Being independent opticians means we are not tied in to a particular lens supplier and we are able to source the latest hi tech lenses for you from either an international lens company like Essilor (who invented the varifocal lens), Hoya, Zeiss and Kodak or from one of our smaller bespoke manufacturers who work closely with us to produce special one off products.
Whatever your requirements are we are always happy to find the ideal solution to fit in with your everyday lifestyle, sporting or social needs.

Common types of lenses
Single Vision Lenses
A single vision lens is made using either your near or distance vision prescription. As such if you need to, you may end up with two pairs of glasses, one for reading and close work, and a second for distance, everyday things and driving. We can also supply prescription lenses to meet your personal needs. Requirements such as lenses for computer use, for using smartphones and tablets or for detailed close work such as needlework or painting can all be accomodated.
Bifocal lenses are manufactured with two prescriptions lenses. Your distance lens is at the top, and your near vision lens at the bottom, so you can simply glance down for reading and close work. Bifocals have a visible line across your lenses.
Varifocal lenses have a gradual change in lens strength from the top of the lens to the bottom. Unlike bifocals, varifocal glasses have no specific area of lens strength, but progressive lens zones. This means you can simply glance down to read, and the lack of a dividing line make them visually more appealing. They can remove the need for multiple pairs of glasses.
