Eye protection is a type of personal protective equipment (PPE) designed to prevent injury to the eye. The eyes are one of the most important organs as well as vulnerable parts of human body. Eyes are easily injured by many things such as small particles, chemicals, biological agents, strong visible light and non-visible rays.
Ear protection refers to devices used to protect the ear, either externally from elements such as cold, intrusion by water and other environmental conditions, debris, or specifically from noise. High levels of exposure to noise may result in noise-induced hearing loss. Measures to protect the ear are referred to as hearing protection, and devices for that purpose are called hearing protection devices. In the context of work, adequate hearing protection is that which reduces noise exposure to below 85 dBA over the course of an average work shift of eight hours.[1] When sounds exceed 80 dBA, it becomes dangerous to the ears.
