How Sunglasses are Made

Sunglasses are an important accessory in terms of vanity, aiding visual impairment, and UV protection. Sunglasses were originally designed in a simple and fitting frame where the main purpose is to block excessive sunlight and glares. Awareness regarding the harmful effects of UV rays come into play with many of its harmful factors such as skin cancer, cataracts, and blindness as being the effects of UV. Most cheap sunglasses are often polarized and tinted without the benefit of UV protection, thus users who use these cheap sunglasses are constantly at risk of UV damage.

Sunglasses are often mass-produced in China factories before getting imported to the United States. These sunglasses are then distributed wholesale by a supplier. The materials used to create sunglasses are usually either metal or plastic frames paired with polycarbonate lenses. The polycarbonate lenses are made to block and reflect light at certain frequencies. Materials that provide UV protection can be found in certain raw materials.

Metal framed sunglasses are made with a large machine controlled by software protocols. The machine is fed with a spool of wire that bends and cuts each of the senses into a separate frame with a desired shape. Plastic sunglasses, on the other hand, are created by using mold made from raw materials.
