👉 The term "reflectoscope" refers to a type of optical instrument that is used for viewing and reflecting light. This device consists of a lens attached to a screen or mirror, which allows the user to view an object in front of them while also reflecting the light directly back at them. The reflectoscope is often used in medical settings, such as in eye surgery, where it helps surgeons visualize the anatomy of the eye and ensure that no damage has been done to the eye's structure.
