Best Posture for Reading With PAL lenses the best area for reading is found in the lower area of the lens. To optimise your near  Vision you need to position reading material about 40° below the horizontal line of vision as shown in this figure:- The lateral field of view is not as wide as found in single vision reading glasses. Accordingly you may need to move your head a little to take in the full width of the page. Progressive lenses offer a more natural visual experience. Unlike single vision designs PALs give you a continuous range of focus- from up close to far away.

Standard Progressive	Freedom Progressive

Progressive Addition Lens (PAL) is the most popular choice for people seeking help with their reading vision. PALs work by channeling the focus to a strong zone in the lower part of the lenses. They are also referred to as ‘Multifocal’ lenses.

Progressive lens focal zones

Q What are the disadvantages of my existing conventional Progressives?
A  Despite the enormous popularity of standard progressive glasses they do have some serious limitations. Enjoyment of wearing multifocal spectacles has been limited by narrow fields of view. Other wearers experienced distorted vision and a swimming sensation when looking through the peripheral part of their glasses

Image Distortion Caused by  Standard PAL

These problems have been mostly overcome with application of WAVEFRONT TECHNOLOGY to Multifocal/ Progressive spectacles. 

Q What is Wave front Technology and how does it work?
A  Wave front lenses work by controlling image distortion. When light passes through any optical system including; spectacles, cameras, Binoculars, and even our own eyes, the image formed is always slightly imperfect or distorted.  Wave front Technology calculates the path taken by light as it passes through many different points on the optical surface of your glasses.
 Using some complex maths a computer generated surface is then designed for your individual prescription and lens type. This surface cancels out unwanted aberration. It is combined with your spectacle lenses to give you unprecedented levels of optical clarity.
