Varifocal Lenses

Progressive Power Lenses (PPL), commonly known as ‘Varifocal’ lenses are generally recommended by Optometrists and Dispensing Opticians when you have a two prescription requirement. Typically, one for distance vision and one for near vision.

These lenses are designed in a manner that they have a gradual change incorporated into the strength of the prescription from the top of the lens where the distance portion is set, to the bottom with multiple focal points allowing you to see clearly at all distances through just a single lens.

This effectively means that you don’t need to purchase two pairs of glasses for two different distances.

In comparison to traditional bifocals, they don’t contain a reading segment as such with a visible dividing line. This eliminates ‘Jump’ (difference in sudden magnification between focal lengths) from within the lens which makes them much more functional and cosmetically pleasing. Also, they disguise age very well as onlookers cannot tell the type of lens you’re wearing.

There are 3 portions to a varifocal lens:

Distance Portion: Where the distance component of your prescription is set

Intermediate Portion: The progressive portion between the distance prescription and the

near prescription. Also referred to as the ‘Visual Corridor’.

Near Portion: Where the reading/close up component is set.

Varifocal lenses are generally very easy to adapt to p
