According to experts from the eyeglasses network, the so-called anti-radiation glasses, that is, in the processing of the lenses of the glasses, in the material to add a number of chemical compounds in the medium, in addition to the lens on the relevant anti-radiation film layer, which can theoretically play a role to a certain degree of wave filtering. This is because the radiation from computers and other electromagnetic waves, these waves have a certain wavelength and amplitude, compound media and radiation protection film is to use this principle, so that before and after the surface of the lens generated by different wavelengths of electromagnetic waves interfere with each other, thus offsetting part of the radiation.

But the vision experts also pointed out that the above mentioned with special radiation protection function of the glasses, before the main only special industry personnel to use, the process of higher requirements, such as in the past in the radiology department of the medical staff, wear a lead content of high radiation glasses, can effectively block X-ray rays. However, ordinary manufacturers of eyeglasses may not have this technology, and it is difficult to say how effective their radiation protection is. Moreover, at present, there is no specific quality testing standard for radiation glasses for eye care, such as thickness, radiation strength, and so on, depending on the manufacturer's unilateral publicity, which is likely to cause confusion in the eyeglasses market and uneven quality of eyeglasses. In addition, anti-radiation glasses are not suitable for all people, especially some children wear red and other tinted film anti-radiation glasses, reducing the light stimulation, which is not conducive to visual development.

Common questions about radiation glasses
1
Q1: How to identify computer radiation glasses with ordinary glasses? Is there this kind of computer radiation protection lens in myopic glasses? Yesterday went to the optical store with computer radiation protection glasses, which lenses look no different from ordinary resin lenses. Sales staff to do a demonstration of this: first a cover with a glass cover of the instrument on the electricity, which immediately appeared in the rotation of the halo, which is said to be electromagnetic waves, and then the radiation protection lenses on the rotation of the halo in front of the lens in front of the light distortion, the emergence of a red point of light, she said that the lens will be ultraviolet rays, electromagnetic waves blocked on the outside; and then took out another lens blocked on it, there is no reaction. Sales staff said that this is a normal lens ultraviolet light has penetrated. I wonder if this demonstration is true or false?
A: Myopia glasses inside is also this radiation protection lens, you do not have to care too much about the staff demonstration, people should not lie to you. It is recommended that you change the monitor into a liquid crystal, that is good for the protection of the eyes, these glasses can prevent part of the radiation, mainly the eyes, but other parts of the role is not, such as the skin on the face. Long time is very easy to get color spots, to grasp the time. In fact, the computer's biggest radiation is from the day keyboard, the best way is to put a small pot of cactus next to the computer and other small plants, because the cactus has the effect of absorbing radiation, I have been using this method. So far it has been good. You can also try.

Q2: How do I pick my anti-radiation glasses? Frequent Internet eye discomfort, I want to buy a pair of anti-radiation flat glasses, but go to the market to see the eye, there are finished realm, there are now with the brand a variety of different prices, the quality of uneven (I heard that the eyeglasses industry is very violent, so the more the store is opened more and more), I do not pay attention to the name brand, only to seek anti-radiation effect to be good, affordable, how to identify it is not anti-radiation effect is good, which brand, how to I'm not sure how to do that.
Answer: anti-radiation glasses efficacy is indeed, but it is difficult to distinguish between the real and the fake, even if the business can come up with anti-radiation glasses quality test book, but also can not guarantee that consumers get the lens is really anti-radiation function, because only with the naked eye, can not judge the effectiveness of anti-radiation, so often use the computer is still not too dependent on anti-radiation glasses. How to reduce the damage of the computer to the eyes, the eyeglasses network experts gave advice: first of all, when using the computer to maintain the correct sitting posture. The distance between the monitor and the eyes should be at least 50 centimeters or more, the top of the monitor should be slightly lower than the line of sight, the position of the monitor should be 10-20 degrees below the line of sight, such a distance and angle can make the eyeballs exposed to the air to reduce the area. For every 1 to 2 hours of work, take a 15-minute break, look at distant objects, and do eye exercises. Frequent blinking can reduce the time the eyeballs are exposed to the air, avoiding the evaporation of tears, and avoiding "staring without looking". Get enough sleep, do not stay up late, drink more water, eat more fruits.

Wearing glasses should pay attention to:
1
Please pay attention to long-term contact lens wearers, do not have too long nails. It is not suitable both from the hygiene point of view and the safety point of view. Long nails can cut contact lens lenses or scratch the eyeball because the edge of the nail is not smooth enough
2
It's best not to push too hard when removing contact lenses. Don't be anxious if you don't succeed at once, just relax and readjust your grip.
3
Don't push too hard when pulling down your eyelids either. Avoid the fine lines that will arise near the eyelids over time. In short, for the safety and hygiene of glasses, how to wear contact lenses and how to take off contact lenses are issues that we should pay attention to

There are three points to be grasped when wearing eyeglasses
Whether it is wearing contact lenses or frames (eyeglasses frames), or sunglasses, a professional optometrist is indispensable. This is not only refractive error people need to carry out things, all friends in the choice to wear glasses, eye vision optometry, in order to clear the understanding of their own vision, according to the actual situation to choose a good and appropriate eyewear products. At the same time, it is also a way to understand the condition of the eyes.

How to achieve healthy wear, including the choice of eyeglass products and wear hygiene habits, especially for contact lens wearers. Because contact lenses are Class III medical devices (implanted in the human eye), the safety requirements are very high, the wearer should not only choose a good formal products, but also choose to fit their own products, and develop good wearing habits. In addition, the choice of sunglasses should also pay attention to, do not be greedy for cheap choice of poor quality products, otherwise it will be because the lenses do not have ultraviolet light and glare protection, causing greater irritation to the eyes, as well as in the color should be done to achieve a purposeful choice.

Can't make do. Frame glasses lens degree, lens wear; contact lens lens comfort; sunglasses visual clarity and so on can not make do, which are related to our eye health.
