<p>[QUOTE=&quot;Kentucky, post: 4015417, member: 33176&quot;]Talking about eyes... I became a candidate for cataract surgery 10+ years ago.&nbsp; The doctor offered four choices of lenses, 1) single vision lens adjusted to give me distance vision, but needing reading glasses 2) single vision lens adjusted to give close up vision but needing glasses for distance 3) fluid-filled lenses with built in leaf springs which would adjust for either close-up or distance vision (which he said he had never seen work) or 4) fresnel lenses which would work OK for both.&nbsp; I chose the frenel lenses and they are both good and bad.&nbsp; They are like the flat magnifiers that have concentric circles, and that is one drawback that some people tend to see concentric halos when looking at point light sources.&nbsp; That doesn&#039;t bother me, but it is true that the close-up focusing I used to be able to do is pretty much gone.&nbsp; My vision went from 20/800-20/1200 to 20/30-20/60, so I can&#039;t complain too much.&nbsp; I still need glasses with bifocals but not the coke-bottle lenses I used to wear.&nbsp; I use a magnifier when I want to check close-up details.[/QUOTE]</p><p><br /></p>
