Here is a difficult question
« on: October 02, 2014, 10:21:16 PM »
Hi :) Here's an interesting question.

My father is 52, he has multifocal glasses , which means he sees different in every distance. for example, a +1.5D for far, +2.75D for close, etc. Basically his eyes are very bad on all distances.
How can he improve his vision using print pushing?

He needs hyperopic defocus. So when reading books his close prescription should be about -2D lesser, read at the edge of blur (starting) at far and then when improving reading closer and then more diopters lower or minus. A +3/4 positive refractive state is good for night vision.

Accommodation rock might be helpful in order to make his inner lens more elastic for close reading.
