Document Summary

Electromagnetic spectrum: the electromagnetic spectrum is the complete range of wavelengths of light and other electromagnetic energy, visible light represents wavelengths between 400 and 700 nm, but electromagnetic radiation extends in both directions beyond those boundaries. Field of view: your field of view is the part of the world you can see without eye movements, for humans, that is approximately 190 horizontally (side to side) and 140 vertically (up and down). It is also filled with fluid, known aqueous humor. In dim light, the iris relaxes control, and the pupil expands (or dilates) to allow more light into the eye. In bright light, the iris contracts and the pupil narrows, allowing less light in the eye. In this way, the pupil can range from a diameter of about 2mm to about 8 mm, depending on lighting conditions. Anatomy of the eye: the lens: the lens (also called the crystalline lens) is the adjustable focusing element of the eye.
