As mentioned in the first section of Lesson 2, our eyes are sensitive to a very narrow band of frequencies within the enormous range of frequencies of the electromagnetic spectrum.This narrow band of frequencies is referred to as the visible light spectrum. WTOP delivers the latest news, traffic and weather information to the Washington, D.C. region. Inflammation is a process by which your body's white blood cells and the things they make protect you from infection from outside invaders, such as bacteria and viruses. The pupillary light reflex (PLR) or photopupillary reflex is a reflex that controls the diameter of the pupil, in response to the intensity of light that falls on the retinal ganglion cells of the retina in the back of the eye, thereby assisting in adaptation of vision to various levels of lightness/darkness. Natural night vision, or scotopic vision, is the ability to see under low-light conditions.In humans, rod cells are exclusively responsible for night vision as cone cells are only able to function at higher illumination levels. and hyperopia (long-sightedness) and astigmatism, but far more e.g. Our curricular based PL is offered to everyone: childminders, early years workers, primary and secondary staff as well as lecturers, technicians and those who work with young people in non-formal settings such as youth workers and in the CLD sector. The cornea is formed from a translucent epidermal layer; the slit-shaped pupil forms a hole in the iris just behind the cornea.
