What factor affects how eyeliner appears?

• A. Lash length
• B. Eye shape and size
• C. Eye color
• D. Skin tone

Answer: (B)

Where the eyeliner sits and how it reads on the eye is determined by eye shape and size. The geometry of the lid—whether there’s a visible crease, how much lid space there is, and how close the lashes come to the lid—changes how a line appears when the eye is open or closed. The same color and thickness can look bold on one eye and subtle on another because almond, hooded, round, or close-set eyes all present different canvases for the liner. Lash length can influence how much the lashes reinforce the line, but it doesn’t set the line’s basic path. Eye color and skin tone affect contrast—how stark the line looks against the iris or skin—but they don’t change where or how the line sits. So the eye’s shape and size most strongly determine eyeliner appearance, guiding where to place the line, how thick it should be, and whether a wing will help balance the eye’s proportions.
