She first saw 3D at the age of 48 sitting in the driving seat of her car after a session of vision therapy. In her own words she describes her experience as seeing the steering wheel "floating in front of the dashboard with this palpable volume of space between the steering wheel and the dashboard".[11] It took her months to accept that she truly had stereo vision (stereopsis) "because of all of the scientific dogma that indicated that this was not possible".[12] She contacted Oliver Sacks, with whom she had spoken of stereopsis at an earlier occasion.
