It's not a question that can be answered fully in just one paper, so Sandra focuses her discussion on two novels by Teresa Medeiros. As stated in the abstract, Sandra concludes that "Medeiros rejects various dominant cultural stereotypes about visual impairment and disability such as the disempowerment and perceived helplessness of blind characters" but she adds that,
even if in The Bride and the Beast the lack of sight becomes a vehicle to criticize the body cult in romance fiction and even if Yours until Dawn rejects many common stereotypes about disability and closes with a reference to the old body, the literal cure in both novels aims at normalizing the bodies of the protagonists and thus results in what Davis has called “the neutralizing of the disability” (542). In regard to visual impairment, this is a common trope in romance fiction, whereas other forms of disability are often used to enhance the dark appeal of the male protagonist and act as externalizations of his inner wound. Though the genre thus creates new stereotypes about disability, [...] it generally rejects depictions of disability as a disempowering force that creates helplessness and dependence. (288)-------
