I'm not familiar with the 'dark adjusted eye novel' in detail, but if it's a dark - themed and has something to do with perception like I guessed, 'The Girl with All the Gifts' could be somewhat similar. It has a unique take on how a character views the world around her in a post - apocalyptic setting.
Well, if the 'dark adjusted eye novel' is about mystery and the significance of eyes, then 'The Name of the Rose' might be a good recommendation. It's a complex mystery novel set in a monastery, full of hidden secrets and strange events, much like how the 'dark adjusted eye novel' might be. Although it doesn't have the exact 'eye' element, the overall sense of mystery and exploration of the unknown is there.
Since we don't really know the exact nature of the 'dark adjusted eye novel', it's a bit difficult to recommend something exactly similar. But if it has elements of the unknown and a touch of the macabre, 'House of Leaves' could be considered. This novel plays with the idea of perception and reality, and has a very unique and often disorienting style, which might be in line with what the 'dark adjusted eye novel' could potentially offer.
