Does the camera lense to housing lense distance effect image clarity?

I hope this is not too stupid of a question but I'll ask it anyway. A while back I did a dive and took some photos. When I looked at the photos on the compuiter screen the visability was noticaby lower than what I remeber it as being on the dive. I'm confident that the lenses on the housing and the camrera were clean and not inhibited in any other way such as fog. I dont think the issue I'm talking about here is backscatter as I've experienced that as well and it's different again.

Could the reason for the lower visability be caused by the air gap between the lenses of the camera and housing being small? Whould a larger air gap from an extended dry lense improve the clarity of the image?
