Also referred to as reading or
computer lenses, Nikon�s Online�
lenses provide the kind of maximum close-range vision
previously unthinkable. |
|
|
By extending your field of vision
laterally and towards the front, Nikon Online�
clarifies the focus of intermediate elements (up to
3 meters) such as a computer screen or person
sitting across you. This means that head and neck
movements are minimized, eliminating eyestrain and
helping to alleviate postural fatigue.
Online� is recommended for people with presbyopia
who wear contact lenses to correct far vision as
well as those who have been operated on for
cataracts. It can also be the perfect complement to
progressive lenses, when your near vision just isn�t
enough. |

Reliance on spectacles to give accurate
and comfortable vision at all distances generally
increases with age. Conventional progressive lenses,
especially those of Nikon quality, will allow accurate,
vision in all visual zones.
Wearing spectacles is, though, more than just about
clear vision. Long time use of intermediate and near
vision requires specialized progressive lenses able to
give wide vision in these areas and minimize the head
and neck movement common with less specialized lenses.
Single vision lenses do not give any flexibility on
viewing objects further away (up to 3 meters for Online)
and progressive lenses are not specialized enough to
give the width of vision required for comfortable
vision. |

Today, the demands on our eyesight are
greater than ever. For professionals, from hair stylists
to programmers, used to spending long hours in
close observation, Nikon Online�s effortless transition
from close to middle-range distance is a tremendous
asset.
Nikon onLine is for anyone whose hobbies
or pastimes require close attention to
detail. |

Online extends
vision over bifocals and standard
progressives for work-related tasks
Online is the new generation of reading
lenses, where the power gradually decreases
from the bottom portion of the lens (near
zone) towards the upper portion of the lens
(intermediate zone).
Bifocals offer a wide field of vision, but
they are strictly limited to a single
reading plane. Online extends the
width and depth of the field of vision,
making it possible to see objects beyond the
near zone, such as computer screens. The
focal power variation enables true
intermediate vision. |
