channa pulchra,s eye looking down wards

[bathawk]

some months back I noticed that one of my pulchara,s eyes looked a little swollen so thought may be damaged it in the tank but the eye seems to be a bit more swollen and looking downwards as if it has drop eye . Don,t know what this problem is water parameters are fine have just raised the temp to 22 c to simulate the on coming of summer also eating ok.Here are some photos of the eye

the eye to right of the photo is swollen it is hard to get a shot showing both eyes the photos just don't show the difference

I have managed to get a better shot of the eyes and the last photo was when both eyes looked the same a bit puzzled as to what has happened to his eye
