Blue Cut Lenses

Blue light is part of the visible light spectrum, just next to violet. Studies show that the blue-violet light emitted by many digital screens is the most harmful to eyes, according to the Paris Vision Institute. Younger people could start to experience age-related macular degeneration, a leading cause of vision loss for people over 50, due to excess blue light exposure.

Blue Cut Lens helps to protect your eyes against blue-violet light emitted by digital screens. Seesen Optics is offering different kinds of blue cut lens.
