A varifocal is sometimes known as a progressive lens. There are no visible markings or segments separating the different vision areas, and the prescription gradually changes down the lens from distance at the top, through to intermediate and then to reading at the bottom. Many patients feel a certain amount of trepidation about trying varifocal’s, feeling perhaps they will not be able to adjust to them. A small proportion of patients may struggle to adapt, but the vast majority enjoy great benefits from varifocal’s. we offer all our patients the assurance of a 60 day period to decide whether varifocals are right for them. If not we guarantee to provide you with an alternative, be it single vision, or bifocals.
Bifocals have the distance power at the top and a reading power in the lower segment of the lens. There are visible markings separating the areas.
Single vision lenses have one power only, either distance or reading, although it is also common for patients to have an intermediate lens too, for computer work etc.
These lenses are popular and darken on exposure to UV light. Generally darkening to a brown or grey colour.
