A dairy farm near Moscow has begun testing virtual reality glasses designed specially for cows. Agriculture officials are betting that the futuristically decked-out bovines will experience heightened moods, which will raise milk yields in turn. Each set of glasses is designed with the cows’ physiology and visual system in mind, enabling the animals to enjoy views of summer fields year-round.

In their first round of testing, the VR headsets decreased the Moscow-area herd’s anxiety and increased its average mood as expected. A group of veterinarians participated in the design and testing process for the new devices.
