Nearsightedness, or myopia, as it is medically termed, is a vision condition in which close objects are seen clearly, but objects farther away appear blurred. There is currently no cure for myopia, but spectacles, contact lenses and refractive surgery can all provide good distance vision for people with myopia.
Eyeglasses are the primary choice of correction for persons with nearsightedness. Generally, a single vision lens is prescribed to provide clear vision at all distances. The prevalence of myopia in Spain seems to be somewhat lower than in Asia and Europe there are few comparable studies concerning the prevalence rates of hyperopia. 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.
