    I have had the most consistent success with the Essilor Computer Lens. The unity Via OfficePro is doing well for me, too.

    We have used the Shamir and Unity lenses without any problems.

    How do you fit the Essilor Computer Lens?

    You fit it with distance PD and standard PAL seg height. The centration chart is weird; do not mark it up like a standard 4 drop progressive, as the OC is also offset horizontally. The lens also requires a minimum 15mm between the OC and the top of lens to keep the "room view" distance RX sliver, but that's more of a bonus feature than a requirement. The lens works without it, just make sure the patient knows that they're losing it by choosing a frame with too low a B measurement. The biggest problem I have with the lens is that it's only available in poly, so higher RX patients are out of luck.

    I don't work with VSP and the line of UNITY© products, but I second the Shamir lenses. Shamir's Computer or Workspace are my go-to near variable focus option, and I also do a little with Hoya's iD Space/Screen/Zoom lenses (the Zoom works well for a dedicated laptop user or for a close working distance). If you work with a lab that offers IOT lenses, their office lenses (they can be ordered with focal lengths up to 4, 6.5, 13 or 19.5 feet) have also worked really well for me.

    Shamir's Computer and Workspace designs have different focal lengths. Per Shamir, the Computer design is a compensated design with a focal distance up to 5 feet, better for patients that live in front of the computer. The Workspace design is compensated for up to a 10-foot working distance, better for patients that need to look up at clients entering an office, etc.

    If it is strictly a computer PAL and the patient doesn't need to see beyond the screen for anything, I always make them from a standard PAL with Rx adjustments. Usually reduce the add by half and add it to the distance Rx. This can be changed by a .25 for closer or further screen distance. This give them full width of the lens for screen(especially useful for multiple monitors), and still gives them full near for pickup up papers or phones/tablets. These type of lenses are for people who spend the major part of their work day in front of a screen, maybe in a cubicle, and don't need to get up frequently.

    If you have someone who is a heavy computer user, but also needs to get up frequently for meetings or needs to see across the room, then you want a degressive designed "office" lens. Built with the correct amount of degression for their needs. Throw a dart at the board and pick your preferred brand. I prefer IOT lenses myself.

    I have used Shamir Office and Computer, but not Workspace. What is the real difference between WORKSPACE and OFFICE ?

    To be clear- leave 15mm to the top of the edged lens.

    Hoya Workstyle Zoom and Screen are fantastic. I've also used Hoya Sync 3 0.57 with great results for those people whose computer screen is very high up and close.
