do not add the basking light till about 7 months of age, at that age. their basking temp should be about 78 degrees at that age, and if room temperature doesnt kick it to that, than a low wattage heat incandescent house bulb will do the trick. i do not know what to tell you honestly at this point. im not sure what time it is where you are, but if his lights are supposed to be off, then let him sleep. i would only use saline eye drops or turtle eye drops, but only if for sure nessesary. please try and post some good pics of the eye if possible
