Myopia, commonly called shortsightedness, is a condition in which light is focussed in front of the retina, resulting in blurred vision. Shortsighted people can often see reasonably clearly at short distances, but will not be able to see distant objects clearly. There is currently no cure for myopia, but spectacles, contact lenses and refractive surgery can all provide good distance vision for people with myopia.
Wearing corrective lenses treats nearsightedness by counteracting the increased curvature of your cornea or the increased length of your eye in order to develop a protocol for measuring vitamin D levels, Mutti is conducting a study in which participants are wearing monitors that detect exposure to UV and visible light. Levels of vitamin D are also being measured via blood and saliva samples.
