Whether or not you are a specs wearer you may have heard of a lens called a Varifocal. It goes by many names – progressive lenses, multifocals, PALS  (progressive addition lenses) or the world famous brand name of Varilux. They all refer to the same thing, a lens which blends together your distance, intermediate and reading prescription to give you back the sight of your youth.

This year marks the fiftieth anniversary of a lens which many customers think is some new fangled idea that will be difficult to wear and is expensive. History speaks for itself though, this is a tried and tested product which has made millions of lives easier, using technology which has constantly evolved.

The varifocal lens was launched in 1959, the first true innovation in optics for many years. These early lenses were hard to adapt to, but in 1972 the product made great leaps forward and the usable areas of the lens increased. As time went on the lenses were improved further by adapting the lens design for different prescriptions, and reducing the distortion on the edges of the lens that made it difficult to wear.

These lenses are now available for most prescriptions, in different materials to make them thinner and lighter, go dark in the sun, or for tinted sunglasses. They fit in most fashionable frames, and there are different lenses for specific jobs, hobbies and professions. If you need help for reading and distance, then varifocals are the state of the art solution. They’ve grown up at the age of fifty, along with the Baby Boomers who now use them to make the most of their busy lives.
