In the New York Times Well blog, Tara Parker-Pope wrote that a study published in the Archives of Ophthalmology compares patch therapy for amblyopia with .a weekly regimen of medicated eye drops that essentially work as a patch by blurring vision in the stronger eye.
Mitchell M. Scheiman, O.D., FCOVD, of the Pennsylvania College of Optometry in Philadelphia, (now called Salus University) and colleagues, conducted a randomized study of nearly 200 children, and found that giving the eye drops on the weekend worked about as well as wearing a patch for two hours a day. The eye drops, which contain atropine, work by preventing a muscle in the stronger eye from constricting. As a result, when a child tries to read or focus on something close, the good eye is blurred. The child's weaker eye is forced to focus and work harder, which helps it strengthen over time.
