What is Ultex lens?
Ultex. The Ultex lens has been phased out in many mediums. This lens is also called the Baseball Segment and CX. The segment usually measures 38mm in width. The Ultex lens is another recommended occupational lens offering a vast reading range.
What is executive lens?
The Executive Bifocal is similar to the original Split Bifocal worn by Benjamin Franklin. The entire top portion of the lens is dedicated for distance use whilst the bottom portion is for reading. They offer a much wider reading area than other types of bifocal.
What is a blended lens?
Blended Lenses Bifocal lenses have two lens powers applied (one for distance and one for near vision). The advancement of blending technology means that the lens segments can now be blended so the division of the segments is less visible, flowing smoothly between distances rather than having rigid division.
What is multifunctional lens?
A multifocal lens is a lens that contains two or more prescriptions for correcting vision at different distances. These include bifocals, trifocals, progressives and special occupational lenses. As a result, multifocal lenses are often prescribed to adjust to these changes.
Can you get bifocals with no line?
Progressives, or “no-line bifocals,” have a gradual curvature across the lens surface and provide not only clearer vision at near and far distances, but also smooth, comfortable transitions in between. Today you can find factory molded progressive lenses at many major retailers and even on the Internet.
What is round top bifocal?
A round-top bifocal segment can be thought of as the top. half of a plus lens (and thus like a base-down prism) Likewise, a flat-top bifocal segment can be thought of. as the bottom half of a plus lens (i.e., a base-up prism)
Are multifocal lenses worth it?
Existing systematic reviews have generally concluded that multifocal IOLs result in better uncorrected near vision and greater spectacle independence, but more unwanted visual phenomena such as glare and halos, compared to monofocal IOLs.
Are blended lenses the same as progressive lenses?
Blended bifocal lens. This may be bothersome to some wearers. 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.
Are progressive lenses better than bifocals?
Progressive lenses provide a transition from near, intermediate, and far vision prescription. As compared to bifocal lenses, progressives provide a wider zone of clear vision to make activities like computer use and reading easier for the wearer.
Is multifocal same as progressive?
Progressive lenses have three prescriptions in one pair of glasses. They’re sometimes called multifocal lenses. Progressive lenses are an update on bifocal and trifocal lenses.
