    Smilie Progressive or Bifocal?

    In terms of getting the clearest vision, would you suggest a person who wants computer glasses go with progressives or bifocals (intermediate for computer plus reading)?

    The patient is currently wearing Panamics but with new stronger prescription, has a need for computer glasses now.

    Thanks for opinions.

    That gives me the run down on progressive choices but you don't say whether you think regular "old" bifocals would give the patient the best optics. In my opinion I think the bifocals would give a computer user the best, uncompromised optics in the computer range and then reading for the lower bifocal area.

    I wanted to get opinions from others before stating my own.

    Thanks!

    What does this patient do for a living? Is there a lot of paperwork lined up around the computer that needs to be seen? Is there a need for extreme focusing on gauges, graphs, data in small format? Sometimes I do recommend a D-35 or wider set high. Otherwise for a normal desk area a Physio is a good choice. Some patients dispite my best recommendations would rather use a progressive because of cosmetics.

    In my opinion, the answer to your question depends on how many computers he uses. If he sits at work 20 inches from the screen, then goes home to use his laptop at a 25 inch distance, the bifocals won't work as well. If his work distance is always the same, then I'd agree the widest, sharpest vision is from a bifocal.

    FT bifocals if the person is on the computer 8 hours a day . Add a slight tint if you wish and preferably a good A/R coating. Why Ft bifocals ...because there is no head tilt strain ...simply raise the eyes to focus on the screen.

    Suggest two pairs, one for the work place and one to leave at the computer at home.

    Be sure of the working distances . :cheers:

    No doubt, the segmented multifocals will have a larger more defined field of vision at near. However, the add for reading is probably going to be in the +.75 to +1.25 range, offering a significantly larger near zone than the dress glasses, assuming they are about +2.25 or so. This also improves the field of clear vision on the distance part of the lens, making the lens less dynamic. Moreover, clients who wear PALs in their dress eyewear seem to prefer not to have a line on the computer glasses, myself included.

    So, although segmented multifocals have a slight advantage visually, the line can be disruptive for those accustomed to PALs, usually outweighing any optical advantages.
