Vision Quest: The Art of the Contact Lens

Finding the character is the crux of acting, and everyone has their process. Filling notebooks with endless backstory details —  sure. Tapping traumatic memories to summon tears on cue — certainly. Alienating cast and crew by refusing to break character for 90 days on set — unfortunately, it’s been known to happen. All these techniques are well documented, surfacing in celebrity profiles like bubbles in a fishbowl. Another role-realization tool is discussed less: theatrical contact lenses.

Don’t confuse these sophisticated devices with the $12 contacts that Comic-Con attendees buy online to complement latex creature costumes. (Wear those one-size-fits-all lenses at your peril.) Nor should they be mistaken for the “cosmetic contacts” that allow wearers to sample a new eye color.

Think of theatrical contact lenses (FX lenses), instead, as limited-edition artworks.

These custom lenses are unique, meticulously hand-painted and require a rock-steady hand. (The FDA-approved pigments are sometimes applied with a single-bristle brush.) The talent pool for crafting them is also extremely finite. You can count the best lens painters in the world on two hands — one if you’re picky. And despite all the eyeball biometrics and 3D scans, professional fittings for these tiny marvels are more trial and error than science; actors may have to try on several prototypes before finding the perfect fit. 

All this doesn’t come cheap. A single pair of sclera lenses (contacts that cover the pupil, iris and white tissue) featuring a complex design can cost up to $5,000 per pair. But you can’t argue with the results. The best FX lenses look better in closeup than anything CGI houses can manage today. Think of the milky-green lenses Jamie Campbell Bower wore as human-turned-monster Vecna on Netflix’s Stranger Things, or the opaque alabaster contacts Maisie Williams wore as a blinded Arya Stark in HBO’s Game of Thrones season-five finale.

The golden reptilian eyes David Tennant flashed as former angel Crowley in Prime Video’s Good Omens are memorable because he wore multiple versions to convey various moods and emotions, ranging from subdued to downright demonic. For sheer volume, however, nothing beats AMC’s The Walking Dead. For 11 seasons, so many actors (principals and background) needed the show’s signature zombie contacts — cloudy, grotesque and invariably bloodshot —  that three lens technicians were frequently required on set just to shoot a single scene. 

Enhancing performances with contacts dates back to the Golden Age of Hollywood. The first FX lenses ever worn in a film were ground from German Zeiss glass for the 1939 crime thriller Miracles for Sale, and they turned an actor’s brown eyes blue. In 1967, Camelot showcased another special-effects breakthrough: the Merlin character’s mirrored contacts that provided a reflective surface for dramatic lighting effects.

The horror and sci-fi genres created more demand; think of werewolves (sunburst lenses) and space aliens (blackout lenses). The industry soon expanded, with an emphasis on verisimilitude: red subconjunctival hemorrhage lenses for burst blood vessels; arcus senilis lenses for the rheumy ring around the corneal edge that lets young actors play old; limbal ring lenses, the dark outer ring and extended color of which make the iris look dramatically larger for a wide-eyed look; dilated pupil lenses for corpses and drug-addled rock stars; and even vertical split-pupil lenses to project a feline vibe, à la Nastassja Kinski in the campy 1982 horror film Cat People.

This humble practical effect has now reached an artistic pinnacle. Some of the best examples come from the London-based outfitter Eyeworks for Film, which has provided FX lenses for shows like The Lord of the Rings: The Rings of Power (Prime Video), Dune: Prophecy (HBO) and Wednesday (Netflix). Sinead Sweeney, who cofounded EFF in 2011, says every great lens design is a team effort, with the project’s makeup designer, prosthetics department, VFX technicians and director all collaborating on the concept art. She also stresses that to add extra drama, like the “afterglow” effect EFF created for the sinister Night King in Game of Thrones, pixelated lenses are augmented with CGI during postproduction.

Even so, she doesn’t expect FX lenses to go away anytime soon, because EFF’s product is ridiculously cost-effective compared to digital options. “I’ve consulted on various shows where the producers had decided not to use our lenses due to an actor’s personal health issues,” Sweeney says. “What they find out is that the cost to recreate the same digital eye effect can cost hundreds of thousands of pounds, if not a million, for many hours of postproduction CG.” 

What does it feel like to wear these things? If properly fitted by a licensed optometrist, FX contacts are as comfortable as conventional lenses. There are, however, a few caveats. “My rules of thumb are ‘four hours in, 15 minutes out,’ and ‘lubricate the actor’s eyes with drops every 20 minutes,’” says Stacey Sumner, an optometrist at Sherman Oaks–based Professional Visioncare Associates who has worked as a lens technician on numerous series and films.

“The real problem isn’t wearing the contacts,” she says. “It’s the extreme conditions actors face when they’re working: bright lights, dirt, dust, smoke machines, fog machines —  all of that irritates the eye.” Nobody knows about this occupational hazard better than wrestler-turned-actor Tyler Mane. He suffered temporary vision loss after wearing sclera blackout lenses for a 12-hour shoot while playing Sabretooth in the 2000 film X-Men, enduring an ER procedure wherein a doc cut the lenses with a scalpel and literally pried them off his eyes. Suffering for one’s art, indeed.

“Without these contacts, characters [can appear] rather dull. Changing the look of the actor’s eyes makes a huge difference when you’re creating a character,” says Matthew Mungle, a makeup artist who has  worked on 14 seasons of CBS’s CSI franchise, for which hundreds of morgue scenes have required a specific contact lens to suggest the cause of death. “As soon as the lens tech puts in the contacts, everything clicks, and the face really pops. The transformation is almost magical.”
