Children's Eye Examinations
About 10% of children have some kind of minor eye defect and it is vital to correct these problems as early as possible. We recommend your child’s eyes are examined before school age and yearly after that. In addition to the large range of plastic & metal frames, which are covered by the NHS Vouchers, we have various fun children’s frames including the hugely popular Hanna Montana, Barbie and Batman, style frames. We also stock children’s frames by Bench, Pineapple, Whizz Kids, Icy and Lazer Junior.
Lens Types Explained
Everybody’s eyesight is different and whatever your prescription and visual requirements we have the experience to prescribe the correct lenses for you. Below is a brief explanation of some of the lenses available.
Single-Vision Lenses
The simplest form of spectacle or contact lens is the single-vision lens, made to a single prescription to correct a particular eyesight problem.Essentially distance or reading lenses. Concave lenses are used to correct short sight and convex lenses to correct long sight.
Concave lenses are generally thinner in the centre than they are at the edge and convex lenses are usually thinner at the edge than at the centre. The curvature of the lens, its thickness and weight will depend on the amount of long or short sight it is designed to correct. The lens material will also influence the thickness and weight of your lenses, as will the size and shape of the spectacle frame you choose. Our dispensing opticians will offer advice and guidance to help you choose.
Traditionally, spectacle lenses were made of glass but most lenses are now lightweight plastic and there is a wide range of materials available to suit your prescription and lifestyle.
Bifocals
Bifocal lenses contain two optical corrections with a distinct dividing line between the two parts. The most common use of bifocals is for people who have become presbyopic and need a different prescription for close work.
The upper part of the lens corrects distance vision and the lower half is for near vision. Trifocals are also available that have three sections and incorporate a correction for intermediate vision. Bifocals and trifocals come in a range of designs but nowadays varifocal lenses are much more likely to be prescribed.
Varifocal or progressive lenses
Varifocal lenses, also known as progressive lenses, are used for correcting presbyopia but unlike bifocal lenses have no visible dividing lines between the different corrections. Instead they have a graduated section in which the power of the lens progresses smoothly from one prescription to the other, allowing the wearer to see clearly at all distances.
These lenses also have the benefit of looking better – they don’t draw attention to the ageing process. A range of varifocal designs is available depending on your lifestyle and occupation. Modern lens technology means that there are many different designs and materials to choose from. Your dispensing optician will be able to advise you on the best lenses to suit your individual requirements.
We can also offer lifestyle lenses which are designed for specific tasks such as desk work.
High-index and aspheric lenses
If you need high-powered lenses you can improve the weight or appearance of your glasses with special lens materials and designs. High-index materials and aspheric designs mean that lenses can now be made thinner, lighter and better looking than traditional lens types. High-index materials make lenses both thinner and lighter.
Prescription sunglasses
We have a great range of sunglasses available, all new for 2011. We can provide sunglasses for distance, reading, bifocals and varifocals. We can even provide non prescription sunglasses if you are lucky enough not to need a prescription or to wear over your contact lenses.
Anti-reflection coating
Spectacle lenses can be provided with anti-reflection coatings which virtually eliminate distracting reflections off the lens surfaces. Reducing reflected light is particularly helpful for computer users and for night driving. Anti-reflection coatings also improve the cosmetic appearance of your glasses highlighting your eyes not the spectacle lenses.
Scratch-resistant / hard coating
Plastic lenses are lighter than traditional glass lenses but they scratch more easily. Scratched lenses can be irritating for the wearer and look unsightly. Scratch-resistant coatings are available to protect against damage and prolong lens life.
Multi-coated lenses
Multi-coated lenses uncorporate a combination of coatings – anti-reflection, scratch-resistant, water repellent and UV. All our anti-reflection coated lenses have a multi coating and all most thinner lenses are supplied as standard with a multi-coating.
Photochromic Lenses
All lens types are available in a Photochromic material. (Photochromic means to change colour with the light.) These lenses are virtually clear indoors and darken with light to turn into sunglasses on sunny days.
