Special antiglare optical lens for driver and production method thereof

Abstract

The invention discloses a special antiglare optical lens for a driver and a production method of the special antiglare optical lens. A multilayer film coats each of the outer surface and the inner surface of a substrate of the lens, and more than one layer of antiglare film coats each of the outer surface and the inner surface of the antiglare optical lens, so that the antiglare effect of the lens is strengthened. According to the production method, the outer surface and the inner surface of the substrate are respectively evaporated with the film to form the antiglare optical lens, and the production method comprises the following steps: (1) cleaning the substrate; (2) drying the cleaned substrate; (3) cleaning the substrate again in a vacuum chamber of an electron beam evaporation machine before coating; and (4) coating the substrate: the coating of the substrate comprises the coating of the film on the outer surface of the substrate and the coating of the film on the inner surface of the substrate. The special antiglare optical lens for the driver produced by the invention has the effect of preventing harm of harmful glare and ultraviolet ray to a human body, so that the driving of the driver is safe. The special antiglare optical lens for the driver also has the functions of oil contamination prevention and autonomous optical regulation and control simultaneously.

Description

technical field [0001] The invention relates to a driver-specific anti-glare optical lens and a manufacturing method thereof. Background technique [0002] With the change of modern life style, we face the stimulation of strong light for a long time every day, such as high beams of cars, computers, TVs, mobile phones, LED lights, outdoor sunlight, etc. Little do they know that these strong lights have short wavelengths and high energy, which can easily cause dry eyes, photophobia, fatigue and other premature cataracts and spontaneous macular degeneration. Strong light exists in (280-780 nanometers) and accounts for about 50-60% of visible light, and the high beam lights of cars have always troubled people's daily life, especially at night when you drive a vehicle on the road and encounter a car The strong light of the high beam lights will seriously affect your vision at this time. The blind spot in the line of sight will easily cause traffic hazards, especially on the expr...

Problems solved by technology

What is even more troublesome is that some myopic drivers are particularly sensitive to lights when driving at night. When the strong light from the high beam of the other car hits the driver's eyes, it will cause glare, causing blind spots to appear in front of the eyes, and traffic lights at intersections The recognition ability at night is very poor, and the countdown numbers of traffic lights cannot be clearly distinguished, especially for drivers with myopia and astigmatism; this is very dangerous for driving at night; but we can choose a professional driver The anti-glare optical mirror lens makes the visual effect easy and clear, and the resolution is improved, which provides multiple insurances for people's travel safety, and provides one more visual protection for the strong light encountered in work

The optical lenses currently on the market generally have a single function, mainly for vision correction without the function of preventing glare and ultraviolet rays, and there are no flat lenses or optical lenses suitable for ordinary people to prevent glare and ultraviolet rays
