A pathway leading to a journey with reduced barriers

SIGNO Bifocal Lens:

Bifocal lenses are divided into two parts to accommodate a combination of any two different
prescriptions into one lens. One area of the lens will have one prescription (usually distance)
and a segment in the lower half will have the other (usually near vision).
Rather than having two pairs of single-vision glasses, Bifocal lenses can be a more convenient solution as they combine all your vision needs into one pair of glasses.
For example, if you work in an office you may want to have intermediate vision in the top of the lens for meetings or presentations, and near vision in the segment for looking at your computer screen. Or at a park you want to enjoy nature and also want to enjoy your newspaper SIGNO bifocal have get your needs covered.

The “ far segment” of the lens is for distance vision.
Your normal glasses prescription will go in
this part of the lens.
In flat top lenses “near segment is
unblended & visible”.

The “near segment” is for looking at things that
are near. Like built-in reading glasses in your
normal prescription.
Blended lenses are cosmeticaly attractive
as the segment is invisible.

Types of Bifocal at SIGNO

A flat-top bifocal has a small segment shaped like a half moon or the letter “D” on its side. It is positioned nasally and down toward the bottom of the lens. Depending on preference, a patient may choose between a 25 mm segment or a 28 mm segment. The top of the segment has a visible line in the lens.

Round Segment:
A round bifocal is a 25 or 28 mm round segment toward the bottom of the lens. This bifocal was developed to allow the wearer to reach the reading area of the segment a little easier. Round segments are not as commonly worn today.

Blended/Invisible bifocals are popular because no-lines visible. They are typically made of a round segment where the edges are blended in with the rest of the lens. While a trained optician can easily see it, to the rest of the world it is much less visible than a flat-top bifocal.
