Translation of "Bifocal lenses" in German

Bifocal or multifocal lenses are not suitable for VDU work.

In addition, according to the state of the art bifocal or multifocal lenses are known.

Morrie rolled his eyes over his bifocal lenses.

Especially with progressive multifocal lenses or bifocal lenses the near addition, the so-called addition, is also provided.

Thus, Younger Optics could not only offer unifocal, but also bifocal and progressive lenses.

In addition to the standard use of DMD in the field of digital video projection, the device could also be put to other uses, for example the measurement of bifocal con­tact lenses or checking for wear on DVD discs or CDs.

It is understood that spherical, toric and polyfocal lenses, for use in the human eye, including bifocal contact lenses, having powers covering the ranges from about -20 to about +20 diopters can be advantageously prepared by methods A, and B, described supra.

As the form, i.e. the design of the parallel surfaces, on which the refractive index is respectively constant, is no longer restricted by the selected process of production for the index gradient, aberrations may, by way of illustration by optimally corrected in accordance to the respective intention in uniform strength as well as varifocal lenses, i.e. bifocal or trifocal lenses, astigamtic lenses or progressive lenses.

Accuvue Bifocal contact lenses mean that there is finally a solution for those who need glasses for reading and for seeing in the distance.

Nowadays that computers have become an integral part of our lives, they have given rise to the need for acute sigh in an intermediate distance (50-60 cm) that is not covered by bifocal intraocular lenses.

In general, the same type of selection chart is used for every type of spectacle lens, such as, for example, (spherical and/or toric) single vision lenses, bifocal lenses, aspherical lenses and PALs.

Importance is attached in particular to bifocal spectacle lenses, namely multifocal spectacle lenses comprising two parts, usually for distance vision and near vision, and to progressive spectacle lenses, namely spectacle lenses comprising at least one progressive surface and an increasing (positive) power when the wearer of the spectacles looks down.

The production of the spectacle lens is preferably performed by means of a combination of the production methods developed for bifocal spectacle lenses and the production methods developed for individual spectacle lenses.

The production of a spectacle lens according to the first or the second embodiment, with an object-side surface of the prism portion integrated in the object-side surface of the spectacle lens as a “near portion”, may take place by means of the production methods developed for the production of bifocal spectacle lenses.

In contrast to the third embodiment, the spectacle lens is produced from a main body and a prism body of glass or plastics by means of the production methods developed for bifocal spectacle lenses.

The spectacle lens may be produced from a main body and a prism body of glass or plastics by means of production methods developed for bifocal spectacle lenses.

The optical lenses can be designed to correct for short-sightedness, to correct for long-sightedness, as bifocal lenses or as progressive lenses.

Bifocal or multifocal lenses having two or more fixed focal lengths installed in parallel are also known in ophthalmology, whereby, following a training phase and according to requirements, the patient concentrates on one of the focal widths, which are always available, according to the situation in order to favour sharper images.

What Are Bifocal Lenses?

For example, a child who uses his/her eyes alternately may be able to have distance correction for one eye and a near correction for the other, rather than the more costly bifocal lenses.

As per as variety of lenses are considered to suit your vision requirements, you can find zero power, bifocal, progressive lenses, polycarbonate and UV protected lenses.
