Yes. You can use a photo while wearing regular glasses as long as your face and eyes are clearly visible.
However, if there is glare on the lenses or the frames cover your eyes, it may be difficult to identify your face accurately. If possible, it is better to use a photo taken without glasses.
Do not use a photo while wearing sunglasses or any eyewear that obscures your eyes.
When applying for K-ETA, use a clear photo that shows your entire face and eyes clearly.
