Permanent Lens Implants Raise Concerns Over Loss of Night Vision, Experts Warn

“As soon as I entered a street with no lamps during a dawn delivery, everything went pitch black. I nearly fell down the stairs I couldn’t see.”

M, a vampire working as a late-night delivery driver, recently paid three million won for a permanent lens implantation procedure that turns the pupil brown. His naturally red-glowing eyes often drew suspicion, so he opted for a permanent fix. Immediately after surgery, however, his greatest advantage — night vision — dropped to near-human levels.

Known among vampires as the ‘Eye-Mute’ procedure, the surgery involves implanting specially tinted lenses inside the eye to block natural color and light reflection, creating ordinary black or brown pupils.

Medical professionals report the number of procedures doubling yearly among office-working vampires embedded in human society. The appeal lies in convenience and reduced risk of exposure.

The danger, experts warn, is biological. Vampires possess a tapetum lucidum behind the retina that amplifies faint light. “Covering the pupil blocks over 90% of incoming light,” one ophthalmologist explained. “This effectively induces night blindness.”

Patients report warehouse blindness, near-miss traffic accidents, and panic during power outages. Some low-cost procedures may even cause irreversible glaucoma by disrupting ocular fluid flow.

Experts caution that implanted lenses adhere to eye tissue, making removal extremely difficult. “Appearing human is one thing,” they warn, “but surgeries that negate nocturnal predator biology must be considered carefully.”

Vampire rights groups have also criticized a social climate that pressures vampires to sacrifice core abilities for acceptance.
