Why black is the cat eye's colour
A cat eye works by line. The frame's top edge rises from the bridge to the outer corner, and the eye follows it; the steeper and clearer the line, the more lift the face gets. Black gives the clearest line of any colour, because it contrasts with every skin tone and does not break up the way a tortoise or a crystal does. It also hides the frame's thickness, so a black cat eye can be bold without looking heavy. The cat eye sunglasses guide covers the shape in every colour; the black sunglasses guide covers the colour in every shape; this piece is the meeting point.
Gloss or matte
Gloss black is the classic: polished acetate that catches light along the top edge, which sharpens the lift and reads as dressed. It suits evening, a wedding, anything where the pair is part of the outfit; the wedding sunglasses guide is the occasion piece. Matte black absorbs light, so the line is softer and the frame reads as more casual and more modern; it suits daytime, denim, the beach. Most black cat eyes in acetate are gloss, and most of the MUJOSH pairs below are polished acetate; the metal one is the exception and sits between the two.
How much lift
The cat eye runs from a corner that barely rises to one that points at the temple, and the amount of lift decides who the pair suits. Soft lift (the corner rises a little): the everyday version, flattering on almost every face, and the one to buy if you have never worn a cat eye. Medium lift: the fifties shape, clearly a cat eye, still wearable all day. Sharp lift: the corner rises past the brow line, the most striking version and the one that photographs best, but a pair for occasions on most faces. In black, each step reads a step bolder than in any other colour, so choose one notch softer than you think.
How much size
Small and narrow. The nineties and two thousands cat eye, a frame that sits inside the face; it suits small faces and anyone who wants the shape without the coverage. The small sunglasses guide and the sunglasses for small faces guide cover the fit.
Medium. The classic size: the lens frames the eye and the frame ends at the temple.
Oversized. The lens covers the brow and reaches the cheek, and the shape turns into the butterfly, the cat eye's big sister; the butterfly sunglasses guide and the oversized sunglasses guide cover that end. In black, an oversized cat eye is the boldest thing in this range and the most flattering on a round or oval face.
Which face suits a black cat eye
Round faces take the most lift and a medium or oversized size, because the rising corner adds the angle the face lacks; the sunglasses for round face guide says more. Oval faces take any version. Square faces take a soft lift and a rounded lower edge, so the frame does not repeat the jaw; the sunglasses for square face guide covers the rest. Heart faces take a narrow frame with a soft lift, because a wide black top line on a wide brow over a narrow chin tips the proportions; the sunglasses for heart shaped face guide goes further. The how to choose sunglasses for your face shape guide covers all of them.
The lens to pair with it
A black frame takes any lens, which is the other reason to buy the shape in black. Grey is the match: a neutral lens that keeps the frame as the whole statement, and the one most of the pairs below carry. Polarized grey adds the glare filter for water and roads, and the polarized cat eye sunglasses guide ranks those pairs on their own. Dark grey on a black frame is the full fifties look; the dark sunglasses guide covers when a very dark lens is right. A coloured lens on a black frame, burgundy or rose, is the way to add colour without losing the line.
Fit: the cat eye's one weak point
A cat eye carries its weight at the outer corners, so if the bridge does not sit on the nose, the frame tips forward and the lifted corners drop, which undoes the whole point of the shape. People with a lower nose bridge see this most, because most frames perch on them instead of resting; a frame cut for a lower nose bridge, with the bridge lower and closer to the face, keeps the corners up. Many of our frames are cut that way, every pair below among them, and the low bridge fit sunglasses collection gathers them. The how should sunglasses fit guide gives the four checks.
