Why do we have poor peripheral vision in day light?

Poor peripheral vision in daylight is primarily due to the distribution of photoreceptor cells in the retina. While cone cells, which are responsible for color vision and detail, are concentrated in the central part of the retina (the fovea), rod cells, which are more sensitive to light and motion, are more abundant in the peripheral regions. In bright light, the sensitivity of rod cells decreases, leading to diminished peripheral vision. Additionally, the brain prioritizes central vision for processing detailed information, further limiting the effectiveness of peripheral vision in well-lit conditions.
