Although, they are the second largest mammalian order, several aspects of their life still remain only poorly understood. This particularly holds for predator–prey interactions; we had only limited knowledge on the spe...

Intermittent Episodes of Bright Light Suppress Myopia in the Chicken More than Continuous Bright Light

PURPOSE Bright light has been shown a powerful inhibitor of myopia development in animal models. We studied which temporal patterns of bright light are the most potent in suppressing deprivation myopia in chickens. METHODS Eight-day-old chickens wore diffusers over one eye to induce deprivation myopia. A reference group (n = 8) was kept under office-like illuminance (500 lux) at a 10:14 light...
