Themes in Blade Runner - Eyes and Memories

Eyes and Memories

Eye symbolism appears repeatedly in Blade Runner and provides insight into themes and characters therein. The film opens with an extreme closeup of an eye which fills the screen reflecting the hellish landscape seen below. When reflecting one of the Tyrell Corp. pyramids it evokes the all-seeing Eye of Providence.

In Roy's quest to "meet his maker" he seeks out Chew, a genetic designer of eyes, who created the eyes of the Nexus-6. When told this, Roy quips, "Chew, if only you could see what I've seen with your eyes", ironic in that Roy's eyes are Chew's eyes since he created them, but it also emphasizes the importance of personal experience in the formation of self. Roy and Leon then intimidate Chew with disembodied eyes and he tells them about J.F. Sebastian.

It is symbolic that the man who designed replicant eyes shows the replicants the way to Tyrell. Eyes are widely regarded as "windows to the soul", eye contact being a facet of body language that unconsciously demonstrates intent and emotion and this meme is used to great effect in Blade Runner. The Voight-Kampff test that determines if you are human measures the emotions, specifically empathy through various biological responses such as fluctuation of the pupil and involuntary dilation of the iris (as pointed out by Dr. Tyrell). Furthermore, Tyrell's trifocal glasses are a strong indicator of his reliance on technology for his power and his myopic vision. Later he is killed by Roy who forces his thumbs into Tyrell's eyes.

The glow which is notable in replicant eyes in some scenes creates a sense of artificiality. According to Ridley Scott, "that kickback you saw from the replicants' retinas was a bit of a design flaw. I was also trying to say that the eye is really the most important organ in the human body. It's like a two-way mirror; the eye doesn't only see a lot, the eye gives away a lot. A glowing human retina seemed one way of stating that". He considers the glow to be a stylistic device only, but Brion James, Leon's actor, suggests that pollution was the "cause" for the glow.

The relationship between sight and memories is referenced several times in Blade Runner. Rachael's visual recollection of her memories, Leon's "precious photos", Roy's discussion with Chew and soliloquy at the end, "I've seen things you people wouldn't believe". However, just as prevalent is the concept that what the eyes see and the resulting memories are not to be trusted. This is a notion emphasized by Rachael's fabricated memories, Deckard's need to confirm a replicant based on more than appearance, and even the printout of Leon's photograph not matching the reality of the Esper visual.

Also in the Director's Cut, when at the Tyrell corporation the owl's eyes flicker with a red tint. This was derived from Do Androids Dream of Electric Sheep?, in which real animals are rare, and owls were the rarest of all, since they were the first animals to start dying of the pollution which forced the humans to the Off-World colonies. The red tint indicates that the owl is a replicant of Tyrell's creation.
