Lens Types

Single vision- Single vision or view lenses are generally used for correcting one field of vision, namely distance, intermediate (computer) or near. Younger individuals will be able to wear their single vision lenses all day whereas some older individuals will require different pairs for different tasks.

Bifocals - A Bifocal is a lens designed for distance and near vision. These two different prescriptions are divided by a line which is visible on the glasses. The section above the line would be for distance vision and the section below the line would be for near vision.

Multifocals - A multifocal (also known as a progressive or Varifocal lens) is a lens that allows for clear distance, intermediate and near vision. The prescription is varied through the lens to allow for a smooth transition between the different fields of vision. A multifocal has no visible line on the lens as a Bifocal does.

Torga Optical manufactures multifocals using the very latest German precision technology - high definition free form technology.

This manufacturing technology offers not only the clearest lenses but also the widest fields of views. - You get more clarity (pixels) with these lenses and more comfort.

This is in stark contrast with multifocals manufactured with the old technology, which is more than 30 years old, resulting in your lenses having narrower widths of views.

All Torga FlexiVue multifocals are manufactured using this latest high definition digital process giving you the most pixels possible for every view.

And whereas many other optometrists may offer these HD digital lenses as a premium product, Torga Optical offers this technology for all multifocals and lens materials. We cut out the middle man and pass on to you the very latest technology and our everyday low pricing.

 

Lens Materials

To understand why the material that your lens is made of matters, you could think of the lens material the same way you think of the material used in a wine glass.

You could have a wine glass of cheap material, or you could have a high quality glass made of fine glass. One looks cheap, brittle and is not very clear, the other looks tremendous and is very clear.

So the first point is that the chemical compositions of various lenses may not be the same – you probably thought they were – but with lenses you will certainly feel the difference.

Torga Optical considers four main factors in recommending lenses - the cosmetics or shape of the lens, the clarity, the weight, and the strength of the lens. All these factors will contribute to the comfort that your experience with your lenses.

Some of the commonly used latest technology materials include: CR39polycarbonateTrivexMr 8MR 10MR 1.74 and glass – these are high quality materials used by Torga Optical.

The Torga Optical Latest Technology Lens Guide available in stores indicates clearly what the lens material options are, and the best option for each lifestyle. These are all latest technology lens materials.
