Consider giving a speech without looking down at your notes; instead, the words scroll in front of your eyes in any direction you look.

That is just one of many features that manufacturers of smart contact lenses claim will be available in the future. Mojo’s Steve Sinclair is working on smart contact lenses. His company is about to begin extensive human testing of smart contact lenses, which will provide wearers with a heads-up display that appears to float in front of their eyes. The product’s scleral lens (a larger lens that extends to the whites of the eyes) not only corrects the user’s vision but also contains a tiny microLED display, smart sensors, and solid-state batteries. He claimed they had developed a fully functional, wearable prototype that will be tested very soon.

Smart lenses are being developed to collect health data. They can also provide options for extended-release drug delivery, which can help with checking and treatment plans. It’s exciting to see how far technology has come and how much it has the potential to improve patients’ lives. Researchers are working to develop lenses that can track biomarkers such as light levels, cancer-related molecules, and the amount of glucose in tears to check and treat medical conditions ranging from eye conditions to diabetes and even cancer.
