Coloured contact lenses

Decorative contact lenses that change eye colour or add effects for cosplay; they always need a fitting and prescription from an eye-care professional.

Coloured contact lenses are cosmetic lenses that change how your eyes look, from a subtle colour shift to cat-eye slits, solid white or black designs, or patterns that react to ultraviolet light. Many cosplayers use them to match a character's distinctive eyes more closely than makeup alone can. However a pair is labelled (cosmetic, decorative or zero-power), contact lenses must be fitted and prescribed by a qualified eye-care professional, and in many countries the law treats them as medical devices. Lenses bought without a prescription from costume shops, market stalls or unverified online sellers can scratch the cornea, starve the eye of oxygen, or cause infections that lead to lasting sight damage. Never share lenses, follow your practitioner's advice on wearing time, cleaning and replacement, and take them out and get help straight away if an eye becomes red, painful or your vision changes.
