Colored or “costume” contact lenses may seem like a fun way to change your look, but they can be dangerous if not prescribed by an eye doctor. Poorly fitted or unregulated lenses can scratch your cornea, cause serious infections, and even lead to permanent vision loss.

In the U.S., it’s illegal to sell contact lenses without a prescription—even decorative ones. Always get contacts, including colored lenses, from a licensed eye care professional who can ensure a proper fit and provide safe-use instructions.

Your eyes are priceless—don’t risk them for a fashion statement.
