A smart contact lens with a built-in visual display is designed to magnify images for people with low vision. The patented lens, designed by a company called Mojo Vision, can project content from a smartphone.
The smart contact lens is a regular hard or soft contact lens surrounded by a liquid crystal display, a tiny controller ASIC (Application-Specific Integrated Circuit), a light sensor, an accelerometer and gyroscope, and a very thin solid-state lithium-ion battery.
Smart contact lenses are used for various applications, such as myopia, hypoxia, and other eye disorders.
Smart contact lens market is expected to reach a value of USD 678,147.91 thousand by 2030, at a CAGR of 12.6%. The micro-LED display contact lenses segment is expected to dominate the global smart contact lens market with the increasingly advanced technology and rising strategic initiatives by major market players.
The world of technology is constantly evolving, bringing innovative solutions to enhance our lives. One such groundbreaking invention is the smart contact lens. This cutting-edge technology combines the convenience of contact lenses with the capabilities of modern electronics, revolutionizing the field of vision correction. In this article, we will explore the concept of smart contact lenses, their potential applications, and the benefits they offer.

What are Smart Contact Lenses?
Smart contact lenses are advanced, wearable devices that are placed directly on the eye, just like traditional contact lenses. However, they go beyond vision correction by integrating miniature electronic components into the lens. These electronic components can include sensors, microchips, and tiny displays. The lenses are designed to be lightweight, comfortable, and unobtrusive, allowing users to enjoy a seamless experience.
How Do Smart Contact Lenses Work?
Smart contact lenses utilize various technologies to provide additional functionalities beyond vision correction. One important feature is the ability to measure and monitor various aspects of the wearer’s eye health. Sensors embedded in the lens can detect changes in intraocular pressure, glucose levels in tears, and even signs of certain diseases like glaucoma or diabetes. This information can be relayed to the wearer or healthcare professionals in real-time, enabling timely intervention and proactive healthcare management.
Applications of Smart Contact Lenses
Vision Correction
The primary purpose of smart contact lenses is to correct refractive errors, such as nearsightedness, farsightedness, and astigmatism. By integrating microelectronics into the lens, these devices can dynamically adjust the focal length, providing clear vision at all distances. This eliminates the need for multiple pairs of glasses or contact lenses, offering a convenient and versatile solution for vision correction.
Augmented Reality
Smart contact lenses have the potential to revolutionize the way we interact with the digital world. By incorporating miniature displays into the lens, users can have a heads-up display (HUD) right before their eyes. This opens up possibilities for augmented reality applications, such as displaying notifications, navigation directions, or even enhancing gaming experiences. The seamless integration of digital information into our natural field of view can greatly enhance productivity and convenience.
Biomedical Monitoring
The ability of smart contact lenses to monitor various aspects of eye health opens up new opportunities in the field of healthcare. For instance, these lenses can continuously monitor glucose levels in tears, eliminating the need for frequent blood tests for individuals with diabetes. They can also detect changes in intraocular pressure, aiding in the early diagnosis and management of conditions like glaucoma. The real-time data collected by these lenses can be shared with healthcare professionals, enabling personalized and proactive care.
Benefits of Smart Contact Lenses
Convenience and Comfort
Smart contact lenses offer a high level of convenience and comfort compared to traditional vision correction methods. They eliminate the need for bulky glasses or multiple pairs of contact lenses. Additionally, they provide a seamless experience by integrating electronic components into the lens itself, making them virtually unnoticeable to the wearer.
Enhanced Vision Correction
With their ability to dynamically adjust the focal length, smart contact lenses provide enhanced vision correction. This means wearers can enjoy clear vision at all distances, eliminating the need for multiple pairs of glasses for different tasks. Whether reading, driving, or working on a computer, the lenses adapt to provide optimal vision.
Early Disease Detection
By continuously monitoring eye health, smart contact lenses can detect early signs of various eye conditions and diseases. This enables proactive intervention and timely treatment, potentially preventing further damage or vision loss. The real-time data collected by the lenses can be invaluable in managing chronic conditions like glaucoma or diabetes.
