If you've ever stood in the lash aisle comparing two identical-looking pairs and wondering what the heck the difference is, you're not alone. 'Cat eye' and 'doll eye' are the two most popular lash styles, but they create completely different eye shapes. In this guide, I'll break down the science of each style so you can pick the right one in under a minute.

CAT EYE LASHES: THE LOWDOWN

Cat eye lashes are designed to elongate your eye shape and lift the outer corner. The longest strands are placed at the outer third of the lash, and they gradually increase in length from the inner corner to the tail. This creates a winged, feral, done-up look that's gorgeous with wings of eyeliner.

In practice, cat eye lashes make your eyes look more horizontally stretched. They're especially flattering on round eyes and deep-set eyes, because they add that upward sweep that balances a very circular shape.

DOLL EYE LASHES: THE LOWDOWN

Doll eye lashes, as I explained earlier, put the longest strands in the center. They create a rounder, younger, more 'open' eye effect. Doll eye lashes are the lash style you want when you're going for dewy, romantic, or first-date makeup.

They work beautifully on hooded eyes, because the center length opens up the visible part of the lid. They're also great on close-set eyes if you keep the inner corner length moderate, because they visually space the eyes out.

HOW TO CHOOSE BETWEEN THEM

The golden rule is: choose the lash style that works against your natural eye shape, not with it.

• If you have round eyes, cat eye elongates them. Doll eye makes them rounder.
• If you have close-set eyes, cat eye pulls the focus outward. Doll eye can bring it inward if you choose a strong center.
• If you have low eyebrows, cat eye lifts the area. Doll eye can make the space feel crowded below the brow.
• If you have tired-looking eyes, doll eye makes you look more awake. Cat eye can look a bit heavier after a long day.

My honest advice? Have both shapes in your kit. The 'right' one depends on the occasion, your makeup, and how you want to feel that day.

CAT EYE VS DOLL EYE: THE FINAL COMPARISON

If you still want the best of both worlds, there are hybrid styles that combine a center-heavy doll effect with a subtle outer lift. They're rarer, but worth hunting for.

Are cat eye lashes more lifting for hooded eyes?

Actually, doll eye lashes are usually better for hooded eyes because they open the center of the lid. Cat eye lashes with too much outer length can get lost under the fold on the outer corner.

Which lash style is better for round eyes?

Cat eye lashes are generally more flattening for round eyes, because they add length rather than making the eye appear rounder.

Can I combine cat eye and doll eye lash styles?

Yes. Look for hybrid styles with extra length in the center and a small wing at the outer corner. They offer the wake-up effect of doll eye with the lift of cat eye.
