What Are Occupational Lenses?
An occupational lens is a design in prescription eyewear that allows the wearer to view all working distances, side to side, up and down, within a conventional working distance, or small environment. A working distance typical to many occupations will fall somewhere between ten to thirteen feet, respectively.
Our working and lifestyle environments require that we have clear vision at working distances of 1.5, 2.5 and out to 10 feet. And, this vision must be clear in all areas of the lens, at all viewing angles.
The problem is, presbyopes (bifocal/progressive addition lens wearers) have had limited options for mid and near range visual requirements. The solution to this unique visual requirement based on occupational/visual needs is a variable occupational lens. It is the best optical solution.
According to USA Today...
More than 100 million people use computers (a statistic from 1998…it is likely much higher today…)
Ergonomics play a large role in our ability to work comfortably, without causing neck and back strain at the end of the day. For best comfort, we should be plane with our computer station, or balanced, in essence. This requires that we are able to sit up straight in a chair, view our computer monitor below our line of sight, at a comfortable viewing angle. All the while, we need to be able to relax our wrists and forearms while typing, and maintain focus on the ever-changing computer monitor pixels with varying contrasts.
Quite a challenge!
The Solution: Occupational Lenses
Different than a progressive addition lens, this variable design begins with the full reading prescription at the bottom of the lens, and weakens, for mid-range vision, as the eyes rotate upward. Almost like an upside down progressive – taking away power vs. adding power.
In the middle of the lens, the entire design is devoted to intermediate vision. The Shamir Office Occupational Lens is the only design to take this approach. Then, the other portion of the prescribed reading power is reduced as it reaches the upper part of the lens. This unique design approach brings quality optics from 10 – 12 feet distance, tapering in to normal reading distances, around 16 inches, or 40 centimeters. If your lens is working for you, you can give your neck and back a break.
You will not need to tilt your head in order to find the best optical zone in the lens…it is designed to match visual requirement with ergonomics.
Comfortable vision and good working ergonomics are too important to leave to chance. Choosing an occupational lens, specifically designed for small environments with adapting optics is the best optical solution for clear vision at varying focal ranges. Choose the Shamir Office occupational lens… your eyes and back will thank you!
