If the eyes are the windows of the soul, then the glasses are the windows of the eyes-which means that glasses need to make a very good first impression. In this analogy, is your head a whole house? I'm sorry, we'll focus.

Glasses come in a variety of shapes, and the most popular glasses have won unique names and history. You may have heard of some classic glasses: pilot's glasses, cat's eyes, John Lennon's round glasses, and so on.

But how do you know if you use a cat's eye frame or a brown frame? Are all square glasses rectangular glasses by default? What are geometric glasses?

The iconic aesthetics of some glasses styles may be subtle. To help you distinguish between different shapes of glasses, we have compiled a guide to the name of the frame you should know.

Cat's eyeglasses.
Cat's eyeglasses are a microcosm of low-key charm, with a warped upper corner of the eye (closest to the temple), which seems to imply thick eyelashes. Their unique, curved eyebrows make them a feature of women's glasses style, but rest assured that anyone can wear cat's eyes, the effect is very good.

Rectangular glasses.
Rectangular glasses are the main product in the frame world for a reason: they are loved by almost everyone. The width of their lenses is greater than the height, the frames are straight and the corners are round. The shape of this kind of glasses is simple, exquisite, and reliable, but you can also add some chic to it with bold colors.

Square glasses.
The height and width of square glasses are roughly equal, and they are more angular than rectangular glasses (please say it five times quickly). The square shape can add some edges and corners to the soft and round facial features. This kind of glasses is bold in shape and has the appeal of the old school.

Round glasses.
For such a simple shape, the circle needs a certain amount of confidence to complete. Round wire glasses have an authoritative and charming retro atmosphere, while the thick acetic acid frame carries a more fashion-avant-garde spirit. It's an impressive style, but it's also a unique style that deserves respect. If you're not sure how these glasses work on you, try them at home.

Aviator Glasses
Aviator glasses are also known as pilot glasses. In their earliest incarnation, they were tinted sunglasses worn by military pilots. However, their broad lenses and bar-over-the-nose-bridge design eventually took off (pardon the pun) amidst the general public. Now they’re available as a style of regular prescription glasses as well as sunglasses.

Oval Glasses
A bit more wide than circular frames, and more rounded than rectangular ones, oval glasses have a smooth, chic look that can play well with sharper or more angular features. Their frames can be thick or wire-thin, making them an attractively flexible option for wearers.

Browline Glasses
Browline glasses, faithful to their title, have frames that outline the brows and leave the bottoms of the lenses largely rimless or with thinner outlines. They’re associated with an academic, stoic kind of style, and were hugely popular in the 1950s.

Geometric glasses.
Geometric glasses have shapes that other glasses do not have-hexagons, octagons, round-bottomed oblique tops, and so on. If the lens frame has more than four different edges, or if the shape is not easy to classify, it is likely to be a geometric frame. These glasses are suitable for people who really want to stand out from the crowd.

Oversized glasses.
Oversized glasses are not limited to a single-frame shape. As the name implies, they are remarkable because they are quite large, so they are not common in stores. However, they are not always novel-large lenses that provide a wide range of horizons, and their size makes them eye-catching accessories for fashion avant-garde.
