Diabetics may be saved from having to draw blood several times a day to test their sugar levels after scientists found a way to use tears instead.
Diabetics have to test their blood sugar levels from two to 10 times a day by drawing a droplet of blood with a finger-prick test.
However, some people don't measure their levels often enough because of the discomfort it causes.
Tear testing: Diabetics nay be able to measure their blood sugar levels from tears instead of having to use a finger-prick blood test
Now researchers at the University of Michigan have developed a sensor that can detect blood glucose levels in tears.
The study, which used rabbits as human substitutes, found glucose levels in tears correlated to glucose levels in the blood.

Could cutting back on salt do more harm than good? Experts find it raises cholesterol
Ask the doctor: How can I cure my bloated painful tummy?
The researchers said in the journal Analytical Chemistry: 'Thus it may be possible to measure tear glucose levels multiple times per day to monitor blood glucose changes without the potential pain from the repeated invasive blood drawing method.'
Some type 1 diabetics must check their blood sugar levels 10 times a day
Doctors say there is a great demand for an alternative to using lancets, or pricking needles, to draw blood.
Fingers can become sensitive over time and there is always a small risk of infection.
Frequent tests are essential for people with type 1 diabetes, who can't produce the hormone insulin, needed to control blood sugar levels.
Skin prick tests are the only way to safely monitor glucose levels and will let patients know if they need an insulin injection.
If blood sugar levels fall too low, type one diabetics can develop hypoglycaemia, which can lead to coma and death if left untreated.
People with type 2 diabetes don't produce enough insulin to control blood sugar levels. Although it can be treated with a healthier diet and exercise it is a progressive condition and medication may be needed when the condition is more advanced.
Those with type 2 diabetes may only need to test themselves twice a week if they manage to get their sugar levels under control.
Diabetes affects 2.8 million people in the UK and 26 million people in the U.S. The majority of sufferers have type 2 of the condition.

My blood sugar numbers have been very good 109-124, but then I started to take Anti-biotic which I don't trust and my blood sugar 142 at 11:30 AM and I calibrated and it was 120 I ate candy, but it needed to be Calibrated. I strongly believe there is a relationship between higher blood pressure and higher blood sugar although has agreed with me so far. I am happy when I check my blood sugar 4-6 times when I can remember to do so.
I hope this somehow relates to our topic here. I will get the better Chromium the next time I order it, it takes more of it to get the same results.
Interesting article though!
Don't like messin with the eyes though
