Chameleons have a unique method of keeping their eyes clean. They circulate fluid around inside their eye to clear debris, so if you notice squinting/bulging on occasion, this is normal. It’s only when symptoms persist more than 24 hours that you should be worried.

Symptoms

• Swollen eye(s)
• Fluid “weeping” from the eye
• One eye perpetually closed, even during the day
• Rubbing/scratching at affected eye
• Not eating

Cause

• Poor ventilation
• Scratches
• Bacterial infection
• Vitamin A deficiency
• Dehydration

Treatment

Chameleons rely heavily on their eyesight, so if you notice that your chameleon’s eye seems swollen or demonstrates another other symptom, make an appointment with a certified reptile veterinarian immediately. They will likely flush out the eye and prescribe a saline solution and antibiotic.

Wild chameleons keep themselves clean via rain in the wild. In captivity, regular misting/showers is one of the best ways to help your chameleon keep their eyes clean.
