I have a hyperope who was quite underpowered in an Ellipse with a +.75 add that he wore for years. He is now having trouble adapting to a New Comfort Short with a much higher (+2.25) add power in an almost identical frame. The main complaint is that the intermediate and near fields of vision are so narrow that they aren't functional.
So the question is... How much of the adaptation problem is the shift between the Ellipse and the New Comfort Short? How much of the adaptation problem is the shift to the higher add power?
I could switch him back to an Ellipse, but that won't solve anything if the problem is caused by the difference in the optics associated with the higher add power. If the add power isn't the problem, I could switch him to a more advanced (and expensive) lens like a Seiko Surmount or similar.
Any thoughts?
