Zoom, minimum text size and magnifiers are defense mechanisms. The basic problem is the pervasive offense - not respecting users' font size choices by incorporating them at 100% for the bulk of content. Thus, an even better way to address presbyopia is to design to make defenses unnecessary in the first place. > It's rather difficult to overstate the issue when over the course of time, > presbyopia is pretty much 100 percent universal within the human > population. -- No Jesus - No peace , Know Jesus - Know Peace Team OS/2 ** Reg.
