Eye dent in KSB?

Hi! I noticed today that my kenyan sand boa has a slight dent in his eye. I read that in ball pythons, this indicates a lack of humidity - is it the same thing for kenyan sand boas?

(Also, I thought it was more likely for him to be too humid, he has a succulent and a water dish in his tank at all times. And a humidity box that he spends a lot of time in...)

Thanks!

What are you using to read your temps and humidity? Most of us on this site use some brand of digital thermometer/hygrometer since they are the most accurate. If you're using one of the dial thermometers you're probably getting innaccurate readings. I used them when I first got into snakes and when I switched to digital I noticed I was off by almost 10 degrees.
