These measurements can provide valuable insights into conditions such as stress, fatigue, and even neurological disorders.

The centerpiece of this technology is a miniature eye-tracking system incorporated into the contact lens. This system captures high-speed images of the eye and uses advanced algorithms to analyze the data. The challenge lies in developing a system that is not only accurate and fast but also fits comfortably into a contact lens. Companies like Mojo Vision are attempting to overcome these hurdles, pushing the boundaries of what’s possible with AR contact lenses.

Drug Delivery Systems in AR Contact Lenses

The concept of using contact lenses for drug delivery has been around for a while. Scientists have been exploring the possibility of using lenses as a medium to deliver medication to the eye, particularly for conditions like glaucoma and dry eye syndrome. What’s exciting about AR contact lenses is that they could potentially take this concept a step further.

AR lenses could incorporate micro-reservoirs or nanostructures capable of releasing medication directly into the eye. The release could be controlled via an external source or triggered by certain physiological parameters. For instance, a rise in intraocular pressure could trigger the release of medication, providing real-time treatment for glaucoma patients.

This application of AR lenses offers a non-invasive alternative to traditional drug delivery methods. It could enhance the effectiveness of treatment by ensuring a consistent drug concentration in the eye. However, there are several challenges to address before this becomes a reality. These include ensuring the biocompatibility of the materials used, maintaining the stability of the drug within the lens, and controlling the rate of drug release.
