I have a visual impairment, it's caused by a condition known as Nystagmus. The short explanation is that my eyes constantly move involuntarily and because of this it is difficult for me to focus on fine details, the further away they are the harder it becomes. With most things close up I can manage quite well, this is something I have lived my whole life with so as you can imagine it's something I've learned to compensate for or find workarounds.
Computers, and technology in general make my life easier, the fact you can change the resolution of a screen and scale fonts to a comfortable size makes a world of difference for me. Existing in a world without the internet when I was a kid was very difficult, accessibility was always an afterthought, arguably it still is, but the assistive technology that exists today to aid me is designed to work with products and services that didn't add accessibility, but that technology enables it nonetheless - magnifiers, screen readers, audio transcription, larger screens, lower resolutions, adjustable DPI to name a few.
Using the internet when I was younger wasn't so easy before browsers added these abilities as features or before operating systems incorporated accessibility features on a native level that actually functioned. In the days of yore, I relied upon expensive third-party software which thankfully I didn't have to pay for as there were government grants you could access at the time here in the UK to gain access to the technology.
