Problems solved by technology

Since the human eye itself cannot filter blue light, to reduce the damage of blue light to the eyes, it is generally necessary to wear glasses with professional-grade anti-blue light lenses. Ordinary coated lenses can only filter ultraviolet rays and electromagnetic radiation.

Abstract

The invention discloses an anti-blue-light film-variable lens. The anti-blue-light film-variable lens comprises a substrate, a first composite nano-film layer and a second composite nano-film layer; the substrate is provided with a protruding front surface and a recessed back surface; the first composite nano-film layer covers the protruding front surface; the second composite nano-film layer covers the recessed back surface; the first composite nano-film layer comprises a first anti-blue-light film, a second anti-ultraviolet film, a third anti-reflection film, a fourth photochromic film, anda fifth hardened film which are distributed from inside to outside; the fifth hardened film covers the center of the substrate and occupies 80% of the area of the substrate; and the second nano-film layer comprises a first anti-red light film, a second antioxidant film, a third refraction film, a fourth thermochromic film and a fifth cleaning film which are distributed from inside to outside. According to the anti-blue-light film-variable lens of the invention, harmful blue light is blocked by the nano-film layers. The anti-blue-light film-variable lens has a color-changing function which is not affected by the thickness of the lens; and the anti-blue-light film-variable lens can meet requirements for arbitrary luminosity. With the anti-blue-light film-variable lens adopted, poor effects in the prior art can be avoided.

Description

technical field [0001] The invention belongs to the technical field of lenses, and in particular relates to an anti-blue light film variable lens. Background technique [0002] Ordinary anti-radiation lenses can only filter ultraviolet rays and certain electromagnetic radiation, but not blue light. The all-round anti-blue light lens can not only effectively isolate ultraviolet rays and radiation, but also filter more than 40% of blue light. It is suitable for use when watching computers or TVs. It greatly reduces the irritation of blue light on the eyes and eliminates discomfort such as sore eyes, heat or pain. Symptoms, relieve eye fatigue. Compared with other methods and measures, wearing anti-blue light lenses has become the most effective way to protect eye health. Since the human eye itself cannot filter blue light, to reduce the damage of blue light to the eyes, it is generally necessary to wear glasses with professional-grade anti-blue light lenses. Ordinary coated ...
