embrace your inner enigma with our Tough Nut prescription glasses. These acorn-shaped acetate frames are perfect for those with average-sized heads who wear their complexity on their sleeves (or eyes, rather). With seven sides and funky patterns, these unisex frames are every bit as intriguing and ineffable as you are. Crafted with high-tech polycarbonate lenses, our Tough Nut prescription glasses can take on anything. Their anti-reflective coating helps banish glare, ensuring clear vision in any situation. Whether you need single-vision or progressive glasses, the Tough Nut frames will redefine what it means to be "complicated."
