Giving humans animal-like night vision through gene editing technology may be a complex and challenging task. Here are some theoretical ideas: 1. **Study animal night vision genes**: First, we can study the genomes of animals with excellent night vision (such as owls or cats) to find out the key genes related to night vision. These genes are usually related to the function of photoreceptor cells (such as rods) in the retina. 2. **Opsin protein**: The night vision ability of many animals is related to different types of opsin proteins in the eyes, which can be more sensitive to light signals in low-light environments. Through gene editing technology, such as CRISPR-Cas9, humans can theoretically introduce or enhance these opsin genes in the retina. 3. **Increase rod cell density**: Rod cells in the human retina are responsible for vision in low-light conditions. Through gene editing, it is possible to increase the number of these cells or improve their light perception ability. 4. **Bioluminescence technology**: In recent years, some studies have proposed that the retina can detect infrared light by injecting carbon nanoparticles. Although this method does not belong to traditional gene editing, it can be combined with genetic technology to enhance the effect. It should be noted that most of these methods are currently in the theoretical and experimental stages, and many ethical issues and technical challenges need to be resolved before they can be actually applied to humans. The application of gene editing on humans involves complex ethical considerations, such as safety, unforeseen side effects, and long-term effects on the human gene pool. Therefore, any related research needs to undergo rigorous ethical review and clinical experimental verification.
