What effect does anesthesia have on vision?

Anesthesia can affect vision in several ways, primarily through its impact on the central nervous system and ocular function. General anesthesia may cause temporary blurred vision or difficulty focusing due to muscle relaxation and changes in eye pressure. Local anesthetics used during eye surgeries can also lead to transient visual disturbances. Additionally, certain anesthetic agents may impact the optic nerve or visual pathways, though these effects are typically short-lived.
