The CENTRAFORM process makes it possible to manufacture aspherical lenses of extremely high quality.

With spherical lenses, spherical aberration can cause blurriness because the focal point of light rays passing through the lens varies according to the ray's distance from the lens center.

With 1day Miru aspherical lens design, spherical aberration is minimized; light rays come together at the correct focal point to ensure a sharper, clearer view.
