What are the two common types of eye shapes?

The correct answer highlights the two commonly recognized eye shapes: round and oblong, also referred to as almond-shaped. Understanding these eye shapes is essential for lash specialists, as the shape of a client's eyes can significantly influence the application and styling of lash extensions.

Round eyes are typically characterized by a wide, circular iris and a noticeable visible lid space, while oblong or almond eyes have a more elongated appearance, with a tapered outer corners and a more subtle visible lid. Lash artists can tailor their techniques based on these shapes. For instance, someone with round eyes might benefit from lash styles that elongate the outer corners to create a more balanced appearance. Meanwhile, clients with oblong eyes might prefer a more uniform lash length across the lid to enhance their natural shape.

The other options do not reflect the recognized classifications of eye shapes in relation to eyelash extensions. Thus, they do not provide the same relevance for styling and application in lash artistry.
