    The narrowing of field of vision is due to magnification at all angles of gaze. Increased add power also...

    Comparing refractive index only, (1.50 - 1.00) / (1.60 - 1.00) = 0.83 or 17% thinner. But the surfacing center or edge thickness inputed will be the deciding factor, not the refractive index. One...

    No. In the USA, it's lighter because it can be surfaced thinner and still be as impact resistant as CR39.

    In general, as the density decreases, the index of refraction decreases. Conversely, the...
