Information about Eye Protection
Also see Personal protective equipment: Eye protection.
Eye protection refers to protective clothing for the eyes, which comes in many types depending upon the threat that is to be reduced.
- Safety glasses protect against flying debris but may also protect against visible and near visible light or radiation.
- Sunglasses protect against high levels of visible and ultraviolet light.
- Welding glass is a more extreme implementation of the same idea, suited to the more intense light generated during welding. Grade 14 welding glass (which is much stronger than sunglasses) can also be used to stare directly at the sun (i.e. to view a solar eclipse).
- Goggles are forms of protective eyewear that usually enclose or protect the eye area in order to prevent particulates, infectious fluids, or chemicals from striking the eyes.
- Laser protection eyewear is used to protect eyes from damage from visible and invisible wavelegths of laser light. They can be similar to goggles or be lenses incorporated into other pieces of protective eyewear. Intrabeam viewing of lasers usually requires a low power laser even with protective goggles. Laser protection goggles work on the basis that laser light is one frequency, making it easy to filter out. Laser goggles are subject to degradation and damage like any other kind of eyewear. See laser safety for further information.

Eyes are organs of vision that detect light. Different kinds of light-sensitive organs are found in a variety of organisms. The simplest eyes do nothing but detect whether the surroundings are light or dark, while more complex eyes can distinguish shapes and colors.

Light is electromagnetic radiation of a wavelength that is visible to the eye (visible light). In a scientific context, the word "light" is sometimes used to refer to the entire electromagnetic spectrum.

Radiation as used in physics, is energy in the form of waves or moving subatomic particles. Radiation can be classified as ionizing or non-ionizing radiation, depending on its effect on atomic matter.

visible spectrum (or sometimes optical spectrum) is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum starts with wavelengths slightly shorter than the wavelengths humans identify as the color violet

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle

solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring Earth's view of the Sun. This configuration can only occur during a new moon, when the Sun and Moon are in conjunction as seen from the Earth.
