Spectacle Lenses

As an independent optician, we are free to select the best lenses from any manufacturer.  This means we can offer you the widest choice, together with a personal service that caters for your particular requirements, lifestyle and budget.

When you visit our practice we will discuss your needs and advise you of the best options, without obligation.  In the meantime, this page outlines some of the main points to consider when choosing your lenses.


Anti-Reflection Coating
An anti-reflection coating has several advantages.

First, your vision will be better as more light is allowed to pass through the lens; this is especially effective when driving at night as it significantly reduces headlight glare.

Second, as there are no reflections on the lens surface, people can see your eyes more clearly resulting in a much nicer looking finish.

Third, the coating has a scratch-resistant layer meaning the lens is harder to scratch.

Fourth, for shortsighted people, it reduces the rings or “time warp effect” seen at the edge of the lens.

The only real disadvantage of the anti-reflection coating is that because it’s clearer, it shows smudge marks more.

UV Protective
Excessive exposure to the sun’s ultra violet rays is harmful to your eyes and can contribute to conditions like cataract and AMD.  A UV filter on your lenses reduces the amount of UV light entering your eyes and reduces the risk of damage. It can be combined with an anti-reflection coating or done as a stand-alone treatment.

Forté Coating
Most lenses can be given a Forté coating which has all the advantages of the anti-reflection coating and UV coating as well as being smudge-resistant and guaranteed against scratching for two years.

Blue Coating
A blue coating is designed for people who use a lot of electronic devices, which in the modern world is becoming more and more common.  All these devices give off a large amount of blue light that over-stimulates our eyes, causing eye fatigue and insomnia. A blue coating reduces the amount of blue light passing through the lens, thus reducing the effects.

Thinner Light-Weight Lenses
Hi-Index materials mean that we can make your lenses thinner, lighter and better-looking.  This is great if you have a high prescription, as it improves the look of your glasses and allows for a wider choice of frames.

Light-Sensitive Lenses
If you’re sensitive to bright light or don’t want to switch between spectacles and sunglasses then photochromic lenses are ideal.  These lenses darken according to the amount of UV light.  They go from virtually clear to very dark in a matter of seconds and the latest generation change back to clear in about a minute.  Almost all lens designs are available in a photochromic.

Lens Designs

Single Vision
This is the standard lens design which has the same prescription throughout the lens – this is what we use for most single-purpose glasses, such as reading glasses.

If you require both near and distance vision correction then you are probably presbyopic: a natural condition which nearly all people will experience from their mid-forties onwards.

One solution is to have separate pairs of glasses for distance and reading, however this can be inconvenient.  Varifocals have seamless transition from distance in the upper half of the lens through intermediate distance to reading at the bottom. They are much better-looking than their forerunner, the bifocal, as they have no visible change between prescriptions. They’re more convenient than separate pairs, especially in every-day life where we need to switch between near and far vision frequently.

The major drawback of the varifocal lens is the small areas of distortion you get in the peripheral vision, though the most recent and advanced designs have virtually no distortion.

Occupational or Computer Lenses
These lenses are designed for people who spend a lot of time on computers.  They are much like varifocals in that they have multiple powers through the lens, but typically they dispense entirely with the distance portion and focus on the intermediate, which is the computer part, and go into reading at the bottom of the lens.  Combined with the blue coating mentioned before they make using a computer much less tiring and greatly reduce eyestrain.

Under European legislation you could be entitled to an eye test and computer glasses paid for by your employer.

These are the older type of lens for people who are presbyopic.  Like varifocals they provide both distance and near correction but they have no gradual change from one to the other, instead having an obvious dividing line to the reading segment at the bottom of the lens.
