Varifocals And Their Uses
Varifocals also called the progressive lens are smooth in appearance with three different prescription zones. Look through the top you’ll see distance objects, through the middle for intermediate and the bottom of the lens for reading.
The experience is progressive as your eye moves up and down the lens. Like a camera lens with variable focal length in which focus changes as focal length and magnification changes.
The lenses in Varifocals allows you to see objects at varying distances giving you back your natural vision and help you to see the way you used too.
Who Wears Progressive Lenses
Varifocals known as Progressive Lenses arepopular among people aged 40 and above who live an active lifestyle and require three prescriptions but only want to own one pair of glasses. The varifocal lens is generally more expensive than that of say a bifocal lens, partly due to the complexity involved in its manufacture even though it’s been commercially available since 1922.
Advanced lens manufacturing has seen a number of different types of varifocal lens arrive in the market place. Each supplier attempting to seek perfection as they explore new combinations of materials and methods that may enhance production.
Some well established brands clinically test their lenses and provide a guarantee or certificate of authenticity which describes the lens’s characteristics and prescription, a point perhaps worth considering before purchasing Varifocals.
Several suppliers name their lenses in a bid to clarify exactly what the lens has to offer, one example could be the field of vision, another might be for reading especially in poor light. Varifocals do a similar job but in a different way.
A Varifocal or Bifocal Lens
Varifocals have three prescription zones whereas the bifocal has two leaving out the intermediate. It is not uncommon for a bifocal wearer to experience headaches and even dizziness in some cases. One reason being the small field of view offered by the reading segment of bifocals which can take time adjust. One solution is for the wearer to learn to move their head or the reading material rather than the eyes.
The introduction of computer monitors placed directly in front of user can lead to muscle fatigue due to the unusual straight and constant movement of the head. This might be reduced by the use of trifocal lenses or specific office lens designed for computer use.
