Luminous contact lenses for people with diabetes

Diabetes is the scourge of our planet that has hit hundreds of millions of people. It is accompanied by serious adverse pathologies. Among other things, there is a high risk of slow vision loss due to cell death in the blood vessels located in the region of the eyeball.

You can more or less successfully fight visual impairment with a variety of laser and invasive therapy technologies, but researchers are working on the most effective techniques. A team from the California Institute of Technology (Caltech) has demonstrated its own development.

Specialists have created specific non-invasive contact lenses. They could potentially become an obstacle to the gradual decrease in the vision of patients affected by retinopathy – loss of vision due to diabetes. It develops because the nerve cells in the retina lack oxygen.

In the presence of diabetes, this problem becomes especially serious. The appetite of nerve cells is increasing, leading to the death of vessels located in the area of ​​the retina. The patient begins to lose sight.

A breakthrough in the fight against progressive blindness may be luminous contact lenses developed by researchers. As scientists have established, the main risk factor in this case is the stem cells located in the retina. At night, they consume almost twice as much oxygen as daytime. As a result, cells and blood vessels die off faster.

Now, stem cells will be able to absorb light directly from contact lenses. Experts clarified that there are several side effects.

However, they compared their development with the usual invasive technologies, such as laser correction. The side effects of the new items are much less, and the effectiveness is much higher. So, having saturated the appetite of stem cells in the retina, the scientists were able to significantly reduce the dynamics of the overall process.

The blood vessels located in the eyes will die more slowly. So, we can hope for the latest method of therapeutic treatment.
