Single vision lenses are used by those needing a correction for general distance or close up work. Single vision, as the terms suggests, assist us to focus at one distance only and would be used, for example, when driving or when reading. Spectacle wearers up to the age of 40 can generally manage with single vision lenses as any extra help required for reading is automatically catered for by the eye adjusting its own power.
Bifocal lenses are effectively two lens powers combined together to assist with both near and distance vision. The most common use of bifocals is for reading correction in the lower lens together with a modest distance correction in the upper lens, giving sharp vision at two distinct distances. Bifocals can also be supplied with a clear (upper) lens for those requiring reading glasses but not wanting the inconvenience of removing their spectacles every time they look up.

They offer a gradual transition from distance vision at the top of the lens to reading towards the bottom.Varifocals are increasingly being chosen as an alternative to bifocals - they have better cosmetic appearance and a more versatile range of focus
