  • Designed specifically for Microscope Eyepieces with an outer diameter of 1.25 inch (1-1/4 inch or 32mm).
  • IMPORTANT: Please measure your eyepiece to ensure fit, as 1/16th of inch (or 2 mm) will make a difference. These eye guards have an inner mounting diameter of 1-3/16inch (30mm). Rubber eye guards are supposed to stretch over the eyepiece to ensure a snug fit, therefore, they may be too loose to fit any eyepieces with an outer diameter that measures exactly 30mm or smaller. The rubber stretches slightly by (1/16th) 2mm maximum to fit eyepieces with an outer diameter of 1.25 inch (1-1/4 inch or 32mm), but will not fit any eyepieces with an outer diameter bigger than that.
  • NOTE: Designed specifically for Microscope Eyepieces, NOT FOR BINOCULARS. May not fit with other types of eyepieces of different equipment.
  • The inner lip (6mm, 0.24 inch) holds the eye guard in place to prevent it from sliding down on the eyepieces.
  • Not Foldable - the rubber piece cannot be folded back on itself.
  • One pair of eye guards contains 2 pieces.
