Dear George,

I would just like to comment on your statement "all the blind are
equally blind". I think it is important to note that this is not the
case. Someone who considers themselves blind may have light perception.
They may also have a tiny amount of vision, even if it may not be very
useful. I think it is important to recognise that every single persons
vision is different, even those people who have the same eye condition,
so we can make no assumptions about what someone can or cannot see.

I hope this is helpful.

Marc, please amend your category list  to point out the vast difference 
between those who don't see and those who don't see well; their needs
quite different and what helps one group is often of no help to the
Further, while all the blind are equally blind, there is variety in the 
needs of those who still read with their eyes but not well.
Typically they suffer from (1) poor acuity (sharpness of focus) and (2)
contrast sensitivity (ability to distinguish between shades of colors or

grays).  A third difficulty is small field size, not so prevalent but 

The fix for #! is generally only half known.  Everybody knows about 
magnification.  The other part is the need for word wrap to keep copy on
screen.   Without it every line must be chased to its end, scrolling
and then left for the start of the next line.
The fix for #2 is not magnification (often suggested), but is choice of
for incoming text.  Poor contrast sensitivity calls for thicker strokes
the lines that make the characters, so the use of bold fonts is the fix.

User's software can provide them, but formatting can prevent their use. 
Magnification help only a little.  A bigger faint character is still

Enough.  To learn more, "Accessibility for Eye Readers". 12k and

| Hi Meliha,
| Simple question, simple answer. There are four categories of problems,
| people might have using a website
| vision
| hearing
| movement
| cognition
| can be less than average or (partially) non-existent (like the ability
| to see colors or to see with just one eye).
| Some things, which can be a challenge in real life, do not influence
| usage of a website a lot: like sitting in a wheel chair.
| I think this is clear. So just try to understand what needs have
| which cannot see. Can they use your site? How? It is quite easy to
| support them: they use screenreaders, programs that read your content.
| You have to provide ALL the content as text (also what is on your
| pictures). Now disable your css and look at your pages: everything
| should be linearly ordered in just one dimension: from top to bottom.
| Make sure, that the content is provided in the correct order: does it
| still make sense? Or do you use phrases like:  on the left you see...
| which is nonsense now, because there is no left or right ;-)
| Try this with other disabilties. What is a problem for people that
| cannot move very good: if they cannot put there arms way up in the
| its propably no problem to use a mouse and keyboard, but if they have
| tremor, its very difficult for them to klick on tiny buttons and
| With this approach you can find out a lot about your own site. If you
| like exoeriments: Just try to use your page with your feet instead of
| hands, wear glasses for watching 3d-movies (these with green and red
| "glass")
| And further just use your imagination.
| One thing which is difficult to understand: people whonever were able
| hear, normally do not speak even the language of there own country.
| use gestures for communication. So they cannot read your texts - at
| least only with big difficulties. So try to keep your sentences short,
| remain essentially, just write, like everybody should write anyway:
| there are a lot of descriptions/tutorials out there in the web, How to
| write texts.
| You will see - all of this improvements will help everybody to use
| site - like already saif here: accessibility ist usability for
| Good luck with your site!
