The human cornea is a biological marvel — it’s the only part of the body that functions completely without blood vessels. Its transparency is essential for vision, allowing light to enter the eye without distortion. Instead of relying on blood, the cornea absorbs oxygen directly from the air, while nutrients are delivered through the tear film and the aqueous humor within the eye. This unique setup is what keeps our vision sharp, but it also comes with vulnerabilities. Contact lenses that restrict airflow can starve the cornea of oxygen, potentially leading to swelling, irritation, or even vision loss. That’s why giving your eyes time to “breathe” is more than a comfort — it’s a necessity for ocular health. #EyeFacts #Cornea #HumanBody #VisionScience #OcularHealth
