​
TEAR FILM
The tear film, a thin fluid layer covering the eye’s surface, made up of water, oils, and mucus, keeps your eyes comfortable, washes away debris, and ensures clear vision; problems with the tear film, such as dry eye disease, caused by insufficient or poor-quality tears, can lead to discomfort, blurry vision, or even damage to the cornea, but treatments like artificial tears or lifestyle changes can often help.
​
​
CORNEA
The cornea, the clear, curved surface at the front of your eye, acts like the outer lens of a camera, bending incoming light to help focus it onto the back of your eye so you can see clearly, while also serving as a protective barrier against dust, germs, and injury; problems with the cornea, such as scratches, infections, or conditions like keratoconus—where the cornea thins and bulges—can distort vision, making regular eye exams crucial for early detection and care.
​
​
CORNEA
The Sclera and Conjunctiva: The sclera, the white outer shell of your eye, provides structure and protection, much like the frame of a building, while the conjunctiva, a thin, transparent layer covering the sclera, keeps it moist and guards against infection; irritation or infection of the conjunctiva, known as conjunctivitis or “pink eye,” is common but usually treatable, while the sclera’s health is crucial for overall eye stability.

Basic Eye Structures and Their Functions:
-
Cornea: Role in light refraction and protection.
-
Lens: Focusing light and changes with age (e.g., presbyopia).
-
Retina: Conversion of light to neural signals, including photoreceptors (rods and cones).
-
Optic Nerve: Transmission of visual information to the brain.
-
Iris and Pupil: Regulation of light entry.
-
Sclera and Conjunctiva: Structural and protective roles.
-
-
Supporting Structures:
-
Vitreous Humor: Role in maintaining eye shape and transmitting light.
-
Aqueous Humor: Nourishment and pressure regulation (link to glaucoma).
-
Extraocular Muscles: Eye movement and alignment (link to strabismus).
-
-
Advanced Concepts:
-
Visual Pathway: From retina to visual cortex, including the role of the optic chiasm.
-
Accommodation: Mechanism of focusing on near and far objects.
-
Tear Film: Composition and role in eye health (link to dry eye).
