The difference between using some magnification for the computer distance while in your late forties and older, versus not is demonstrated with this simplified example. Given a choice, would you rather walk two miles to work or ride a bike the two miles? You’ll get there either way, but you will spend a lot less energy using the bicycle. This is the reasoning and science behind using a dedicated pair of computer glasses or using a computer clipon lens.
The secretary desk is one of the longest desks that have been in use over the centuries. Before there were any electronic gadgets that would handle of the secretaries tasks with the click of button, a secretary would handle all the operations for their employer and would use this desk to their job.

Working at a desk top computer over fifty years of age with your general purpose prescription eyeglasses can be challenging on your eyes. The eye’s focusing ability is under a strain to keep the content on the screen clear. Just because you can see the computer screen clearly through the distant portion of your glasses doesn’t mean you are not taxing the eye’s focusing ability to maintain a sharp focus. Also, lifting your chin up to see through the mid portion of your progressive style lenses will have consequences on your neck and back due to poor ergonomics. The reason you are using a bifocal is to see at close reading distance clearly for extended periods of time.
