Judging from the current level of scientific and technological development, giving humans animal-like night vision through gene editing faces many technical and ethical challenges, and is unlikely to be achieved in the foreseeable future. The night vision ability of animals is determined by the special structure and physiological mechanism of their eyes. For example, some animals have more rods, which can better perceive light changes in low light conditions, and special visual pigments. To give humans these complex characteristics through gene editing, it is necessary to precisely operate a large number of genes and their regulatory networks, which is far from technically possible. Gene editing technology is currently mainly used to study and treat relatively simple application scenarios such as some single-gene genetic diseases. For such complex goals involving coordinated changes in multiple physiological systems, there are huge technical barriers. At the same time, arbitrarily performing such gene editing on humans will also trigger a series of serious ethical, social and safety issues, such as the possibility of unpredictable genetic consequences and changes in human genetic diversity.
