To begin, the alfalfa plant is just that, a plant. When something is naturally derived and an evolved product of the Earth, the benefits that arise from using it are abundant. The alfalfa plant is naturally high in many essential vitamins, including A, D, E, K, and even the full family of B vitamins.
The fovea centralis (the term fovea comes from the Latin, meaning pit or pitfall) is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina. The fovea is responsible for sharp central vision (also called foveal vision), which is necessary in humans for activities where visual detail is of primary importance, such as reading and driving.
The visual information is processed through the neural circuits formed by retina cells in the opposite direction and then transmitted to the visual cortex of the brain through the axons of the ganglion cells. The blind spot is where the optic nerve (axons of the ganglion cells) leaves the retina to connect to the brain, which is located about 15 to 20 degrees away from the fovea along the horizontal temporal direction.
