The glass lens can show the function of inhibiting the development of ametropia of the eyes and simultaneously can ensure full visibility and good wearing feel. The glass lens comprises first refraction areas and second refraction areas, wherein each first refraction area has first refraction force based on a prescription for correcting the ametropia of the eyes; each second refraction area has refraction force different from the first refraction force and has the function of focusing pictures on the positions except the retina of the eyes to inhibit the development of the ametropia of the eyes, wherein near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.
