Can double eyelids make the eyes appear larger?

In general, double eyelid surgery can visually make the eyes appear larger, but it does not directly change the size of the eyeball itself. The results vary depending on the individual's baseline eye structure, surgical technique, and personal differences.

Double eyelid creases enhance the dimensionality of the upper eyelid, revealing more of the previously covered white portion of the eye, thereby increasing the vertical height of the eye opening (the distance between the upper and lower eyelid margins) and creating a visual effect of larger eyes. A single eyelid resembles a "narrow-framed picture," while a double eyelid resembles a "wide-framed picture," with the latter appearing more prominent and capable of encompassing more visible eye content. Double eyelid surgery only affects the eyelid structure and cannot alter the diameter of the eyeball. If the appearance of small eyes is caused by conditions such as congenital microphthalmia or axial elongation due to high myopia, ophthalmologic treatment—not double eyelid surgery alone—is necessary to address the concern.

Double eyelid surgery is not suitable for everyone, and its outcomes can vary significantly among individuals. Before deciding on surgery, it is essential to fully understand your own eye characteristics, communicate thoroughly with your surgeon, and develop an appropriate surgical plan. Additionally, postoperative care is equally important, as proper care is necessary to ensure optimal surgical results.
