Eyelash extensions can be customized to suit different eye shapes and enhance their natural beauty. Here are some popular eyelash extension styles for different eye shapes:

1. Almond-shaped eyes: Almond-shaped eyes are naturally balanced and can pull off many different eyelash extension styles. However, a classic or hybrid lash style can enhance the natural shape of the eye.
2. Round eyes: For round eyes, a cat-eye lash style can help elongate the eye and create a more lifted look. Longer lashes placed at the outer corners of the eye can create a winged effect.
3. Hooded eyes: Hooded eyes have a natural droop to the upper eyelid, so a natural and soft lash style is best. A classic lash style can enhance the natural shape of the eye without making it look too heavy.
4. Monolid eyes: Monolid eyes have a flatter eyelid without a crease. A curling and lengthening lash style can help open up the eye and create definition.
5. Deep-set eyes: For deep-set eyes, a natural-looking lash style that adds volume and length to the center of the eye can help create a more balanced look.

Overall, when choosing eyelash extensions, it's important to consider your natural eye shape and the look you want to achieve. A professional lash artist can help you choose the best style for your eye shape and desired outcome.
