Occupational Office Lenses are designed specifically for near and intermediate distances for use generally in the office environment. These lenses offers an extremely wide near vision region using a very soft design that eliminates the swim effect and perceived lateral distortion. The prescription changes from the upper part of the lens to the lower part gradually, giving you the convenience of viewing objects further away or words up close as you shift your angle of vision.

There are two general categories of designs - lenses that have reading to mid-range vision or those with reading to distance. The design is actually progressive but the design significantly increases the size of the mid-range and reading power zone and removes or significantly reduces the size of any distance zone. The purpose of degressive lenses is first to correct near vision and intermediate vision with degressive power towards the top of the lens. Four fixed degressions are possible from 0.75, 1.25, 1.75 or 2.25 dioptre depending on the needs.
