was trying my luck la....even bifocal is not tat common too
bifocals are actually quite common, among the elderly.
most could not get used to progressives, and don't use computers don't care about aesthetics (there's a blended type if they care)
as an option for those who drag their feet before getting glasses for presbyopia, bifocals are a much safer choice since the line is very visible making it easier for the elderly to adapt.
most of the time when you go to the local opticians the optiions given would be progressives, (more indices to choose from, more common, easier to sell, better profit.)
but if you were to encounter older opticians especially those with their own practices and er..think that the customer may not be able to adapt, you'll often get the suggestion that you try out bifocals, then move on to progressives.
others ask you to try reading glasses first , then bifocals then progressives. or reading then progressives.
personally , if you haven't worn glasses by 60, and you have that slow mo thing going on with old folks. best not to fit progressives on the first try.
either 2 pairs to switch or bifocals. and if you feel adventurous after 6 mths and all goes well, then maybe progressives.
older folks don't adapt well to new stuff(if you don't get a good pair of progressives, they generally restrict your field of vision, for both near and far. which is why bifocals still have their hardcore fans)
will probably take another 20-30 years for the current generation to move on before bifocals die out.
but some labs like essilor actually sell bfocals as children's myopia control lenses and asserts it works better then their progressive like design.
