Single vision Lenses
A single vision lens is described as such simply
because it contains one
prescription in the lens. This prescription is typical
used for distance, intermediate (for example when
looking a computer screen) or reading. You may need to
wear a distance prescription most of the time if you are
long or short sighted, or have an Astigmatism. If you
need to wear glasses to read or to see objects close up,
then single vision lenses can be used, however you will
most probably be unable to see objects sharply at a
distance further than arms length. If you require
glasses for reading, then it may well be worth
considering a Bifocal or Varifocal lens.
Bifocal lenses, as the name suggests, allows two
different prescriptions to be incorporated into one
lens. Bifocals are typically used to provide both
distance and near prescriptions. This is achieved using a small segment,
usually in the lower portion of the lens, which the
wearer looks down through in order to read. Originally invented by Benjamin Franklin in
1760, the Bifocal has been the most commonly used multifocal lens up until recent times. Now varifocal
lenses can allow wearers to eliminate the visible
segment and have more flexibility with their vision.
Varifocal lenses are now the most commonly type of
multifocal lens used today. Varifocals work in a very
similar way to a bifocal lens, by allowing the wearer to
look through the lower portion of the lens to read.
However varifocal lenses use a gradual transition of
power from distance to near. Not only does this
eliminate any visible segment, it allows the
wearer to gain an intermediate prescription between the
distance and near portions of the lens. This means you
look into the distance, for example when
see sharply at an intermediate distance, for
example when looking at a computer screen.
see sharply at near or reading distances.
put, varifocal lenses can suit every aspect of day to
day spectacle wearing.
Varifocal lens design has improved dramatically over the
years. The technology used to generate the complex
curves has made leaps and bounds, to improve wearer
comfort and increase visual performance. Freeform
technology has meant that varifocals can now be custom
made to your prescription, almost eliminating adaption
time, and offering an option for patients who have
struggled with varifocals in the past.
Our varifocal lens of choice is the Wideview Zenix
from Jai Kudo, a freeform varifocal and one of the
best performing lenses we sell. We can also use varifocals from some of the other major
manufacturers such as Seiko and Essilor.

All of our lenses come with the option of an
anti-reflection coating or MAR. This is a coating that reduces reflections on the surface of the lens.
The two main benefits of this are an improved cosmetic
look and a reduction in glare from bright lights. This
is very useful in low light conditions such as night
driving, where the 'starburst' glare from headlights can
make driving difficult.
We can also offer Hydrophobic coatings on many of our
lenses. This acts as a 'non-stick' layer for grease,
dust and dirt making cleaning your lenses much
