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.
Desk top computer use is usually more demanding beginning in the late forties or early fifties. Viewing through the distance portion of your eyeglasses to see just beyond the reading range to the computer screen puts a strain on your eyes by overworking the eye’s accommodative/focusing ability. The amount of lens power necessary to relieve the eyes from the stress is about half the amount of power necessary for you to read with.
By taking these initial steps, you should be able to alleviate much of the pain or stiffness you may be experiencing. If you are still encountering pain, you may also want to investigate alternatives to the traditional computer desk chair. By placing your body in a different type of posture altogether, you may be able to reduce the strain that comes from sitting in a static position for long periods of time. Popular alternatives are sitting on an exercise ball, or dynamic stool, which forces you to use your abdominal muscles for support and helps reduce muscle fatigue.
