The actress said in an interview " As part of preparations, I looked up a few films as reference points, though didn't want to copy them. There is a certain way the eyes of the blind move, which is very crucial. But once I mastered it, I'm not able to get out of it at times. Some days, I wake up in the morning and find my eyes focusing like the blind!"
Meanwhile, the actress is reportedly busy with her exams and academics.
