My dad just had his implants, last year. They're fixed focus, but the eye is very adaptable. He is able to see distance, and (with a little squinting) see close enough to read. He prefers a mild pair of reading glasses, for reading, since it makes it more comfortable.
In photography, there used to be a technique used to get maximum depth of field. It involved something called the hyperfocal distance...it resulted, even with a fixed focus lens, in sharp images from 3' to infinity. I imagine that my dad's implants use a similar technique. http://www.great-landscape-photography.com/hyperfocal.html -- Chuck Knight On Tue, Aug 4, 2009 at 1:03 PM, Paul<[email protected]> wrote: > > My understanding was that lens implants are fixed focus - you pick the > focus - and that you need glasses to focus at other distances.
