🔑 Key Concepts & Definitions

• Sclera: The tough, white outer layer of the eye that provides protection and maintains the shape of the eyeball.
• Choroid: The pigmented, vascular layer lining the back of the eye that supplies nutrients to the retina and absorbs excess light.
• Cornea: The transparent, dome-shaped front surface of the eye that refracts (bends) incoming light toward the retina.
• Lens (Cristallin): A flexible, transparent structure that adjusts shape to focus light precisely onto the retina, enabling clear vision.
• Retina: The light-sensitive inner layer at the back of the eye containing photoreceptor cells (rods and cones) that convert light into nerve signals.
• Vitreous Humor: The clear, gel-like substance filling the space between the lens and retina, maintaining the eye's shape and optical properties.
