Over the last couple of years many new developments in spectacle lens technology have evolved such as
thinner, lighter lenses, special lens coatings, and new types of light sensitive lenses that have all been
designed to improve your vision and ensure that your spectacles are more comfortable to wear.

At Bethell & Clark Opticians we are free to choose from one of the wide selections of quality spectacle lenses, offering brand names such as Seiko, Varilux, Zeiss, Hoya and Tranitions to name but a few. This means we can offer a wider choice together with a personal Service that caters for your particular requirements, lifestyle and budget.

If you have trouble focusing both close up and far away, you are probably familiar with bifocals or
trifocals. These lenses have different segments for reading and distance and some people dislike them for
cosmetic reasons, or find that the dividing lines detract from visual comfort. If this applies to you the
answer could be 'bifocals without lines', these are also known as progressive or Varifocal lenses. These
lenses progress gradually from a distance strength at the top to a reading strength at the bottom, giving a
range of focusing strengths in between. There can be some blurring with peripheral vision, but we are
finding that this type of lens is becoming increasingly popular as people discover the more natural
correction they offer.

Lens reflections can be a problem for spectacle wearers.

There are four different types of reflection:
Reflections on the front of the lens, seen by other people.
Reflections from behind which are superimposed on the wearer's field of vision.
Internal reflections caused by lens thickness, particularly noticeable in high-powered lenses.
Reflections at the front surface of the eye.

All these reflections can reduce the amount of light reaching the eye by, as much as 15%, which means
both vision quality and contrast are impaired. There is a solution. By treating the lens with special layers
of coating, reflections can be limited to less than 1% and the problems are almost eliminated.

Because anti-reflection lenses give such a dramatic reduction of reflections, the benefits are significant.

Clearer and sharper clarity of vision.
Closer to natural vision.
Improved driving vision - especially at night.
Less VDU glare.

In short, everyone who wears spectacles will enjoy the overall improved visual comfort provided by anti
reflection coatings.

It is advisable to wash your spectacles regularly in warm soapy water to discard skin acids, dust and grease.
Afterwards carefully dry and polish the lenses with a soft clean cloth (we offer a range of inexpensive
cleaning solutions and cloths suitable for all types of spectacles and contact lenses conveniently packaged
for everyday use).

Whenever it is necessary, our qualified dispensing opticians will be pleased to adjust your spectacles to
ensure they are comfortable and provide you with the best possible vision. Minor repairs such as refitting
lost screws, can usually be done while you wait, so please call in if you experience any difficulties.
