Left Picture: Show the vision with distortion on the sides of the outdated technology lens, which selling in most stores worldwide.

 

Centre Picture: Show the wider vision and lesser distortion of the Single lens technology, “Aspheric”, which selling in many stores around the world.

 

Right Picture: Show the widest vision and least distortion by the Hi-End technology single lens, which is standard quality from ISOPTIK.

Hi Bobbie,

about aspheric lens, is there any difference between front aspheric

(which is the most common one) and the back aspheric lens ?

Or all the semi-finished lens are called front aspheric ?

Or the back aspheric called free-form S/V ?

Hi Wilson,

  1. The most of Semi-Finished Aspheric lenses and Finished Aspheric lense are front surface aspheric.
  2. Free Form Aspheric can produce in back side or double sided.
