In this day and age, people with disabilities must have access to the Web and digital services just as they would need access to buildings or other services. There are a lot of organizations and services helping and doing just that. As I age, I have noticed my eyesight starting to fail and now I require reading glasses. I couldn't imagine what life would be without my sense of site. But there are many millions of people in the world who are living through it everyday.
Below is a video of a fantastic Organization https://www.nvaccess.org/ that provides services and open source software to help visually impaired people access to digital technology and the world wide web.

As Designers of site and Content
Consciously
think about how people with disabilities such as visual or hearing
impaired, as well as mobility impaired,etc. How they would experience
sites with as little difficulty as possible.
Being aware of color and contrast, size and layout so the site would be legible to as many people as possible.
Using things like Alt Text https://whatis.techtarget.com/definition/alt-text-alternative-text to tell Web site viewers the nature or contents of an image
Be
sure to have multiple points of contact( phone,email, social media) so
it is easier for people with disabilities to get in touch with content
