Varifocals or Bifocals
PB could not use the varifocals he had been supplied elsewhere for his computers due to a limited intermediate area in his spectacles. Barbara tested his eyes and explained the choices available to him.
The choices were more varifocals which have a wider intermediate area, or office spectacles which are like varifocals but are focussed mainly for near and intermediate or bifocals which are also focussed for intermediate and near but have a more delineated segment.
He decided which he preferred and Barbara supplied bifocals with intermediate in the top and reading in the bottom.
PB was happy to remove them when he walked around the office and was satisfied with his selection as he obtained a larger working field of vision with his spectacles.
