Hunter eyes refer to eyes that are deep-set and lack eyecel traits. It is a quality associated with top-decile SMV. It’s not only the incelosphere that regards such deep-set eyes preferable, just look at any modelling agencies and most of their models have a similar set of eyes.
Some argue that vertical narrowness of the eyes has little to do with attraction, as exemplified by models with large eyes, including David Gandy. Females have large eyes relatively to their skull due to greater scleral show. However, it’s not only due to scleral show. Females have smaller skulls which makes their eyes appear larger.
