Flatter your eyes with some lashes. These hold on longer than other fake lashes. False eyelashes  can stay on for at least 3-7 days.

According to shopblashed.com: Aside from the impact on your look that it creates, falsies actually benefit your natural lashes. Unlike mascara that can make your lashes brittle and weak, false eyelashes act as an alternative to reduce the impact on your natural lashes, thus allowing them to grow thicker and healthier.
