New Eye Device Could Replace CGMs for Blood Glucose Monitoring

Two physicists from Furman University in South Carolina received a patent for a new eye device that detects blood glucose levels. When released, the new technology could rival continuous glucose monitoring.  

Professor Bill Baker started working on the device in 2003 after he was diagnosed with type 2 diabetes. Baker noticed that after eating a meal, his vision became blurred. He learned that this was due to fluctuations in blood sugar levels. High blood sugar levels can cause the lens to swell, leading to blurred vision. 

Groundbreaking new device

Baker, together with infrared laser physicist Professor Paige Ouzts, developed a groundbreaking device which uses an infrared laser to take a picture of the eye. The body emits infrared light, so using this method the picture is able to detect blood glucose concentration in the fluid of the eye.

When the detecting technology caught up to their ideas, the duo was able to get the optical glucometer ready to patent. The patent granted for the device is the first in Furman University’s history. Now, the product will need to go through more tests before it can be released to the public.

If released, this new device will mark an easy, noninvasive way to quickly check blood sugar levels and store and share levels digitally. 


Type 2 diabetes 

Healthy bodies produce insulin in order to convert sugar into energy. Type 2 diabetes occurs when the body stops responding to the insulin produced in the pancreas. When this happens, blood sugar builds up in the bloodstream and damages tiny blood vessels throughout the body.

Symptoms of type 2

Type 2 diabetes can sometimes be symptomless and go undetected for years. If you have any of the following symptoms, talk with your doctor about testing your blood sugar to check for type 2 diabetes:

  • Increased thirst
  • Frequent urination
  • Increased hunger
  • Fatigue
  • Blurred vision
  • Weight loss
  • Slow-healing wounds
  • Areas of darkened skin around neck or armpits
