Study Notes
Eye Structure and Function
- The retina is the innermost layer of the eyeball, responsible for converting light into neural signals.
- The vitreous humor is a gel-like substance found in the back segment of the eyeball, providing shape and support.
- Lacrimal glands are responsible for tear secretion, crucial for eye lubrication and protection.
- The black opening in the iris, known as the pupil, allows light to enter the eye; it is not the cornea.
- The lens is a clear structure that focuses images onto the retina, playing a vital role in vision clarity.
- The sclera is the white outer coating of the eye, providing structure and protection.
Common Misconceptions
- The retina is not colored; rather, the colored portion of the eye is the iris.
- The cornea is a clear front layer that helps to focus light, not the opening for light entry (the pupil).
