lack of accessibility for blind users on many websites!

about 90% of websites are fign for normal sited users or people with no disability but not at all accessible for blind or people who have other site related disability that interferes  with how they view the web page.  the worce thing for people that are blind or with very low site, is things such as image verification that most sites use for sign ups. although some do provide audio as a alternative most don't. however even with the sites that do use audio verification  as a alternative , the audio is so distorted that its impassable to understand  a single word of it.  a much better way is having something like a question like 1+1+2=? shown as text with a text box to type the answer or a bunch of random numbers or letters that you have to type only that there shown right on the site as text. as long as the letters or questions change each time the page  is loaded this way is just as afective .
