Johnson & Johnson (J&J) has recently submitted a series of patent applications to the United States Patent and Trademark Office (USPTO) that focus on electronic content lenses. The company is known for its personal care and pharmaceutical products, but has lately directed its attention on innovations related to eye care. The list of J&J’s patents includes lense technology which would create a theromchromic shield that protects the eye from excessive sunlight. Another patent for contact lenses would utilize crystal elements, which would refract light and improve overall vision for the user. Two other patents related to eye care are design to prevent dry eye: one is a punctal plug that blocks drainage of the tear duct; the other is a fatty acid composition.
Patents specifically related to electronic contact lenses includes a lense with an event coloration mechanism that adapts to ultraviolet radiation exposure, pH fluctuations and reactions with pathogens to provide a form of light therapy. Another lens includes a unique profile and identifier that connects to a configured communication system. The system then transmits data to an external processor to deter counterfeiting. Once more design (although not directly relying on electronic components) would correct myopia and myopic astigmatism by utilizing corneal topography or wavefront data collected during corneal refractive therapy.
Along with patents focused in eye care, J&J has developed innovations such as a surgical implant to facilitate tissue repair and growth. Another recent development in personal skin care includes utilizing a plant extract from the seeds of a species found in tropical areas of the United States (Bursera simaruba). A topical product that includes this extract is claimed to help prevent signs of aging.
