The speed and degree to which the pupil of the eye responds is a standard test for alertness. It has also been used to assess how sleepy or exhausted a person is. Now, research to be published in the International Journal of Bioinformatics Research and Applications suggests that measuring pupil response alone is not enough and that a person's rate of blinking should also be incorporated to obtain a more precise measure of alertness. The work could be important in the care of people with multiple sclerosis and other conditions. It might also be automated and ultimately used to automatically monitor patients, drivers, pilots, machine operators or others. To see more details visit,www.medicalnewstoday.com
