Which is the right lens for you?
This depends on many factors. Optometrists and Dispensing Opticians are experts in being able to assess your visual and frame requirements and advise you on the options available. There are many different lens designs, from many different lens manufacturers.
Single vision lenses are the simplest form of lens design. They can be used as general all-purpose lenses, or for more specific visual tasks.
Enhanced readers, sometimes called workplace or occupational lenses, are designed to offer a greater range of focus than traditional single vision lenses. These lenses are particularly well suited to people over 50 years old who want to be able to focus on computer screens or sheet music as well as normal closer reading all in one pair ... no compromise!
Bifocals are lenses that allow people over about 45 years old (presbyopes) to focus on distance vision and near vision with one pair of glasses. It is often a more convenient option than carrying two separate pairs, although the design of the lenses can have limitations in certain situations. All bifocals have a visible line somewhere on the lens that marks the transition between the distance part of the lens and the reading segment. Most people find that bifocals are not particularly easy to use when looking at computer screens and other middle distance objects.
Varifocal Lenses (Progressive Lenses)
Varifocals, or progressive lenses, like bifocals, replace the need for presbyopes to keep swapping glasses. These lenses allow clear focussing at all distances from far away objects through to near objects in a smooth and progressive transition within the lens design. They are ideally suited to be worn as everyday general purpose lenses with the convenience of being able to get on with your day to day tasks without the need to keep swapping glasses for different jobs.
Our new Zeiss VISUFIT 1000 offers an unrivalled customer experience with ultimate accuracy
We are delighted to be one of the first optical practices in the country to adopt this latest technology into our dispensing area. All spectacle lenses perform best when they are aligned properly with the eyes, but this is particularly true for varifocal lenses. One of the commonest causes of problems with varifocals is the centration of the lenses to the eyes. If this has not been set up correctly then the visual comfort and performance of the lenses can suffer significantly.
