LED Lighting for Horses

4 Seeing in bright and dark environments Horses have much better twilight vision than humans. However, the eye has to adjust to the respective lighting conditions. In the wild, the daylight does not just switch on and off. Sunrise and sunset are a smooth transition between light and dark, and vice versa. An abrupt change requires a period of familiarisation. When switching from light to dark in particular, horses initially see next to nothing. This short-term blindness leads to unnecessary discomfort for the horse. The time required to get used to the new light condition is longer for horses than it is for humans. Colour perception Different cones in the retina of the eye are responsible for colour perception. While humans have three different cone types, horses do not have the L cone for recognising red shades. Horses see in shades of yellow, green and blue. If you take this into account when designing lighting, you can help your horse to better perceive contrasts. The horse can then fully concentrate on other tasks.
