Invisible Optical Lens

The upper part of the bifocal lens is the luminosity used to see far, and the lower part is the luminosity used to see near, so that presbyopia patients do not need to change glasses frequently when looking far and near.

Bifocal (also can be called Multifocal) eyeglass lenses contain two or more lens powers to help you see objects at all distances after you lose the ability to naturally change the focus of your eyes due to age.

Although most bifocals and trifocals have visible lines at the border of lens segments, there is a blended round-seg bifocal that has a less noticeable near segment than its regular round-seg cousin.

The near seg is blended into the distance portion of the lens so that it is virtually invisible.

With no visible lines, a blended round seg bifocal offers a more youthful appearance than lined bifocals and trifocals.

Blended bifocals should not be confused with progressive lenses, which are special no-line multifocals that incorporate all corrections, from distance to close-up, into one lens without any separation of the various visual zones by lines.

How bifocal lens work?

Bifocal lenses are perfect for people suffering from presbyopia- a condition in which a person experiences blurred or distorted near vision while reading a book. To correct this problem of distant and near vision, bifocal lenses are used. They feature two distinct areas of vision correction, differentiated by a line across the lenses. The top area of the lens is used for seeing distant objects while the bottom part corrects the near-vision
