Choosing new spectacles is now easier than ever before. The visioffice system can take precise measurements, take photos and video and help demonstrate lenses, lens coatings, and frames.

Spectacle Lenses

Up until now you might not have given much thought to your lenses. To many people, selecting spectacles is all about choosing a frame, but it’s worth remembering that it is the lenses that enable you to see clearly! In simplistic terms, lenses come in three formats, single vision, bifocal and varifocal all of which offer very different functions to the wearer.

In 99% of cases, this is what the first time spectacle wearer will require. As the phrase suggests, single vision lenses offer a single focal power and correct close-up or distance vision. Typically, single-vision lenses are worn for reading if you are long sighted and for distance if you are short sighted.

Bifocal lenses

There will come a time in your life when you may need glasses to improve both close-up and distance vision. One option is to carry two pairs of spectacles around but this is inconvenient and frustrating. Bifocals are two lenses in one, enabling the wearer to see clearly at close-up and distance, but not in between.

Varifocal lenses

Sometimes known as “bifocals without the lines”, Varifocals are, in fact, much more as they offer complete vision at all distances including intermediate and look better cosmetically.
