Extreme cosmetic surgery to achieve 'anime eyes' (excessive enlargement of the eye opening) should be avoided, as excessive exposure of the white of the eye beneath the iris causes severe dry eye and risks permanent damage to vision.

Dr. Youn raises a scientifically sound point regarding the risks of this body modification. In ocular aesthetics, excessive lowering of the lower eyelid alters the natural protective dynamics of the eye. According to an observational clinical study published in the journal *Ophthalmic Plastic & Reconstructive Surgery*, this retraction increases tear evaporation and leads to chronic, painful dry eye. The clinical guidelines of the American Academy of Ophthalmology (AAO) confirm that prolonged exposure of the cornea to open air without sufficient hydration can cause lesions (exposure keratitis) and scarring. While total blindness is a rare and extreme scenario, it remains a scientifically plausible complication if these lesions are left untreated.
