Look straight into a mirror with your face relaxed
Notice whether the iris is fully visible or partly covered by the upper and lower eyelids
Check if the eye opening looks round, almond-shaped, or narrow
See whether the outer corners tilt upward, downward, or stay level
Observe whether there is a visible crease on the eyelid
Determine if the eyelid crease is hidden by skin when the eyes are open
Check if the upper lid covers part of the mobile lid
Compare both eyes to see if they have the same shape
Identify if the eyes are deep-set, prominent, or set normally
Use a front-facing photo to compare the eye outline more easily
Match your eyes to common shapes such as almond, round, hooded, monolid, downturned, upturned, or deep-set
