Visual impairment questionnaire for dissertation (self.Blind)
submitted by Bzahh
Hey guys, I am currently investigating the importance of accessibility tools within social media applications for my dissertation. If you suffer from visual impairment of any sort (short/long sightedness, colour blind, etc) then I kindly ask you to take part in this questionnaire, which should only take a couple of minutes. More information is included in the questionnaire which can be found below. Thank you very much!

Usually, when people talk about near sightedness or far sightedness, they are referring to refractive errors, which can be corrected by lenses.
If you mean legal blindness, the definition is 20/200 or worse in the better eye *after correction*. That is important because my glasses are -15, which is stronger than some of my clients, but my visual acuity after correction is 20/25 (which wouldn't be legal blindness). Not sure if that matters for your paper, but refractive errors are generally not considered visual impairments (unless you are referring to extreme cases). Almost 50% of the world's population has some myopia.
