| These lenses are ASPHERIC, which
means that they are crystal clear from the center all the way to the edges. Most
lenses, by nature of the law of optics, are clearest when you look through the
center of the lens. As you look toward the edges, the lens tends to distort.
ASPHERIC lenses are designed so that there is little or no distortion,
whether you look toward the left, right, upper or lower edges. This can be helpful
in conditions such as macular degeneration. |

bifocals
my husband has a pituitary tumor...his vision is effected
The 5+ bifocals help some - though the focal length is quite short, he can read some things.
He loves to read books and even with these it is not possible. But for now they are the best things he has
