New research suggests that contact lenses may be able in future to diabetic patients monitoring their blood glucose levels. They would change the work of their appearance changed in line with the carrier blood sugar levels.
Currently, diabetics have to draw blood and to track changes in their blood sugar levels. This is painful and unpleasant. Monitoring of blood glucose through the changing appearance of contact lenses would be a lot lesspainful alternative. It is also a logical next step, such as diabetes often affects vision, "meaning that they wear glasses or contact lens wear.
These lenses work by changing levels of glucose sensing in the blood of the wearer. They contain boronic acid, which respond to glucose carrier 'tear glands produce fluorescence. With shining a blue light in her eyes the carrier can gauge the intensity of the fire, draw their blood outBlood glucose.
Another option that would change under examination, which would work in a similar way, is a color contact lens. This change, from green to yellow to orange to red. As a result, the carrier would be able to provide a more accurate reading of their blood sugar levels.
Although the level of glucose in tears lasts about half an hour to meet the body's blood sugar levels, the researchers have not, that this would be a problem. This is because the majority of diabetics have(Hour long breaks or more) between the blood tests. Therefore, the contact lens approach would be more timely.
Although there is not already covered by other glucose-monitoring system that tingling sensation on the skin can leave this method offers a significant advantage over current models.
The existing model is worn as a bracelet and apply a small electrical current to the skin. This draws the liquid that sits between the cells through the skin so that it can be tested for glucose. TheThe disadvantage of this method of glucose testing contact lens is compared to that manufacturers continue to recommend that users perform random blood tests.
