Light Intelligent Technology™ is a new contact lens technology applied by Johnson & Johnson Vision Care in cooperation with Transitions Optical Inc., a leading manufacturer of photochromic products. It's the foundation of an entirely new category of contact lenses with light-adapting capabilities previously only available in eyeglasses. It balances the amount of visible light entering the eye providing a better experience in a variety of conditions: outdoor or indoor, sunny or cloudy, during the day or from dusk until dawn. Light Intelligent Technology™ was trademarked by Transitions Optical Inc. on July 5, 2018, and is slated to be rolled out in 2019 as part of a new ACUVUE OASYS® lens category.
Light Intelligent Technology™ further explained
Johnson & Johnson Vision Care took the popular ACUVUE OASYS material and incorporated trillions of photochromic molecules by permanently bonding them to the lens matrix. When the lens gets exposed to UV or high-energy visible light, a chemical reaction causes these molecules to change their structure allowing them to dynamically absorb more visible light. When the UV and high-energy visible light are removed, most of the photochromic molecules return to their original state, while some remain active and continue filtering light. The whole process is quick and consistent regardless of the environment because the technology has been optimized to work at the temperature of your eye surface.
This lens is always on and - even when it appears clear - some photochromic molecules are activated and the lens filters light across the visible spectrum with an emphasis in the HEV range. Outside, when the lens is exposed to UV and high-intensity light, more of the photochromic molecules are activated and the lens immediately begins to darken in proportion to the amount of light that reaches it. Vice versa, in the absence of UV and HEV light, the lens quickly fades back allowing more light to pass through.
