UV protection technology is becoming increasingly more present in many products, for example many foundations, lip balms and car windows. However, like sunglasses, their use is very specific, i.e. lip balm only serves to protect the lips, and foundation for the skin, thus minimising the competition surrounding sunglasses as they are specifically for the eyes. https://www.51lunwen.org/ArtandDesign/ Most niche products that have a very specific purpose don't have a very large range of consumers, however, sunglasses resist this trend as they have proved to be immensely popular despite their small use, due to the 'moral panic'[10] regarding health issues concerning the damage UV rays can do to your sight .

Consequently, there is limited competition as sunglasses seem to have monopolised the market for products that block the sun from individuals' eyes. However, a minority of people dislike wearing sunglasses and therefore substitute them with goods such as baseball caps, sun hats and visors. In sports, for example tennis, certain sunglasses are designed in order "to ensure that the ball is clearly visible... And to ensure that your eyes are offered the best possible protection" (Tennis Sunglasses, n.d.) [11]. Yet, certain players, especially professionals, don't wear sunglasses due to the disadvantage of limited vision, and therefore a cap is preferred.

However, other sportswear designers have made exciting new variations of sunglasses to fit their particular interests and needs. For example, water eyewear has been invented for players of sports such as surfing and wakeboarding, and are designed to be "Robust, have wind protection and reduce fogging" (Extreme Sports, n.d.)[12]. Another area where sunglasses are developing scientifically is the aerospace sector. Because there is no protective atmosphere, leading to more harmful solar rays, "titanium alloy frames than can withstand extreme conditions of space travel" (NASA, 2002)[13] are used, along with gold lenses inserted into the many layers.

Celebrities and the media are a major influence on the fashion aspect and popularity of sunglasses, as they have so much power over the public's perception of the zeitgeist at any one time. Their main appeal today is as a fashion accessory, and there is a lot of competition between companies to get their product to become the sunglasses to own. After the 1960's, when many advertising campaigns were coined, the industry exploded into main stream shops and into the media, where"only a few decades earlier none existed" (Ament, 2006)[14], and the public found the appeal of wearing sunglasses, regardless of the intense sunlight本论文由英语论文网整理提供

A successful implication of the market surrounding sunglasses is the potential for complementary goods. Many products have been created purely as an accessory to the sunglasses, as getting a product that everybody with sunglasses needs will consequently do very well. An example of this is Sunglasses Cases. This creates another niche market which will do very well, as people will need to own something to keep their product safe. A second good that is interlinked with the purchase of sunglasses, albeit not as successfully, is Lens Care Kits. However, the majority of consumers will be swayed to buy products if they can identify it with something they already own.本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
