Dioptric Adjustment Lens with Eyecup
Ten eyesight correction lenses are available
in powers of +3, +2, +1.5, +1, +0 5, 0, —0.5,
— 2, —3 and —4 diopters. They may make
viewing and focusing easier if you are near or
farsighted. Choose the one which is closest
to your eyeglass prescription, and make a
practical test if possible.
