Types of Light

Goggles Available in a variety of lens options and coatings. Suitable for a variety of lighting situations including indoor and outdoor.

When at work, the eye can be exposed to many different types of light depending on the task at hand. Types of light include Ultra Violet Light, Visible Light and Infra Red Light. Each type of light varies in wavelength and visibility. The human eye can only see wavelengths between 380nm – 780nm, so harmful rays are not always visible. Lenses should be carefully selected to ensure they provide appropriate protection to suit the application.

Ultra Violet Radiation <380nm Ultra Violet Light (UV) is not visible to the naked eye below a wavelength of 380nm Environment: Outside work (sun), welding arc, short circuit electric flash, work under UV. Risks: Partial blindness, cataract, photo-ophthalmia, acute conjunctivitis, retinal burn, cornea or crystalline lens lesions, loss of vision, reduction of the visual field. Protection: Indoor, Outdoor or Indoor/Outdoor Lens depending on the application - Polycarbonate provides 99.9% UV protection up to 385nm.

Visible light >380nm Visible Light has a wavelength between 380 and 780nm The visible part of the spectrum represents all the colours of the rainbow, from blue (towards 380 nm), to red (towards 780 nm). The eye is much more sensitive in the green and yellow regions. Environment: Outside Work (sun).
