Kobraøje kontaktlinser

The slit pupil effect is so sharp and detailed that my friends actually flinched when I turned around at the party. They're opaque enough that I could wear them for hours without any discomfort, which made the whole snake look feel complete.

The vertical slit pupil looks incredibly sharp up close, and the opaque coverage hides my real eye completely so the effect never breaks mid-conversation. Got a solid few hours of wear in before they started feeling dry, but for a costume piece they absolutely delivered the creepy factor.

Wore these to a Halloween party and the opaque design completely hid my pupils, so the snake effect was unsettlingly real. People kept doing double-takes from across the room, especially under dim lighting.
