KELFEEAO 2pcs Eyepiece Eye Cup, 41mm Diameter Flat Angle Rubber Eyepiece Cover Scope Accessories for 37.5 to 39mm Stereo Microscope Telescope

[Comfortable Rubber Construction]​ These microscope eyepiece eye cups are made from soft, flexible rubber that provides a comfortable seal around the eye socket, reducing strain during extended viewing sessions. The rubber material is gentle on skin, prevents slipping, and creates a light barrier that minimizes peripheral glare, helping you maintain focus on the specimen.

[Flat-Angle Foldable Design]​ Featuring a low-profile, flat-angle shape, these stereo microscope eyepiece eye cups can be folded inward for compact storage when not in use, making them convenient for travel or storage in microscope cases. The flat design also allows users who wear glasses to position their eyes closer to the eyepiece without removing their spectacles, offering versatility for different users.

[Secure Fit for 37.5-39mm Eyepieces]​ With an inner diameter of approximately 41 mm and a 1 mm thickness, these eyepiece covers are designed to stretch and securely fit standard stereo microscope eyepieces with outer diameters between 37.5 mm and 39 mm. The snug fit prevents the eye cup from rotating or detaching during use, ensuring consistent placement and comfort.

[Easy Installation & Removal]​ Designed as direct replacement parts, these microscope eyepiece eye guards can be quickly installed by stretching them over the eyepiece and aligned as needed. Removal is equally straightforward, allowing for easy cleaning or replacement without tools, making them accessible for students, lab technicians, or hobbyists.

[Dual-Pack for Replacement Convenience]​ This set includes two identical eyepiece eye cups, providing a spare in case of wear or damage, or allowing you to equip both eyepieces on a binocular stereo microscope for uniform comfort. The two-pack offers value and practicality, ensuring your microscope remains functional and comfortable during individual or shared use.
