Is amblyopia worse when tired?

Amblyopia, or lazy eye, may appear worse when a person is tired due to reduced visual acuity and increased difficulty in focusing. Fatigue can affect overall eye function and visual processing, leading to more noticeable symptoms. However, the underlying condition itself remains unchanged; it is merely the perception of its severity that can fluctuate with fatigue. Managing rest and ensuring adequate sleep can help improve visual performance in individuals with amblyopia.
