Individuals who use computers, particularly desktops, have particular visual needs. I had a patient who was prescribed a progressive lens for distance and near. He noticed that when he viewed the desktop, he wasn't able to view the screen comfortably. Since his computer was at about 22"-24" and he also had to view text at about 16", we prescribed him a bifocal with the top portion set for his computer distance and the bottom portion situated for 16". This worked out for him a lot better. What's important here is that the prescription is set for these distances. You would not be able to see clearly at far away with them.
