Amber light produces hyperopia in tree shrews


In monkeys and tree shrews, narrow-band red light disrupts emmetropization, slowing axial eye growth and producing substantial hyperopia. We asked whether exposure to ambient amber light (lower cutoff - 530 nm), which also stimulates only the long-wavelength sensitive cones but with greater effective illuminance, produces a similar hyperopiagenic effect.
