What are varifocal glasses?

Varifocal Glasses, also known as varifocal lenses or progressive lenses, are used when you have two prescriptions, one for distance and one for reading.

This quick video explains in simple terms varifocal glasses:

How do varifocal lenses work?

Varifocal lenses work by having a gradual change in strength from the top of the lens to the bottom and multiple focal points in between. The upper part of the lens contains the distance power, the middle of the lens has the intermediate ranges and the lower portion, the reading part

Unlike bifocals, they do not contain a reading segment or dividing line within the lens.

This means the wearer doesn’t need to buy and care for 2 pairs of glasses or need to switch between glasses for different vision needs.

Below are the basic 3 regions of a varifocal lens:

Distance Zone: The ‘upper’ portion of the varifocal lens provides the ‘distance’ viewing area.

Intermediate Zone: The distance and reading areas are connected via a ‘corridor’ of intermediate powers and provides viewing for ‘mid-range’ vision.

Near/Reading Zone: The ‘bottom/lower’ portion of the lens provides the ‘close up/reading’ area

The different types of varifocal:

There are many different types of varifocals on the market offering numerous benefits and features dependent upon your lifestyle, needs and requirements.

  • Standard
  • Premium
  • Free form
  • Occupational
  • Lifestyle
  • Elite

Standard varifocal:

Standard Varifocal lenses are the ‘entry level’ varifocal options and are chosen as an enhanced alternative to bifocals. They have clear vision and fairly wide focal areas for distance, reading and ‘in-between’. There will be some ‘peripheral distortion’ around the edge of the lens but this will be minimal and most customers will adapt to them very quickly.

Premium varifocal:

Premium varifocal lenses, sometimes referred to as ‘free-form varifocals’ or ‘back-surfaced digital varifocal lenses’ are created using the latest computer driven equipment and have a wider field of vision at the distance, intermediate/in-between and reading focal points. This is because the lens is a customised varifocal lens and made to fit within the frame you have purchased. It is unique to your prescription and the lens shape of the frame you have chosen and therefore offers the fullest and widest vision possible with a smooth transition between the focal ranges. They have minimal peripheral distortion and are easy to adapt to.

Premium varifocal lenses offer much clearer vision at all points and are a significant step up from a standard varifocal lens in terms of vision, clarity, focus and ease of adapting to them.

Elite varifocal:

These varifocal lenses will have the widest field of vision at all focal points with much less distortion around the edges. They are tailor made varifocal lenses and customised and made to fit within the frame you have purchased. They are very easy to adapt to and again, free coatings may be included.

Lifestyle/Occupational varifocal:

These are specific to different lifestyle or occupation vision needs or for those who are constantly shifting their focus between distance, intermediate and reading and will provide a wider and clearer field of vision when looking ahead or into the distance. If you frequently perform tasks at arm’s length – like reading a book or using a tablet device – then you’d appreciate a broader, more comfortable near zone of vision to help you see the details.

The main differences & features are:

  • Larger distance viewing areas
  • Larger reading viewing areas
  • Wider field of vision, known as the ‘corridor’
  • Less peripheral distortion

Simply put, the more advanced varifocals have a wider field of vision with less peripheral distortion. They are often much easier to adapt to because of this. Typical speaking, the more you pay, the higher the specification of lens you get with improved vision.

How to choose varifocal lenses:

We advise selecting a frame with a large eye size – the bigger eye, the bigger the vision as you will have a wider field of view and fully benefit from the lens area – although all of our frames, small & large, are suitable to be bought with varifocal lenses.
