Once you put on a pair of sunglasses, you have here a touch of the instant mood: coolness, protection, mystery, or style. But have you ever thought how complex a road that couple of shades made to the surface of your face? There is an elaborate world of design, engineering and accuracy behind all classic aviator and fashionable cat-eye glasses. The work of a contemporary sunglasses manufacturer is much more advanced than making plastic and glass mould.
The Foundation: Design and Engineering
The procedure commences way before any material is cut. One of the most famous sunglasses manufacturers engages in design massively with the priorities of artistic imagination and ergonomics. The design team researches facial patterns, the latest trend in fashion, and the ancient masterpieces to make the frames that look beautiful and comfortable to wear. Meanwhile, engineers are trying to figure out the technical specs: the hinge mechanism that enables thousands of opens, thousands of closes, the optimum amount of curvature to the frame so the lenses will not pop out, and the exact position of the nose pad to ensure maximum comfort.
The Art of Lens Crafting
A sun glasses lens is the backbone of the glasses. Here is where a trusted brand of sunglasses will be able to stand out among the low-end imitations. It is not a matter of tinting only. Good lenses begin with a material foundation, such as polycarbonate as an impact-resistance material, or glass as an optical-clarity material. These are then coated several times to various effects: UV protection to block out harmful rays, polarized filters to help eliminate blinding glare and anti-reflective coating on the back of the lens to keep light bouncing out of the eyes.
Precision in Production: Assembly and Quality Control
Assembling starts with parts in place. This is the phase of machine dancing and human handwork. Plastic frames are made by injection molding machines, acetate sheets are cut into layered, colorful patterns by CNC machines. In the case of metal frames, the parts are welded, polished and plated. Final assembly-lenses into frames, hinges and temple arms- are frequently done by trained technicians and make sure that all the parts are exactly aligned.
Next there is the most important step, quality control. Both are carefully checked on the slightest defect–a slight scratch on a lens, a slight bend in the hinges, an imperfection in the coating. A high end sunglasses company has a zero-tolerance policy on defects, and that only flawless products are delivered to the consumer.
The Final Product: More Than an Accessory
The process of raw material to a finished product is a marvel of the modern manufacturing world and the desire to excel. Next time you wear your favorite pair of sunglasses, remember that you are not wearing mere accessories. You have a slice of carefully chosen science, design innovation and quality craftsmanship- all the signs of a passionate sunglasses manufacturer who is devoted to keeping your eyes safe and making you look good.
