Vision Restored with Total Darkness (image) Cell Press Share Print E-Mail Caption Depriving normal visual experience in one eye early in life produces a reduction in visual acuity (amblyopia) for that eye (blue circles) while the acuity of the other eye is normal (red). The visual acuity of the amblyopic eye remains low compared to the fellow eye, but after immersion in complete darkness the amblyopic eye very quickly recovers to match the visual acuity attained by the normal eye.
