Contact lenses that can diagnose cancer. It’s a thing now. My first thought was that they’re like X-Ray glasses, somehow they’d let people see cancer on skin or something. That’s not how they work. People who might have cancer wear the lenses themselves. The contacts analyze tears, looking for chemicals that pop up during the early stages of cancer. And they think this might just be the start. According to the researchers, tears can be used to look for all sorts of bio markers. Apparently, these contact lenses will replace the current process that needs a lot of equipment and takes up to ten hours after analyzing other bodily fluids.
On a side note, while I was looking for a video to support this story, I ran across a newscast talking about how doctors found 27 contact lenses in a woman’s eye. All of them in one eye! And they wouldn’t have found them if they hadn’t been preparing her for cataract surgery.
