Smart Contact Lenses
Smart contact lenses, such as those in development by Mojo, use a tiny micro-LED display the size of a grain of sand to display information to the wearer (augmented reality). The lenses, which are still in development, include smart sensors powered by solid-state batteries built into a scleral lens that can correct the wearer’s vision.
Mojo notes that while there is a broad acceptance of wearable technology, other wearables have limitations. Mojo’s research found that 68 per cent of respondents find it often difficult to check a device during a workout. Mojo’s smart contact lenses may have an advantage over smartwatches and fitness bands because users don’t have to interrupt their activity to check them. They can also provide better access to data during performance. Although Mojo’s current focus appears to be using the lenses for sport, they could have many other applications.
Other companies are also developing their own versions of smart contact lenses. Samsung, in 2016, patented smart lenses capable of recording video and taking pictures. Sony is also known to have been experimenting with smart contact lenses for many years.
Specsavers note that smart contact lenses could help manage the five most common eye conditions in the future: cataracts, glaucoma, diabetic retinopathy, macular degeneration, and retinal detachment. Specsavers state that smart contact lenses already offer a non-invasive way to monitor glucose and capture spontaneous changes in the eyes to help doctors treat glaucoma.
Smart Glasses
The smart glasses market has seen much development in recent years.
Google’ Glass’ is the tech giant’s smart glasses product. ‘Glass’ incorporates cameras and provides the wearer with AR displays and information in their peripheral vision area. A wide variety of industries can use the Enterprise Edition glasses to give workers hands-free access to information while working and enables them to share what they are seeing (via the camera). ’Glass’ smart glasses have been used in healthcare, warehouse order picking, supply chain management and logistics. Google’s ‘Meet on Glass’ also allows meeting participants to experience a first-person view of the Glass wearer’s perspective and collaborate with the video meeting in real-time.
Vuzix has developed smart AR binocular glasses to enable business owners, operators, and workers access to ‘the metaverse’. Vuzix’s glasses can access AR tools in healthcare (surgeons while operating), warehousing (helping with stocking, order picking and real-time decision-making support), field service, and other industries. The company also says that its glasses can link with collaborative working and communications platforms. In 2019, Vuzix also developed smart glasses that incorporated facial recognition algorithms that could be used by security and law enforcement for covert surveillance.
Meta / Facebook Ray-Ban’ Stories’ smart sunglasses incorporate dual integrated 5MP cameras enabling the wearer to take photos and up to 30-second videos using a capture button or hands-free voice commands. Meta says that the glasses also allow the wearer to share their “adventures” and listen to music or take phone calls.
Challenges
There are, however, several challenges to the expansion and further development of wearables like smart contact lenses and glasses. These challenges include:
- Compliance with privacy laws such as GDPR. Glasses that take pictures and videos of people without their consent and how those pictures and videos are stored and shared are a matter for privacy regulations.
- The nanotechnology involved in smart contact lenses and how to link the different technologies together successfully is a significant challenge, which is one of the reasons these types of smart wearables have taken years to develop.
- Getting approval for the use of smart optics in specific settings, such as in healthcare, may take time in different countries.
- Marketing what are essentially new, high-price specialized products such as smart glasses is a challenge.
What Does This Mean For Your Business?
The use of smart optics in many different industries has improved effectiveness and productivity. It allows better real-time problem-solving and communication, which can add value and improve competitiveness for businesses. Smart contact lenses are an interesting and exciting development in hands-free AR assistance for workers, athletes, and even as a way to monitor eye health and help catch potentially serious eye conditions early on. Also, the fact that they are not outwardly visible (like glasses) may make them particularly well-suited to professions where surveillance is required. There are challenges, both technical and legal (privacy), to overcome before the further development and wider use of these types of wearables can start to enter the mainstream with greater regulation expected along the way.
