New Interactive Tool Launches to Teach Students About the Human Eye
A new interactive tool has been launched to help students learn about the human eye. The tool allows users to label and explore the various parts of the eye, from the cornea to the retina.
The human eye is a complex organ that perceives light, movement, and color differences. It contains numerous structures, each with a unique function. The sclera, or white of the eye, provides protection and maintains the eye's shape. The cornea, the clear front surface, allows light to enter and begins the refraction process. The iris and pupil work together to regulate the amount of light entering the eye, with the iris changing color based on light levels and the pupil size adjusting accordingly. The lens further refines the light, focusing it onto the retina at the back of the eye.
The vitreous body, a gel-like substance, fills the eye, helping maintain its shape and providing nutrients. The retina, a thin layer of tissue, is where light is converted into electrical signals that the brain interprets as vision. It contains two types of photoreceptor cells: rods, which are sensitive to low light levels, and cones, which detect color. The yellow spot, or fovea, is a small depression in the retina where cones are most densely packed, providing sharp central vision. The optic disc, or blind spot, is where the optic nerve enters the eye, and while it doesn't contain photoreceptors, it's crucial for transmitting visual signals to the brain.
The interactive tool is designed to help students identify and understand the functions of these key eye structures. By using online or paper resources, students can label the parts of the eye, reinforcing their learning and enhancing their understanding of this vital organ.
