Smart Contact Lenses (SCL): The future of intelligent contact lenses – Augmented Reality (AR) and Extended Computing (XC)

From AR to health: The diverse applications of intelligent contact lenses

Smart contact lenses are an emerging technology that has the potential to go far beyond traditional vision correction. These innovative lenses combine advanced electronics and sensors with the functionality of conventional contact lenses, opening up a variety of new applications. From augmented reality (AR) to medical monitoring to sports performance optimization – the possibilities seem almost endless. Companies like Mojo Vision and Xpanceo are at the forefront of this development and are working hard to bring this technology to market.

Functionalities and applications of smart contact lenses

Augmented Reality (AR) and Virtual Reality (VR)

One of the most promising applications of smart contact lenses is in the area of ​​augmented reality (AR). By integrating AR technologies, these lenses can project virtual information directly into the wearer's field of vision. The *Mojo Lens*, for example, uses a micro-LED display with an extremely high pixel density of 14,000 pixels per inch (ppi) to display razor-sharp images. These images appear as if they were projected directly onto the retina, allowing the user to view digital content such as videos, graphics or text without the need for additional devices such as glasses or headsets.

This technology could find application in many areas of daily life. In a professional context, for example, intelligent contact lenses could be used to display information in real time - for example during surgical procedures or complex technical work. They could also enable a new way of learning in education, where students see interactive content right in front of their eyes.

Medical monitoring

Another important application area for intelligent contact lenses is health monitoring. These lenses are able to measure and monitor important physiological data. Of particular note is the monitoring of blood sugar levels in people with diabetes. The lenses can measure glucose levels in tears and alert the wearer if levels are outside the normal range. This offers a non-invasive alternative to conventional methods of measuring blood sugar and could make everyday life much easier for diabetics.

Smart contact lenses also offer promising options for people with glaucoma. They can monitor intraocular pressure, which is crucial for the early detection and treatment of this disease. By continuously collecting data and sending it wirelessly to a connected device, these lenses enable close monitoring of health status without the need for active intervention from the patient.

Improving vision for people with visual impairments

In addition to monitoring health data, smart contact lenses also offer solutions for people with visual impairments. Some models are designed to improve vision electronically. They increase the contrast of images, sharpen edges or enlarge text - all in real time. These features could be particularly useful for people with age-related macular degeneration (AMD) or other degenerative eye diseases.

The ability to improve vision through technology could help many people maintain independence in everyday life. It is conceivable that intelligent contact lenses could one day replace conventional visual aids such as glasses or magnifying glasses.

Sports and performance optimization

Intelligent contact lenses also offer exciting possibilities in the area of ​​sports. This technology would allow athletes to access important training data in real time - such as their heart rate, running speed or calorie consumption. This information could be displayed directly in the field of view without the athlete needing an additional device such as a smartwatch or smartphone.

Additionally, smart lenses could help improve concentration during training or competition. By minimizing visual distractions or providing targeted cues, they could help athletes optimize their performance and reach their goals faster.

Technological challenges on the way to market readiness

Despite the impressive progress in smart contact lens development, manufacturers still face some significant challenges.

power supply

One of the biggest hurdles is powering these sophisticated devices. Because the lenses need to constantly process and display data, they need a reliable power source. Some prototypes use miniaturized batteries, but these must be small enough to be integrated into the lens while providing enough power to maintain operation for extended periods.

Innovative approaches to solving this problem include using energy production through eye movements or even sunlight. However, such technologies are still at an early stage of development and need to be further improved before they can be used in marketable products.

Miniaturization and comfort

Another challenge is the miniaturization of electronic components. Smart contact lenses must not only contain all the necessary sensors and displays, but also be comfortable enough to be worn for long periods of time. This requires flexible materials and extremely small components.

While some companies like InWith Technologies use flexible microelectronics, other manufacturers like Mojo Vision rely on harder scleral lenses - larger lenses that sit on the white part of the eye (the sclera). While these provide more space for electronic components, they may be less comfortable than traditional soft contact lenses.

Hygiene and safety

Because smart contact lenses are worn directly on the eye, hygiene is crucial. There is an increased risk of infection or irritation from buildup of proteins or fats on the lens surfaces. Manufacturers must therefore ensure that their products are safe and do not pose any health risks.

Another important aspect is the security of data transmission. Because many smart contact lenses are intended to communicate wirelessly with other devices - whether to display AR content or transmit medical data - extensive security measures must be taken to ensure the protection of sensitive information.

When are smart contact lenses coming?

It will take a few years before this technology is ready for the market. Companies like Mojo Vision and Xpanceo are working hard to perfect their prototypes and are planning clinical trials and market launches within the next few years. It is expected that the first marketable products could be available by 2026.

In the long term, this technology could fundamentally change the lives of many people - both in the medical field and in everyday life. Smart contact lenses could not only improve the lives of people with visual impairments, but also create new possibilities for AR applications - be it at work, in sports or just for entertainment.

It remains to be seen what technological breakthroughs can be achieved in the coming years and what new application possibilities will arise as a result. What is already clear, however, is that intelligent contact lenses have the potential to fundamentally change the way we see - both literally and figuratively.
