Hi, eyes vision power depends on natural lens present in our eyes. Due to weakening of these lens fibers causes short sightednes and long sightedness. When it happens it needs correction. refractionist will check vision every 6 months or yearly and give correction. Now a days laser surgery is also available for correction. Depending on cause it needs treatment. Consult opthalmologist for further evaluation and treatment.
