About photography ... I watched many portrait movies online ... many of them were illuminated by strong light ... but there was no shadow of eyelashes in the corner of my eyes. ...

It is a way to solve it with auxiliary light in ztxcfcxj's answer. Although I don't have much practical experience, I still want to provide you with a few more methods to try, hoping to help you. This eyelash must be a false eyelash. Adjusting the light direction should reduce the shadow, but it should not be eliminated. Then you can use a big reflector; Then you can use a soft box; Or the shadowless lamp mentioned by the brother below (in fact, let the light source be a surface instead of a point), as long as the light source area is large enough, there will be no shadow.
