turtle eyes

Question
Hi, I have three turtles and 2 of them have their eyes kind
of swollen and they are purple. When my turtle (1 of them)
wants to sleep, he closes his eyes,but cant seem to keep it
closed. (mayb it just doesnt want to sleep. i dont know)  
when i change their water, i kind of keep them in a spot
where there is almost no room and sometimes they climb over
each other and i think that they hit each others eyes. but i
dont know. please tell me if the eye is normal or if its
infected.

Answer
hello it is very possible that they are nt at teh right temps. The color you state reflects being possibly cold.
If they are climbing on eachother then it is also possible that they have injured theur eye and caused infections.

Can you tell me please the set up that you are using and heat etc. are they able to go outside?
