An optical instrument designed to observe and study the internal structures and phenomena of the eye.
Greek 'entos' (within) + 'optos' (seen) + 'skopein' (to view). Coined as a specialized optical instrument for examining internal eye phenomena.
An entoptoscope is like giving scientists X-ray vision into your own eye—they can observe the floaters, blood vessels, and light-scattering patterns that normally only you experience as mysterious visual phenomena.
