HEALTH ISSUE: SHORT CUT

SHORT CUTS


Plastic lens may soon
replace laser eye surgery


      Scientists from Moorfields Eye Hospital in London have come up with a novel  treatment to correct short-sightedness in people. According to the researchers, the new treatment changes the path of light entering the eye by using a synthetic lens inserted in front of the natural lens. Myopia or short sightedness is a condition where the eye focuses images in front of the retina instead of directly on it.This means objects further away appear blurred. "Our findings suggest phakic IOLs are safer than excimer laser surgery for correcting moderate to high levels of short-sightedness," the British newspaper Daily. Mail quoted lead author Allon Barsam as saying.


Poor sleep tied to dipping sex hormone:


       It's already known that levels of testosterone decline with age. But for the first time a new study has linked the decreasing levels of male sex hormone to lack of sleep in middle-aged men. Researchers at the Department of Psychology of the University of Montreal, Canada, found that testosterone levels begin to drop by 1% annually when men reach the age of 30. But it declines rapidly in men over 50 when the duration of their deep sleep decreases drastically, according to the findings presented at the annual conference of the Association francophone pour ie savoir.
