Goggles are a kind of glasses that can change the intensity and spectrum of the transmitted light to avoid damage to the eyes caused by the radiated light. It is inevitable that there will be some strong glare or ultraviolet rays in our lives, which can cause great damage to people's eyes and induce eye-related diseases. For driver friends, it is easy to cause traffic accidents. The emergence of goggles can solve this problem. So what are the functions of goggles?
The role of goggles
The role of goggles is to protect the eyes and face from electromagnetic waves such as ultraviolet, infrared and microwave radiation, dust, smoke, metal and gravel debris, and chemical solution sputtering damage. For the driver friend:
1. Anti-glare
When driving after snow, our field of vision is all white. We are prone to misjudgment when driving, and it is also detrimental to our driving. Eyewear sunglasses can effectively reduce glare and let us have With a clear vision, if there is an emergency, we can also make timely judgments to reduce our losses, and will not cause unnecessary losses to us due to glare. The anti-glare function can well avoid light problems. The resulting accident.
2. Avoid reflections
When we drive at night, we often encounter vehicles with high beams, so we don’t have a good view when driving. If we don’t have goggles, we will easily cause road errors when driving at night because of the high beams of the other vehicle. The verdict led to a series of traffic accidents.
Material of goggles
When the lenses of the goggles are manufactured, some metal oxides, such as iron, diamond, chromium, strontium, nickel, manganese, and some rare earth metal oxides such as neodymium, are added to the general optical glass formulation. These metal oxides enable the glass to selectively absorb electromagnetic waves in a certain range of light. For example, oxides of cerium and iron can absorb a large amount of ultraviolet rays. The use of this glass lens can reduce the amount of certain wavelengths passing through the lens and reduce or prevent damage to the eyes. Different colors of protective lenses can absorb light of different colors. This kind of glasses is divided into two categories, one is the absorption type, the other is the reflection type, the former is the most used.
Lens raw films are generally round. The goggles we choose should be products that have been inspected by the product inspection agency; the size of the goggles should be suitable for the user’s face; the lens is worn and rough, and the frame is damaged, which will affect the vision of the wearer. Must be replaced in time.
