Hi,
I wear glasses and wanted a better eyecup. In the end I bought https://www.amazon.com.au/Silicon-Camera-Eyepiece-Fujifilm-Installation/dp/B08W2CHGGY (Soft Silicon Camera Extend Eyecup Eyepiece for Fuji Fujifilm X-S10 XS10 X-T200 XT200 Camera, Hot Shoe Mount Installation).
However, I did not like the rubber as it got in the way of the LCD panel. It is simple to remove it, and, in the end, I just glued another rubber o-ring onto the eyecup and trimmed it slightly to at the bottom, so the screen opens perfectly.
I experimented with rubber cups styles from other cameras but could not get one that I liked and fitted.
Cheers
