Product: 2PCS Eyepiece Eyeshields for stereo microscopes Material: soft, flexible rubber for a secure, comfortable seal Design: flatangled shape that provides full coverage of the eyepiece to block stray light and reduce reflections Compatibility: fits eyepiece diameters 32–42 mm (suitable for most stereo microscope oculars) Adjustable fit: stretches to accommodate eyepieces within the 32–42 mm range and stays in place during use Main benefits: Improves viewing clarity by reducing light interference and internal reflections Reduces eye fatigue and strain during prolonged observations Protects eyepieces from sweat, oils, dust, and minor impacts Enhances precision and comfort for detailed work Performance: soft rubber cushions the face and creates a consistent viewing position, supporting steady observation over long sessions Package: 2 eyepiece shields per set Typical applications: Laboratory research and college teaching: ideal for researchers and students conducting extended microscopy sessions where light control and comfort support accurate observations. Medical and clinical use: useful for doctors and technicians performing examinations or pathology work that require prolonged stereoscopic viewing. Engineering and inspection: supports electronics assembly, PCB inspection, and precision mechanical work by improving contrast and reducing visual distraction. Installation and care: Stretch the shield over the eyepiece rim until it seats securely; ensure the flatangled side faces outward to block stray light. Clean with a soft cloth and mild soap solution; avoid harsh solvents to preserve rubber flexibility. What makes this product stand out: Simple, durable solution that combines lightblocking geometry with soft, adjustable rubber for comfort and protection Broad compatibility with common stereo microscope eyepiece sizes (32–42 mm) Delivered as a practical 2piece set for immediate replacement or dualeyepiece setups
