Spaceflight vs. Your Body- Why Vision Suffers

This episode spotlights Spaceflight-Associated Neuro-Ocular Syndrome (SANS)—a major risk where microgravity-driven fluid shifts raise eye/brain pressure, leading to optic nerve swelling and vision changes. Beyond SANS, we examine the full spectrum of space eye hazards: corneal abrasions from lunar/planetary dust, chemical burns, infections, and radiation effects.
