The correct choice of lens plays an important part in the safety glass selection process.  Consider the following features of the varied lens type available, when deciding what spectacles are needed to get the job done in particular work situations.

• Amber Lenses
  The characteristics of the filter show absorption of the blue lights in the visible range; producing contrast enhancement
• Polarised Lenses
  Polarised lenses filter glare and enhance contrast
• Smoked Lenses
  Filters harmful UV rays as well as visible light and reduces glare from artificial light
• Clear Lenses
  Provides protection against general indoor hazards
• Mirror Lenses
  The mirror coating reduces the amount of light through the lens by reflecting the glare
• Indoor/Outdoor Lenses
  A slight mirror coating on a clear lens, allows more visible light trough and reduces the glare form artificial light
