Hi. I am far-sighted and have add +2.25DS.  I’m currently using 2 eyeglasses: 1 bifocal for reading and 1 with full grade lens for computer use. I use the computer almost the whole day at work. Problem is, I switch from one eyeglass to another when I have to get up from my desk because with the computer glasses, everything is blurred beyond an arm’s length. My optician has recommended progressive. But would this solve my problem, can I use the progressive for computer work?  I understand it’s the lower part of the lens that I would need for computer-distance.  Would that not strain my neck as I would have to tilt my head to use that part?  I’m supposed to buy the glasses in 2 days, so I would appreciate your advice. Thanks.

Hi Ruby,
Progressives would solve your problem as they actually have three different powers – distance, intermediate and near.  All distances will be clear with these lenses.  There is a different prescription for the computer than there is for reading.  With progressive lenses the top part of the lens is for distance, and then it gradually changes into an intermediate prescription and then into reading at the bottom of the lens.  The intermediate portion is part way down the lens.  Therefore to look at the computer screen you will have to look slightly down, but not all the way to the bottom of the lens.  You do need your computer monitor in the right position for progressive lenses to work optimally.  Ideally you want the top of the monitor to be at about eye level, that way you are naturally looking down at the monitor.  If your monitor is too high you will be forced to tilt your head up.  The only thing you may notice in going from a strict computer lens to progressives is that the clear area will be narrower and in one spot, versus the computer lenses, which allow clear vision for the computer through any part of the lens.
