know ur glucose level by looking into ur eyes!!

The body can be a confusing place, and when you’re ill sometimes you just wish you could see what the problem is. For diabetics, that wish may be coming true. Professor Jin Zhang at the University of Western Ontario has developed contact lenses that would change color as the user’s glucose levels varied. The new device is made by embedding nanoparticles into standard hydrogel. These particles react with glucose in the tears and change color. The colour change is slight, but it could alert diabetics to dangerous sugar levels without the need for regular blood tests. According to the University’s News site.
While it could be very useful for diaetes in theory, the nanoparticle embedding process is probably going to find better applications outside of medicine. Passive monitoring through a contact lens, while ingenious, doesn’t seem like the most economic approach. And we’ve already seen how stem cell treatments, or implants, are likely to help fight or even cure diabetes in the future.

  1. " As you can see in the photo the effect is....." where is the photo?
    That's ok...... Will it affect the vision in any way?
