These rubber microscope eye guards have an inner diameter of 32.5mm mounting size. The eye guards stretch slightly by 1mm, to fit eyepieces with an outer diameter of approximately 32.5mm to 33mm. The inner lip (2mm, 0.08 inch) holds the eye guard in place to prevent it from sliding down on the eyepieces. One pair of eye guards contains 2 pieces. Please measure the outer diameter of your eyepiece. Other sizes are available for eyepieces of different outer diameters. .tb_part { width: 100%; border: solid 0px #ccc; font-size:12px; margin-top:-15px; } .tb_part tr { height: 30px; line-height: 30px; } .tb_part td { white-space: nowrap; } .tb_part_1 td { white-space: wrap; } .normal{ border-left:solid 2px black; border-right:solid 2px black; } .tb_part tr.normal td { border:solid 1px #ccc; padding-right:5px; } .tb_part tr.normal:nth-child(2){ border-top:solid 2px black; } .tb_part tr.normal:first-child{ border:none; } .tb_part tr.normal:first-child td{ border:none; font-weight:bold; font-size:16px; } .end-border{ border-bottom:solid 2px black; } .tb_part tr.memo,.tb_part tr.memo td{ border:none; } No Optical Data Show more
