  1. Why Can’t We See Ultraviolet Light? An Evolutionary Biologist Explains

    Humans evolved to block ultraviolet light due to potential damage to the eye's lens, which could lead to cataracts and other vision problems. While other species like bees and birds utilize UV light for navigation and communication, the human lens acts as a protective filter, sacrificing UV perception for retinal health and visual clarity. This evolutionary trade-off prioritized sharp vision and trichromatic color perception over the ability to see UV wavelengths. AI
