Dr. Wood (Ithaca, NY) is unusual in that he listens to his clients, and he tries to do what they want! I wanted two pairs of glasses set up with four different distances in each, and with non-standard placement of the bifocal insets. For normal use, I wanted my (predominant) right eye optimized for 20' in the main lens (one that is larger than normal), and with its flat-top inset lens the smallest available, set considerably lower than is normal (and with its straight-line top tilted properly to make it invisible), and optimized for 3.' For the left eye, I wanted optimization for the large lens to be for 6', with its inset lens set for 2'. With these, everything is in focus most of the time (although there may be a week or two of use needed at first to make these glasses work correctly). For the smaller-lensed close-work pair, I use the distances 2.5', 1.5', 2', and 1'. With both of these pairs of glasses, I can see sharply over a wide angle of view, both horizontally and vertically (including, with the distance pair, the ground and stairs, or food and the people opposite me, plus more distant things) easily. These are much better than "lineless" bifocal glasses (which are "mushy" away from the center area - I hated those!). Dr. Wood (at Cayuga Optical, Ithaca, NY) was willing to make these for me many years ago, and I have been happy with them ever since. C.O. is also very good about fixing or correcting glasses for free with ones that they have supplied. read more
