The cat-eye lift on a rectangular frame is a small detail that changes everything. The shape stays structured and grounded with all the clean lines you'd expect from a rectangle. But the upward sweep at the outer edges adds a lightness that makes the whole thing feel more alive. In thick black acetate, that energy is held in check just enough to feel subtle rather than dramatic. Yellow-tinted lenses are a genuinely useful choice for everyday wear, especially in changing light conditions.
