Diabetes : Lenses can detect blood glucose level

by Prince K. Live Happily After Diabetes

Monitoring the blood sugar level is very important for individuals with diabetes. But, it can be an obstacle for diabetics. Process of testing blood glucose level such as carrying a testing equipment, pricking your fingers, and feeling painful impacts due to the successive testing, checking your sugar level takes too much time. Due to this, specialists and diabetic analysts have been working to create simple, less-aggressive testing methods. Contact lenses are one of these simple approaches that help you to improve your vision and screen your glucose level.

Although, these lenses are not available on the open market recently, researchers are working on developing a version of these lenses that could be mass-produced and sold to patients with diabetes all around.

There are two types of lenses such as:

· Boronic acid based lenses and

· Photonic crystals based lenses

Boronic Acid Contact Lenses

Analysts have created a version of boronic acid- this is equipped for tying with sugar particles which can help measure glucose levels in the liquid of your eyes.

Liquid from the tear ducts has glucose; molecules in the boronic acid combine with sugar molecules in the liquid. The outcome is fluorescence, which will shine when light from a particular hand-held blue light is exposed on the eyes. As brighter the fluorescence, sugar level is also higher.

Photonic Crystals Contact Lenses

Scientists have additionally developed contact lenses utilizing photonic crystals that recognize and react to changes in glucose level. Any changes in blood glucose levels are reflected through a change of color in the contact lenses.

Photonic crystals are made of a blend of boronic acid and different chemicals. These chemicals make long polymer chains, which contain receptors that tie to the glucose structure. At the point when these chains come into contact with glucose (this glucose is present in the liquid of your eye), the spacing and volume are influenced, transforming how light passes through the material of the lenses. At the point when your glucose level is high and the level of glucose in the liquid of your eye is more accumulated, the polymer chains in your contacts will deliver a purple color. In that case when your glucose is low, the lenses will reflect a reddish shade. Ordinary glucose level would create a green shade.

These progressions in shade are on the base edge of the lens, i.e. they don't really influence the color of your eyes. You would need to see a mirror and look carefully at the lens to see what color is reflected and know about your blood sugar level.

Problems with contact lenses

Unlike the blood of your finger, tears do not show glucose levels rapidly. It acquires around 30 minutes for levels of glucose in the tears to achieve the level in the blood. Though, for various people who do prick each three to four hours, this should not be an issue as the numbers will be near to equivalent when you would be ready to test once more.
