Exercises using a cable puts muscles under a constant tension. With free weights, the angle of joints are often changing, thus the resistance on the muscle is also changing. Under constant tension, blood flow is often increased, thereby resulting in quicker and bigger pumps.
News. Premature birth causes blindness among babies. Consultant eye surgeon at the Eye Hospital and co-ordinator of childhood blindness, Dr. (Ms.) Mangala Gamage said the new cause for blindness is Retinopathy of Premature babies (ROP), a disease of the retina among prematurely born babies.
Every year, millions of children throughout the world. are born with eye birth defects that cause cloudy corneas. The lack of surgical intervention will result in permanent blindness for a child born with cloudy corneas. The cornea is the window of the eye. Light travels through the cornea to the retina, which sends impulses to the brain, allowing vision to develop. Visual development takes place until age eight and then stops. If the cornea is cloudy, which can be caused by an eye birth defect, light cannot reach the retina and impulses cannot reach the brain, resulting in lack of visual development. Without a corneal transplant the infant will become permanently blind.
