Coronavirus Update


In recent years, and continuing to this day, there have been major developments in the world of spectacle lens technology, all with the intention of wanting to enhance your vision and make your experience of wearing spectacles as successful as possible.

There are many spectacle lens options out there and sometimes the choice can be rather overwhelming. However, here at John Weygang Optometrists LLP we have an experienced team who are happy to discuss and advise on the most suitable spectacle lens option required to fulfil your individual lifestyle and vision requirements. We are here to help guide you through this process, using our expertise to make it as stress-free as possible so that you end up with the correct choice for your needs and also within your budget.

We are able to cater for any spectacle prescription and using our trusted lens suppliers and manufacturers we can provide all of the following spectacle lens options:

  • Single Vision

This refers to a spectacle lens that only provides for one spectacle prescription. If you have need of more than one spectacle prescription (e.g. a distance prescription and a near prescription) then this would essentially mean separate pairs of spectacles to swap between.

  • Bifocal

A bifocal is a spectacle lens in which there are two distinct portions on the lens, each providing for a different spectacle prescription. The most common setup for a bifocal is to have the main portion of the lens providing the distance prescription and then the smaller portion (i.e. the segment) that is located towards the bottom of the lens providing the near prescription. However, this can be adapted depending on the needs of the person. Obviously a bifocal is only applicable to those people who have need of more than one spectacle prescription and although they do take some getting used to, they overcome the issue of having to swap between separate pairs of spectacles.

  • Varifocal

A varifocal is a spectacle lens that is designed to provide continuous clear vision at all distances and so is more flexible than a bifocal in that sense. As you look down through the lens, the power gradually increases. This means that for whatever task you are doing there will be a point on the lens that corresponds to that working distance. It is then just a case of finding that point on the lens by adjusting your head up and down accordingly. The only downside of a varifocal is that because of the way they are made you end up with areas of soft focus or distortion at the edges of the lens. This means that when you look off to each side it will not be as clear as it is when looking straight ahead, hence why a person wearing a varifocal has to learn to look at things more with their nose. Obviously a varifocal is only applicable to those people who have need of more than one spectacle prescription and although they do take some getting used to, they overcome the issue of having to swap between separate pairs of spectacles.

  • High Index

If a person has a high spectacle prescription, this can increase the thickness and weight of their spectacle lenses if they are glazed using the standard lens material. In these circumstances, it would always be preferable to use a higher index lens material instead. This has the benefit of making the spectacle lenses thinner and lighter whilst maintaining their refractive properties. The result of this is that it makes the spectacles look better and also makes them much more comfortable for the person in question to wear.


All of our spectacle lenses have a scratch-resistant finish incorporated as standard. In addition to this, we are also able to provide an anti-reflection finish. The purpose of the anti-reflection finish is to reduce the effect of glare (i.e. from the headlights of oncoming vehicles when driving at night or from a mobile phone, tablet or computer screen) as well as optically make the spectacles lenses look clearer. More recent advances in spectacle lens technology have taken this one step further, allowing for an anti-reflection finish that, in addition to being scratch-resistant, has the added benefit of making the spectacle lenses water-, dust-, grease- and dirt-repellent. As a result, this makes the spectacle lenses more durable and much easier to clean and you will be pleased to know that here at John Weygang Optometrists LLP we can provide this finish on your spectacle lenses as well.
