thank you so much i ordered computer glasses after firewalker had given me the numbers for my rx i think that i am going to need something closer then that though
i have the screen about 28 inches from my face normally i work about 12 inches from the table surface (it's on an incline, so it isn't as bad as it seems) i am thinking i need either a true bifocal for this or a reading glass i do look up for reference material that is at time about 18 inches away this getting old thing can be difficult to navigate at times vi On Apr 23, 2:00 pm, rdclark <[email protected]> wrote: > Many people do that.
