Take a head-on photo of both eyes today. File with the date. Compare in 48 hours if anything looks off.
Eye gunk: what it means and what it does not.
Brief end-of-day eye-rubbing is normal grooming. Persistent crust, swelling, or a closed eye through the morning is not — call the vet that week.

Chameleons clean their eyes by rotating the turret and pushing the lid against a leaf or branch. A bit of debris at the corner after a meal is fine. What is not fine: thick yellow discharge, asymmetric swelling, an eye held closed past mid-morning, or an animal that grooms one eye obsessively for more than a day.
Causes range from minor (a piece of substrate) to serious (UVB-related cornea damage from coil bulbs, vitamin A deficiency, or active infection). Photograph the eye in even light and date the photo. If symptoms persist past 48 hours, book the ARAV-listed reptile vet — eye issues escalate faster than most other complaints.
