The cornea, the transparent outer layer of the eye, plays a crucial role in our vision. It is responsible for refracting (bending) light as it enters the eye, accounting for approximately 75% of the eye's total focusing power. The cornea's unique shape and structure allow it to: 1. Refract light: The cornea bends light, directing it towards the pupil. 2. Focus light: The cornea's curvature helps focus light onto the retina. The remaining 25% of the eye's focusing power is attributed to the lens, which fine-tunes the focus by changing its shape. A healthy cornea is essential for clear vision. Any abnormalities or damage to the cornea can lead to vision problems, such as: - Astigmatism - Keratoconus - Corneal ulcers - Corneal scarring Regular eye exams can help detect any corneal issues, ensuring proper care and treatment to maintain healthy vision.
