Thanks for the help. However, I think the issue is related to UV lighting. I recently changed the lights from two 2ft long tubes to two screw in UV lights. I noticed that there is a very intense ultraviolet glow around everything.. That purplish blue colored aura... I read that these lights throw out much more UV which they seem to be doing.
The location that the Chuck basks at, positions him so that the eye he keeps closed is facing the UV 10.0 light. He is maybe 8 inches away from the bulb.
When I turn that light off he will open his eye, but only for a short period. I think he may have a bit of "flash" from the UV light.
A note on contact solution... The saline cleaning solutions like Renew multi-purpose lens cleaner contain high amount of protein which can cause damage to the human eye. I would think that this might apply to reptiles as well. Always use rewetting drops as they do not contain the protein. However, that type of solution also has a short shelf life. It is safe to use the cleaning solutions once or twice a day, and only a few drops at a time.
A product that I use is called Refresh PM. It is an oily ointment that helps flush debris and mucous from the eye. It also promotes healthy tear production. I put a bit of this into my little Chucks eye last night and he kept it open most of the night. (My dad is a welder, and he used this stuff by the gallon to ease welding flash!!)
Anyway, thanks for the input, and as far as the substrate... I scooped up some of the dirt, silica sand, and granite bits from the area that I caught the little guy. It is due to be changed, and I will probably go with calci sand mixed with some 1/2" sized pieces of granite gravel. He has a ton of rocks to climb on, and spends almost no time on the ground.
