Protective eyewear in the form of goggle, glasses, and shields provides the principal means to ensure against ocular injury, and must be worn at all times during laser operation. Laser safety eyewear (LSE) is designed to reduce the amount of incident light of specific wavelength(s) to safe levels, while transmitting sufficient light for good vision.
Different wavelengths of light are absorbed in different parts of the eye. Visible light reaches the retina for image perception. Other wavelengths interact with eye tissue differently. Where the laser energy will be absorbed in the eye depends on the light's wavelength.
