New Contact Lenses for diabetics

Special contact lenses, which are able to detect unusual blood sugar levels in the eye, could offer diabetics a new non-invasive way to test their insulin levels without the pin-prick test.

By reducing the discomfort, inconvenience and cost, the researchers in Ohio believe that the new invention could improve compliance to blood sugar testing.

The lens is able to sense glucose in tears and will change colour if the concentration levels increase, thereby demonstrating poorly controlled diabetes. The researchers expect the contact lens to be able to help in improving control of blood glycaemic levels and even be able to help identify patients with ‘pre-diabetic’ conditions, allowing for early diagnosis which is crucial in preventing diabetes from advancing.

They hope eventually, to have a smart phone app which would allow wearers to take a photo of their eyes (wearing the contact lens) for immediate results.
