In this age of competition every single click and every single buyer is crucial for the success of the business. For any website to be successful and generate revenue, it needs to be first observed by the visitor. The vision of all the human beings is not the same. The different types of vision are as follows.
Normal Vision
People with Normal vision have a normal eyesight and can mostly watch any website without any difficulty.
Low Vision
People with low vision have to take the help of glasses to watch the websites. The number of people with low vision is quite significant and the accessibility of the website by these sorts of people needs to be checked thoroughly. Some of the ways to make the website comfortable for people with low vision are as follows. The headings and borders should be used to clearly differentiate the various sections and parts of the website. The flashing text and the scrolling should be avoided. The images should be void of embedded text. When a text is embedded into any image, the screen magnifier will result in a fuzzy or blurred image. The content of prime importance should be placed at the top so that the visitor with low vision knows whether to continue reading or not.
Color Blindness
This is a genetic visual defect that is inherited. Most of the people suffering from color blindness have difficulty at recognizing the red color and green color. The best way to make the website readable by people suffering from color blindness is to avoid using the red and green color. Instead of using these two colors, it is better to highlight those words using bold font or the under line. The tools recommended for making the website readable by color blind people include Colorblind Web Page Filter and AccessColor.
Partial Blindness and Total Blindness
The intensity of blindness is the only difference between partial blindness and total blindness. Some of the ways to make the website understood and readable by people with partial and total blindness are as follows
Screen readers can be used for the description of the images in words but this is only possible if the title and alt tags are connected with the images. This implies that descriptive tags should be added to the images.
The source code is the basis for the screen readers. This implies that the arrangement of source code should be perfect and properly readable by the screen readers.
The HTML code used for the building the website should be validated by the validator. This helps to keep the code clean and at the same time correct interpretation by the screen readers.
Some of the programs that can be used for testing the accessibility of the website are Cynthia Says, Web Anywhere, WAVE, and aDesigner.
