The awards are designed to acknowledge web designers and publishers who make their sites most accessible to visually impaired people. For the first time they also include a category that highlights an inaccessible site, which will be voted for by a panel of visually impaired judges.
In addition to the singer, Disney World and website rating service Blays Net Ratings have also been nominated in this category.
The winners of the charity's fourth Visionary Awards will be announced on Thursday at a ceremony in London.
A spokeswoman for the National Library for the Blind said: "Accessible design should be the rule rather than the exception."
