In general, it is unlikely that double eyelid surgery will affect your eyesight. Because double eyelid surgery is performed in the eyelid area, it doesn't hurt the eyeball, so it won't affect the vision. Very serious complications, such as retrobulbar hematoma, corneal puncture, acute inflammation, etc., unless there is a bacterial environment (such as a poorly disinfected or unsterilized operating room) or the operation is performed by a traveling doctor who does not know medical skills. , may affect vision. So be sure to go to a regular hospital to be a double eyelid surgery.
