Different coatings applied to binocular lenses serve various purposes, including reducing glare, improving light transmission, and enhancing image contrast and clarity. Anti-reflective coatings, such as fully multi-coated or multi-coated layers, minimize reflections and glare caused by stray light, resulting in brighter and sharper images, especially in bright or backlit conditions.
Additionally, phase-corrected coatings on prism surfaces help eliminate phase shift and maintain image sharpness and colour fidelity. Other coatings, such as hydrophobic and oleophobic coatings, repel water, oil, and dirt, keeping the lenses clean and free from smudges for clearer viewing in challenging outdoor environments.
