When you think of "augmented reality contact lenses," you might imagine something out of a science fiction movie, like time machines or flying cars. Until Mojo Vision’s smart contact lens functional prototype was announced in 2022, although it is a piece of art, it does have its own stumbling blocks.

With the growing trend of augmented reality, more and more companies are trying to develop their own versions of this technology. So what time is better to talk about augmented reality contact lenses, aka ARCL, than now? And if these lenses become a reality, they have the potential to do more than simply enhance our vision. They could fundamentally change the way we perceive reality and interact with the world around us.

Mojo Vision’s Smart Contact Lens

Mojo Vision's smart contact lens features the world's tiniest MicroLED display, measuring a mere 0.48mm with a minuscule 1.8-micron gap between pixels. It incorporates an ARM processor, a 5GHz radio, an IMU equipped with an accelerometer, gyroscope, magnetometer, "medical-grade micro-batteries," and a power management circuit with wireless recharging components.

The lens boasts a comprehensive graphical user interface, displaying readable text and interface elements in a monochrome green hue. Positioned at the centre of the retina, the display ensures sharp, detailed visuals, complemented by impeccable eye tracking that keeps your gaze as the focal point.

Despite its advanced features, the lens faces challenges, primarily due to its rigid material, which causes discomfort during prolonged use. The lens's appearance when worn on the eye is somewhat unsettling, contributing to its less appealing aesthetic.

UNIST’s Smart Contact Lens That Monitors Glucose Levels

A group of scientists from South Korea's Ulsan National Institute of Science and Technology has successfully developed a smart contract that monitors glucose levels in real-time using a contact lens display. They created a soft lens that integrates glucose sensors, wireless power transfer circuits, and display pixels, all made from transparent stretchable nanostructure material, making it more manageable and safe to wear. The commercial use of these lenses could potentially revolutionize the medical field in the treatment of diabetes and diabetic retinopathy, providing a significant breakthrough.

Samsung is Developing AR Contact Lenses

Samsung filed a patent in 2016 for smart contact lens technology that could project images into the wearer's eyes. The design was created by a scientist in South Korea who works with augmented reality (AR). The lens has a tiny display, camera, and antenna and is capable of superimposing computer-generated images (CGI) over the real world.

The sensors in the lens can be controlled by blinking, similar to the technology used in smart eyeglasses and Google Glass, where the wearer can take photographs by winking. Samsung has also trademarked the name 'Gear Blink' in the US and South Korea.

The Promise of Augmented Reality Contact Lenses

Immersive Experiences  

Augmented reality contact lenses promise to deliver truly immersive experiences. Instead of looking at a screen, users can have information overlayed onto their natural field of view. Whether it's navigating a city, translating foreign languages, or receiving real-time updates, the possibilities are vast.

Enhanced Accessibility

AR contact lenses could offer a transformative solution for individuals with visual impairments. These lenses could provide real-time assistance by identifying objects, recognizing faces, and offering audible cues, ultimately enhancing the overall quality of life for those with visual challenges.

Discreet and convenient

Unlike traditional AR devices, contact lenses are discreet and convenient. Users won't need to carry bulky glasses or wear a headset. The technology seamlessly integrates into their daily lives, providing information without drawing attention or hindering their activities.

Health Monitoring

AR contact lenses could go beyond vision enhancement, incorporating health monitoring features. Imagine a lens that not only assists with your vision but also monitors your health by analyzing biomarkers in your tears. Early detection of various medical conditions could become a reality.

Challenges and Ethical Considerations

While the potential benefits of augmented reality contact lenses are exciting, several challenges and ethical considerations must be addressed. Privacy concerns, potential misuse of information, and the impact on human interactions are critical aspects that need careful consideration as this technology develops.

Final Thoughts

The future of vision is undoubtedly intertwined with the evolution of augmented reality contact lenses. As these tiny marvels continue to advance, our perception of reality and the way we interact with information will undergo a transformation. While we eagerly anticipate the positive impact on accessibility, convenience, and health monitoring, it is essential to approach this innovation with a mindful consideration of ethical implications.

In the coming years, the integration of AR into our daily lives through contact lenses may become a commonplace reality. As we inch closer to this future, the key lies in striking a balance between technological advancement and responsible implementation, ensuring that the benefits of augmented vision are accessible to all while safeguarding individual privacy and ethical principles. The journey towards the future of vision has just begun, and the possibilities are truly boundless.
