This list of writers, who where blind makes for interesting reading, https://blog.bookstellyouwhy.com/from-homer-to-borges-a-list-of-blind-writers. The list includes Homer (although there is debate as to whether the author of the Iliad did, in fact exist), John Milton, James Joyce and Borges.
In terms of living writers, I am aware of Giles L Turnbull, http://gilesturnbullpoet.com/ and Victoria Zigler, http://www.zigler.co.uk/victoria.htm, both of whom are blind. Coincidentally Giles and I attended Swansea University at the same time, and Giles has been kind enough to write a review of my book, “The Writer’s Pen and Other Poems“.
I have had the pleasure of meeting Victoria (Tori) and her husband Kelly. So I am personally acquainted with 2 blind writers.
I myself am also blind and have written about my visual impairment here, https://scvincent.com/2017/02/06/guest-author-kevin-morris-visual-impact/.
While being visually impaired may exert an impact on the way in which writers express themselves, this is not, in my experience a primary determinant as regards their literary output.
As always I would be interested in the comments of my readers.
