What is Visual Impairment?
Total blindness is not having the inability to tell dark from light. Low vision is a severe reduction in vision that can’t be corrected with contact lenses or standard glasses. Legal blindness is central vision corrected at 20/200 or worse or a visual field that is not greater than 20%. This is also called tunnel vision. Many people have difficulty reading normal print and are reporting their vision worsening to the point of requiring large print or audio.
Label All Buttons and Links
If you label links and buttons on your site to say exactly what they are, for example, ‘search’ or ‘home’, then visually impaired people can decide what they are. They can use a screen reader reading the label out loud or with magnification software.
Labeling of buttons and links mean that visually impaired don’t have to push buttons without knowing what they are. If you do use the labeling of buttons, then the visually impaired can move around your website easily.
Have an Audio Option for Captcha Verification
If you use captcha verification on your website for people that want to interact with it, you have to consider the possibility of adding an audio option.
Screen readers can’t read graphics and are usually hard for people with impaired vision to see.
Having an audio option for captcha verification offers an alternative to the visually impaired while still sustaining your website’s security.
If no audio option is available, the visually impaired will just click away from your site since there isn’t any alternative way to complete such tasks.
Add Alt Text to Images
Adding Alt Text to images on your site is possibly the best and most efficient way to make your content accessible to the visually impaired.
However, you may be surprised by the number of blogs and websites that don’t do it.
Describing what is in the image aids the visually impaired in building a picture and interpret it in their own way, meaning being more engaged with your posts.
