A bit of an anatomy lesson for you; many don't get to see a dragon's eye up close that's focusing on far away things. Along with the 4 eyelids and double lens, we ALSO have a second iris behind the first. Can rotate it 90 degrees like an aperture for accurate depth perception.

This beautiful gaze was made by bsky.app/profile/mors.... I've been wanting an excuse to show off this insanely niche piece of D&D dragon anatomy info for a while and I couldn't have asked for anyone better!
