How Eye Movements can help to spot a liar

People often say eye movements are one way to spot a liar.

Want to spot a lierBeneath this claim are ideas of right brain-left brain functioning. As the theory goes: A person looks up to the right when visualizing an imagined event (lying), and looks up to the left when visualizing a remembered event (telling the truth).

For a study, an international team of researchers investigated these ideas in order to find the truth.

What did the researchers discover? Liars blink less often than truth tellers, who in fact increased their blinking when answering questions.

In fact, using eye blink suppression to predict lying in another test case, the researchers correctly classified the liars 81.3 percent of the time.

Because this technique could be used secretly by using webcams and hidden cameras, the researchers believe their technique has great promise for the future.

Good for them, but most people prefer to upgrade their lie detection abilities minus the equipment.

Does Eye Colour Predict How You Respond To Pain?

Why do most people go to their doctors? One word: pain.

Does eye colour predict how you respond to painA geneticist at the University of Pittsburgh, discovered that women with blue or green eyes handle hurt better than those with brown or hazel eyes.

A study of 58 women who were expecting babies and planned to give birth at Magee Women’s Hospital was conducted. The researchers divided the women into two groups based on eye colour: 24 women in the dark group (brown or hazel eye colour) and 34 women in the light group (blue or green eye colour).

It was discovered that the women in the light-eyed group seemed to cope with childbirth the best. Not only did they become less anxious once their baby had arrived, they also were less likely to become depressed.

Other researchers in the field believe genes linked to melanin may strongly influence pain experiences; this pigment, found in the brain, is linked to darker-coloured eyes.

Researchers will be continuing to explore eye colour and pain experience. They are going to see if there is a link between eye colour and clinical pain… in men and in women, and in different pain models other than the labour pain model.

The effects only last for a short period of time, but medical experts warn that prolonged use can lead to a number of eye problems. According to medical experts at Today Clinic in Oklahoma City, The peppermint oil in the lip balm is a very strong irritant and can cause inflammation in the eye, redness of the eye and swelling.

This is the reason that many teens are turning to the lip balm for this type of satisfaction. It’s the peppermint oil that’s causing the burning sensation, and we suppose some people think that is kind of funny.

Beware: this is very bad for your eyes.

Sex hormone link to dry eye problem

Women with premature ovarian failure are more likely to experience dry eye symptoms.

Sex hormone link to dry eye problemAndrogen deficiency – shortage of male sex hormone – has been linked to dry eye syndrome in older people. A link between dry eyes and premature ovarian failure (POF) has also been uncovered. Women with POF also have androgen deficiency so perhaps this relationship is not surprising.

Researchers at the National Eye Institute looked at 65 women with POF and 65 without. The rate of dry eye syndrome in the POF group was 20 per cent, compared to three per cent in the controls. There was, however, no evidence of reduced tear production in the POF group.

The researchers believe that sex hormones somehow affect the state of the eye surface in a way not previously recognised.
