FIELD: physics.
SUBSTANCE: claimed eye lens comprises five lenses integrated into three positive optical components. The lens first and last components are composed by glued lenses while the central component is convexo-convex lens. Said glued lenses are made of glass with reflectivity constant ne≥1.69 at dispersion factor difference µe≥26 while glued surface of the last lens is directed by concavity toward the observer eye.
EFFECT: higher image quality at the edge of angular field of vision.
