Cat-eye sunglasses often have a round frame and oval lenses. They have different ornamental, appliqué, and sculptural effects on the top edges. This is ideal for someone who likes the retro style.


The Oval frame is wider with rounded edges. It is designed for people with a square or diamond face.


These have a broad frame and are wider resembling the oval sunglasses. Their sharp-edged rectangle frames give a bold statement look and a softer look around the edges.


These are designed with a 50’s style; they have a vintage and timeless sense. They have no frames in the bottom part for a semi-rimless look.


Octagonal frames are designed with eight-sided lenses, hence the name. They give you an angular style.


These do not have a rim wrap around the frame, meaning they weigh less than other types.  With these, you can see more since nothing is obstructing your view. They give you a unified look by bringing more attention to your face and eyes.
