All sunglass manufacturers are now required to label all sunglasses appropriately to inform the consumer how much UV and sun glare protection their eyewear will provide. These categories are rated on the amount of harmful UV radiation and also the amount of visible sunlight that the lenses absorb. These sunglasses are categorised as follows;

CATEGORY 2 = Sunglasses for general use that provide good protection from visible light and from UV rays.  This lens will have a tint which allows through less light than category 1 but more light than category 3.  A graduated tint will be categorized as 2.  A graduated tint is a tint which is dark at the top of the lens and gradually gets clearer towards the bottom of the lens.

Inspired by the fresh and unpretentious style of New York's urban youth, Calvin Klein set out to launch his own clothing company in 1968. With financial backing from his childhood friend Barry Schwartz, he commissioned a local seamstress to make a handful of coats and dresses. A merchandise manager from Bonwit Teller visited Klein's dingy showroom by accident and subsequently placed a large order. Shortly after his auspicious debut, Klein created a line of designer sportswear.

Throughout the fashion industry, word spread quickly about Klein and his sleek designs, which were now featured regularly in Vogue and Harper's Bazaar. In the early 1970s, he introduced his trademark jeans, which he elevated to designer status by cutting them tight and branding his name on the back pocket. A series of provocative advertisements (that had 15-year-old Brooke Shields cooing the line, "Nothing comes between me and my Calvins.") created a designer jean frenzy among consumers, who were purchasing over 40,000 pairs a week.

In 1982, by adding style and his logo to boxers and briefs, Klein conquered the underwear market. He blurred the boundaries between the sexes, designing masculine bikinis for women. In the late 1980s, Klein entered the fragrance market with the launch of Obsession and Eternity.

The Calvin Klein label expanded over time to include swimwear, accessories, hosiery, and eyewear.

Widely considered the most prominent American fashion designer, Klein was first awarded the Council of Fashion Designers of America Award for outstanding design in both womenswear and menswear in 1982, becoming the first designer ever to receive both honors in the same year. Klein is the designer of choice for celebrities such as Julia Roberts, Gwyneth Paltrow and Helen Hunt, and has influenced designers such as Miuccia Prada and Donna Karan.
