What activities do I want to wear my glasses for?
If you need a spectacle prescription then, depending on your age, there is a choice to be made whether you wear glasses for all activities (varifocal lenses), most activities (bifocal lenses) or a single activity (Single Vision lenses). If you are under 45 typically you will be able to wear a pair of single vision lenses and your eyes will automatically adjust in order to view an object at any distance.
 
Single Vision lenses
Are manufactured with a single prescription in them. For short sighted (myopic) people they will enable you to see in the distance and typically the lens of the eye is able to adjust to see close up objects. For those who have problems with reading or seeing a computer screen single vision lenses will solve this problem, however they can lead to objects in the far distance being blurred.
 
Bifocal Lenses
Have a prescription for reading in the bottom and a different prescription for the long distance in the upper portion. With a distinct line between long distance and reading they can provide excellent vision for these distances but are cosmetically not as attractive and sometimes people feel that there is an intermediate distance which is not clear through the glasses.
 
Varifocal Lenses
Are also known as Progressive lenses as they change prescription gradually from long distance in the top through an intermediate power to a reading power at the bottom. Originally designed over 40 years ago the quality of vision achieved has got better and better providing wider reading and distance sections than ever before. These lenses have now developed even further with the benefit of new manufacturing techniques enabling a whole new generation of bespoke lenses to be designed and supplied. These lenses are designed individually and made to your specific prescription, sometimes taking into your facial characteristics and that of the frame to ensure that you are receiving the highest quality in design.
 
All round vision
Unlike the bifocal there is no line separating the prescriptions so they are cosmetically more attractive, and are the lens of choice for today's more demanding spectacle wearer. There are many different designs in varifocal which vary in what they provide. The most widely worn and best known are Varilux lenses manufactured by Essilor, who invented the Varifocal lens.
 
How do I want my glasses to look?
Probably the greatest advances in lens design over the last few years have been in this area. With the majority of new lenses being manufactured from plastic materials modern lenses can be flatter, thinner and lighter than ever before; meaning that they know look and feel even better than ever.
 
Thinner and lighter lenses
By using different materials with a higher refractive index a lens can be manufactured so that it is thinner at the edges. This means that even people with very high prescriptions are able to have lenses which are cosmetically more appealing as well as more comfortable to wear as they are lighter. With different materials offering alternative thickness' you can save up to 50% off the thickness of your lenses.
 
Flatter lenses
Can be manufactured for long sighted (hypermetropic) people whose spectacle lenses can often be quite thick and bulbous at the centre of the lens. By using an aspheric design to the lens it can be manufactured much flatter and thinner than normal. By combining this design with different materials the lens can provide you with a superbly flat and lightweight lens up to 35% flatter and lighter.
 
Anti-reflection coatings
Are the ideal coatings for any one who drives at night, uses a computer or just wants to look great. By letting more light through the lens the coating cuts out many of the day to day problems people experience with lenses whether it be dazzle from car headlights or glare for reflections on a VDU screen. Combining it with a scratch resistant, anti smudge and anti static coatings means that your lenses benefit at the same time as you. Watch the video to understand how these coatings can really make all the difference to your vision.
 
Photochromic lenses - Healthy and safe

Available in lightweight plastic the most modern of these lenses, Transitions, will also absorb harmful rays of both UVA and UVB light to give your eyes maximum protection. The latest plastic Transitions is the fastest reacting ever, goes the darkest when reacted and is available in a choice of thinner materials.
