Eye Protection - A New Approach (Humorous) is about protecting the eyes from injury by providing a number of built-in devices. The eyelashes catch dust and light particles before they can blow into the eye. Eyebrows cushion light blows and catch falling particles before they reach the eye. Tear ducts lubricate the eyes and wash away foreign substances that can get on the eyeballs. Pupils contract to protect the eyes from bright sunlight. Blinking your eyes is a defense mechanism to protect your eyes also. These natural defenses protect the eyes from minor injuries, but they are not sufficient to protect our eyes from heavy exposures that exist in industry today.
