Diabetics can simply control their glucose levels by blinking thanks to new smart contact lenses that monitor fluid in the eye and share reports wirelessly.

The new invention is being developed by Pohang University of Science and Technology researchers in South Korea as an alternative to blood tests.

The wireless and remote-operated lens could also allow medication to treat diabetes, released in the future, directly in the eye.

The device, which uses chip technology, monitors sugar levels through blood vessels behind the eyelids to alert the user about health conditions.

Scientists say the new tech represents the first potential use of contact lenses to monitor and treat symptoms of diabetes with a remote medical device.

There are several benefits of using a smart contact lens in the treatment of diabetes, according to South Korean researchers.

They say the glasses could provide an alternative to invasive blood tests, while also paving the way for the treatment of certain eye diseases.

Specifically, it could be used to dispense drugs via the eye to treat diabetic retinopathy, a complication of diabetes caused by damage to & # 39; blood vessels to & # 39; the back of the eye, says lead author Dr Do Hee Keum.

When testing with rabbits, the lens offered noninvasive monitoring of glucose and controlled drug delivery for the condition.

& # 39; We have developed smart contact lenses for both continuous glucose monitoring and treatment of diabetic retinopathy, & # 39; said Keum. & # 39; Our smart contact lens has a unique function of delivering ocular medicine. & # 39;

Smart electronic contact lens devices have been widely investigated for diagnostic applications, especially for continuous glucose monitoring.

In 2014, Google announced a project to develop a Google Contact Lens that was designed to help people with diabetes by measuring glucose levels in their trials.

Despite intense efforts for the commercial development of the & # 39; Google lens, they reported insufficient consistency in their measurements of & # 39; e correlation between tear glucose and blood glucose concentrations.

& # 39; The disappointing clinical results can be associated with the challenges of getting reliable readings of trials in & # 39; a complex environment in view, & # 39; Dr Keum said about the Google findings.

& # 39; We believe that with proper calibration and baseline monitoring, changes in glucose concentrations can be measured reliably for each patient. & # 39;

The team claims that the surface of the cornea provides a unique and convenient window to monitor physiological changes in the body.

This increased their interest in smart contact lenses for their potential healthcare applications such as glucose monitoring.

& # 39; The surface of & # 39; & # 39; e cornea uniquely presents an easy and non-invasive interface for physiological conditions in the human body, & # 39; Keum said.

& # 39; The eyes are directly connected to the brain, liver, heart, lung and kidney and can serve as a window to the body. & # 39;

The researchers wanted to design a model that could perform both this function and dispense drugs via the eye.

Smart electronic contact lenses have been widely investigated for diagnostic applications, especially for continuous glucose monitoring.

They developed a smart contact lens that includes a real-time electrochemical biosensor, an on-demand flexible drug delivery system, a wireless energy transmission system, and a remote radio frequency communications system.

In & # 39; study they have lenses in & # 39; inserted eyes of live diabetic rabbits and injected two units of insulin 15 minutes later to & # 39; the blood glucose level of & # 39; to reduce rabbits.

They then checked the changes, repeated the test after the 63 days lenses were tested to demonstrate their ability to remain stable over time.

Next, the researchers used the lenses to treat genistein, a drug used to treat diabetes, on & # 39; eyes of & # 39; released rabbits in the distance.

They measured the concentration after one hour, and found that the lens provided the drug as effective as an eye injection.

Dr Keum and her team also used an infrared thermal camera to test the design for safety, noting a little variation in & # 39; the temperature of & # 39; a lens.

But they note that further research will reveal if this smart contact lens can serve as a next-generation wearable device to promote diabetes health care.

Dr Keum said: & # 39; This smart theranostic contact lens will be further investigated as a next generation portable device to achieve real-time biosensing of ocular biomarkers and on-demand medication for healthcare applications only for various ocular and other diseases. & # 39;

The research was published in the journal Science Advances.

In the UK, about 90 percent of diabetic adults have diabetes 2

Diabetes is a lifelong condition that does not increase a person's blood sugar levels.

There are two main types of diabetes:

Type 1, where the body's immune system attacks and destroys cells that produce insulin.

Type 2, where the body does not produce enough insulin if the body's cells do not respond to insulin.

Type 2 diabetes is much more common than type 1.

In the UK, about 90% of all adults with type 2 diabetes have.

Reducing the risk of type 2 diabetes can be achieved through healthy eating, regular exercise, and reaching a healthy body weight.

The main symptoms of diabetes include: feeling very thirsty, urinating more often (especially at night), feeling very tired, weight loss and loss of muscle mass.
