Apple's efforts to develop a non-invasive glucose monitoring feature for Apple Watch are still 'many years away' from being available.
The idea originated during Steve Jobs era for an Apple Watch sensor to help users identify prediabetes and take proactive steps to reverse the condition.
Apple has been working on developing a method that uses optical absorption spectroscopy to determine glucose concentration without skin puncturing.
Despite reaching a proof-of-concept stage in 2023, the technology is still too large to incorporate into the Apple Watch.
