PURPOSE: A lens having a tear circulatory function and an oxygen circulation function is provided to easily supply tear and nutrient to inside and outside of the lens and to protect cornea by receiving oxygen in air. CONSTITUTION: A color unit(210) is formed on the center of a lens. The color unit has a colored layer. The lens covers sclera and cornea(101) at the same time. A plurality of tear circulation balls(215) is formed in a location corresponding to the circumference of a connection unit of the sclera and the cornea when the lens is worn in eyeball. The plurality of tear circulation balls maintains a constant angle with the lens. A tear circulation tunnel is formed in one side of the color unit. A contact unit having an expanded diameter is included in both ends of the tear circulation ball.
