C O M FE ATURE DEFINING A NE W MARKE T Design Principles and the Science of Attraction MEREDITH JANSEN, O.D., M.S., F.A.A.O. 1-DAY ACUVUE DEFINE Brand Contact Lenses with LACREON Technology were inspired by insights from Asia, where the beauty contact lens category makes up 18% of the overall contact lens market. Asian patients tend to have smaller horizontal iris diameters than Caucasians. Additionally, Asian patients who have narrow palpebral fssures have long been interested in making their eyes look bigger and brighter. We thought they were on to something important. The scientifc literature shows that not only do eyes play a major role in human attraction and communication, but that specifc features of the eyes, including white sclera and dark limbal rings, are particularly relevant. Humans are unique in having white sclera. Because of this, the contrast between the sclera and the iris makes direction of gaze more evident, helping people communicate with each other. 1 Whiter sclera is considered a sign of youth, health and attractiveness. 2,3 The limbal ring, which marks the border of the iris with the sclera, is thickest in infants and gradually gets thinner with age. 4 Researchers at the University of California-Irvine assessed the impact of the limbal ring on perceptions of attractiveness. When shown otherwise identical photos of male and female faces with dark limbal rings vs. no limbal ring, both men and women rated the faces with dark limbal rings as more attractive. 4 "Limbal rings are subtle but powerful signals of youth and health," says lead study author Darren Peshek, Ph.D., Research Director of The Odyssey Network Vision Science Research Lab. Enhancing the limbal ring to defne the iris edge and sharpen the contrast between the iris and the sclera is a key element in the design of 1-DAY ACUVUE DEFINE Brand Lenses. To develop the three variants — NATURAL SPARKLE, NATURAL SHIMMER and NATURAL SHINE — we used a combination of design principles based on science and the beauty needs expressed by women. In addition to incorporating a solid limbal edge for crisp and natural defnition, we sought to create iris-inspired patterns that incorporate highlights and shadows present in the natural iris. We specifcally wanted to have color contrast within the patterns and opacity and translucency to create blending and defnition. The result is a lens that accentuates natural beauty while supporting a healthy eye with BEAUTY WRAPPED IN COMFORT Technology. A transparent optical zone also helps maintain clear vision. 1-DAY ACUVUE DEFINE is built on the trusted platform of 1-DAY ACUVUE MOIST, and shares the same oxygen permeability and UV blocking. † * Dr. Jansen is Principal Research Optometrist, R&D;, for Johnson & Johnson Vision Care, Inc.

Spotlight on Science § Based on ftting data at ftting/dispensing visit in a randomized, cross- over, bilateral 4-visit study (n=252). Some patients may experience visual symptoms while wearing 1-DAY ACUVUE ® DEFINE ® Brand Contact Lenses † Helps protect against transmission of harmful UV radiation through the cornea and into the eye. *WARNING: UV-absorbing contact lenses are NOT substitutes for protective UV-absorbing eyewear, such as UV-absorbing goggles or sunglasses, because they do not completely cover the eye and surround- ing area. You should continue to use UV-absorbing eyewear as directed. NOTE: Long-term exposure to UV radiation is one of the risk factors asso- ciated with cataracts. Exposure is based on a number of factors such as environmental conditions (altitude, geography, cloud cover) and personal factors (extent and nature of outdoor activities). UV-blocking contact lenses help provide protection against harmful UV radiation. However, clinical studies have not yet been done to demonstrate that wearing UV- blocking contact lenses reduces the risk of developing cataracts or other ocular disorders. Consult your eye care practitioner for more information. Please see page 4 for more important prescribing information.
