During the film V for Vendetta, the character Delia Surridge recounts her experiences at Larkhill in her journal. She describes V developing abnormal abilities and kinesthesia, and when encountering V while the facility is burning to the ground, writes "...he looked at me, not with eyes - there were no eyes - but I know he was looking at me because I felt it."
Was V physically blind as a result of the experiments performed on him at Larkhill (or perhaps due to the fire), but somehow he compensated with his other heightened senses?
