How to help Android users with reduced ability to see
You could try using LCD Density Changer to decrease the density (effectively increase the size of everything on-screen).  This will probably result in the bottom and right side of screens being cut off, however.

There are also (limited) accessibility options in Settings -> Accessibility.  I think it might be limited to a screen reader.

If the problem is really just things on-screen being too small, may I suggest eyeglasses?
