Acetate Material
Acetate—or, more specifically, cellulose acetate—is the caviar of plastics. It’s durable, hypoallergenic, and capable of holding exceptionally rich colors, which makes it an ideal material for eyeglasses and sunglasses.
Anti-reflective coating
All Colossein sunglasses lenses are coated with high-quality super-hydrophobic treatment. This step is especially important for those who work with computers—and it also keeps your glasses looking so fresh ‘n so clean-clean.
Cat-eye Style Frames
Cat-eye frames are a shape of frame that swoop upwards, like…um…cats' eyes. (You saw that coming.)
A woman named Altina Schinasi Miranda is credited with inventing the first cat-eye-like shape in the 1930s. Miranda was a window display designer in Manhattan who thought most glasses were hideous and unsuitable for fashionable ladies. Inspired by harlequin masks she’d seen in Venice, Miranda got creative and designed a pair of glasses that mimicked the masks. (She snipped the first prototypes out of paper). Fast-forward a few years and the new style of glasses is suddenly in vogue AND in Vogue. Marilyn Monroe wore them, Nina Simone wore them, Brigitte Bardot wore them…all the cool girls. Now we call them cat-eye frames. You can wear them even if you’re more of a dog person. It’s allowed.
Fit
Do your frames fit? Here’s how to tell.
Mixed Material
Some mixed things are bad (like mixed messages). Some mixed things are good (like mixed nuts). Our Mixed Material frames definitely belong to the second category. These frames include densely-hued acetate and metal flourishes.
Nose bridge
“Nose bridge” refers to the slope of the nose in between your eyes. (Put your finger there. It’s a nice little area, isn’t it? Definitely an underrated body part.) A low nose bridge is where the bridge of your nose sits level with or below your pupils. People with low nose bridges often have wide faces and/or high cheekbones. (Tip: Low Bridge Fit frames minimize any pinching and prevent frames from sliding down your nose or resting on your cheeks. Which is fantastic, because no one on earth wants to be pinched by a pair of glasses.)
Nose pads
Twin pads that rest on the sides of your nose and ensure a snug fit.
Polycarbonate
Polycarbonate is an über tough transparent plastic with exceptional impact resistance. (It won’t break if you drop it, unlike eggs, crystal vases, fine china, water balloons, etc.). some of standard Colossein sunglasses and all optical lenses are fashioned from polycarbonate.
Polarized lenses
Polarized lenses eliminate glare, making it easier for you to see without straining your eyes. How do they work? Physics, punk! Light waves vibrate in different directions, and most of the light waves that cause “glare”—those shiny reflections off a pool or a highway—are horizontal. Polarized sunglasses have teensy vertical filters that prevent horizontal light waves from entering. Voilà: no glare. It’s so simple, yet so cool.
Readers
Readers (or reading glasses) are glasses with non-prescription lenses that make it easier to read (or do anything that requires really good eyesight at close range). They’re available in various preset magnification strengths, which users can choose from to match their needs.
Temple
Also known as the arm, this is the part of your glasses that runs alongside your head and holds them in place.
Titanium
Titanium is a strong, durable substance that holds up well under force. (Just like you.) We use it to make glasses because it has a high strength-to-weight ratio, which makes it ideal for an item that rests on your nose. Also: Titanium never rusts.
Its symbol is Ti, like the rapper.
Titanium was discovered in 1791. Other fun things that occurred in 1791: Vermont became a state, the guy who invented Morse code was born, and the world’s first Sunday newspaper was published. Yeah, it was a good year.
Tortoise shell
In the 19th century, tortoise shell was a prized material for all sorts of household objects, from combs to cigar boxes to spoons to paper cutters. Fancy people stored champagne in tortoise shell ice buckets. It made sense: Tortoise shell is a beautiful material, with complex marbled hues and a rich glow. Even the ancient Egyptians used it.
The problem is that tortoise shell originally came from an actual animal; specifically, the hawksbill sea turtle. This big guy grows to three feet long, has a cute little beak, and enjoys swimming among coral reefs and lagoons. In 1973 the Endangered Species Act was passed, which officially protected hawksbill sea turtles from being hunted. They’re still endangered though.
Here’s where it is important to note that our tortoise shell is NOT made from actual tortoises. We would never do that. Instead, ours is made of custom cellulose acetate. Our designers have a lot of fun concocting tortoise hues of every shade—with no cruelty involved.
Yes!
This is what you will shout—possibly accompanied by a fist pump—when you put on your first pair of Colossein sunglasses and glasses. Good times.

When we see a pair of glasses, we tend to think that the simple structure isn’t too complicated to be made. However, just one pair of glasses, from design to production, goes through hundreds of procedures, eventually becoming the elegant masterpiece lying on the bridge of our noses.
Today,
we wanted to introduce
how the original glasses are made.
We are going to skip over the preliminary designing procedures, and mainly introduce the manufacturing procedures of the production processes.
① Plastic Frame
Cutting Ring Materials
Cut the ring material directly into a square. Using the template as a reference, make the cut 4 mm wider, and length 8 mm longer. The bending stake curves the rings, and lengthens it by 6mm.
Plastic Dryer
Put the cut materials into the oven and let dry for 72 hours, furnace temperature controlled at 62-65 degrees Celsius. The cut materials before processing will be shrunk with infrared rays. This is to prevent shrinkage at a later stage.
The Inner Ring, Outer Ring, and Frame Design
The inner ring, outer ring, and frame designs are completed at once by CNC (Computer Numerical Control) and is sent for handcraft.
Restructuring of Ring Materials
After going through rough rolling and mid-rolling, the ring frame material is entered into a small oven to soften, making it easy for restructuring. It must be noted that it cannot be put in the oven for too long, otherwise it would blister.
② Glue
Inserting Pin and Removing Extra Glue
After the pins are put in place, use a cutter blade to remove the glue overflowing on both sides of the hinge by hand, and be very careful not to leave marks on the hinge.
Extra Materials
The glue and eyeglass temples need to be assembled and processed according to their structure or size, and then extra materials are thrown away.
Structuring the Tail
The eyeglass tail is bent at an angle where the curvature and length are based on the drawing requirements.
Levigation
When glue is set with pins, you need to polish with a waterstone to ensure that the surface is smooth without protuberance.
③ Assembly
Peg Hinges
Peg the metal hinge into the front ring. Remember that the hinge can be electroplated but not glued.
Assembly
Align the hinge screws and assemble the front frame with the glue.
Polishing
When the eyeglass frames come out of the roller and assembled, scratches will be naturally made, some parts even with hard spots. Polishing can get rid of these scratches and hard spots, and to the greatest extent boost its shine.
④ Packaging
Lens Cutting
When cutting polaroid and presbyopia lenses, in addition to matching the spectacles to the frame, the parameters also need to be checked if the requirements are correct. As for the plain lenses, it only needs to be matched to the frame.
Labeling
Printed labeling needs to be clear, complete, neat and shouldn’t easily come off.
With the above complex manufacturing processes, can you see why the manufacturers of eyeglasses can be named "craftsmen", and their finished eyeglasses can be treated as works of art?😎
