If you love sunglasses, then you should know these technical terms related to eyewear. We promise, they are not boring and you will learn something new today.
Type of Frames
Cat-eye frame: A retro style frame with up sweeps on the sides. Because of its structure, it gives the wearer a wider field of view.
Drop Temple: In this sort of a frame, the arms (or temples) are fixed at the bottom of the frame rather than the top.
Pillowed Rectangle Frames: A frame shape that is rectangular and a bit puffed or curved on the top and bottom.
Pilot-frames: A classic frame shape. Pilot frames were first seen on pilots and were later popularised by celebrities. They are known for their wide frame front and were infamous for having G15 lenses.
Retro squares: A vintage frame popular in the 50s and the 60. Retro squares were popularised by people like Andy Warhol and many others.
Readers: Glasses which are mainly used for close vision, for instance, reading.
Rimless: Eyeglasses or sunglasses in which the lenses come with no frames. They are secured by screws or nylon threads.
Semi Rimless: Eyewear with a frame on the top half of the lens, while the bottom appears to have no frame.
Shields: Large glasses. They were originally designed to fit over prescription glasses.
Tortoise: A frame that’s usually brown or gold in colour. It’s called tortoise because its design looks like a turtle's shell.
Task-Specific Eyewear: Eyewear crafted for a specific task. It can be anything for reading, to sports to driving.
Wrap-around: Frames that wrap around the head, from the front to the sides.
The various parts of an eyewear
Adjustable Nosepads: Found in the bridge area, their function is to help distribute the weight for a comfortable fit. Most pads are made of silicone because they are comfortable and stops the eyewear from slipping.
Bridge: The part of the frame that extends across the nose.
Brow Bar: A plastic or a metal piece located near the brow. This keeps the frame away from the brow to keep it from getting foggy.
Keyhole Bridge: A type of bridge that fits only on the sides and it looks like a keyhole.
Spring Hinges: Type of hinge on frames that easily moves about, making the frames more durable. It also helps in how the frame fits.
Temple: The arm that extends from the ear to the lens.
Uni-fit Bridge: A plastic or silicone that fits on a metal frame and replaces the adjustable nose pad. They are flexible and can be tailored to fit the contours of the nose.
