About Sponsor:

Transitions Optical was founded in 1990.[1] In 1991, Transitions Optical became the first company to commercialize and manufacture plastic photochromic lenses.[2] Transitions lenses are also called adaptive lenses. They are clear indoors and at night and automatically darken outdoors as light conditions change. They block 100% of UV rays and help to enhance contrast and reduce glare.[3] In addition to original Transitions lenses that are for everyday wear,[4][5] Transitions Optical also makes Transitions XTRActive lenses that change from light tint indoors to very dark outdoors and are only available in North America,[6] and Transitions SOLFX sun lenses that go from dark to darker outdoors depending on the sun and are available worldwide.[7][8] Throughout the 1990s, Transitions Optical established offices in Europe, Asia/Pacific, South America, Australia and Canada. Transitions Optical has more than 1,200 employees worldwide and offices throughout 15 countries.[9]
