How To Choose Better Night Driving Glasses?
Choose and buy glasses to use a special night with anti - strong night driving lens. The demand is to block 80-90% of the strong lights and harmful lights, and at the same time to make the road more clearly. Choose glasses with thicker lenses, they are more durable and protect the eyes of drivers against irritation and accidental breakage. As common sunglasses and color-changing glasses are only suitable for daytime wear, wearing them at night will seriously affect the driver's vision.
Common light yellow night driving glasses can only block a small amount of light, and is not very suitable for night driving glasses standards. Therefore, in the choice of lenses of night driving glasses, we must do the selection and demonstration of the national authority of the formal institutions to test products, to achieve the desired effect in actual use. Don't buy products that are not up to standards from vendors. Such products not only do not block the lights but may affect the driver to see the road ahead, affecting the safety of the train operation.
Consider possible uncertainties after the lens is installed.
Usually, in-store frames are made of plastic samples rather than actual lenses, so they weigh slightly less. However, it is necessary to consider the approximate weight of the lens in advance according to its own degree when trying it on, in case the weight is not suitable for real wearing. If the pupil distance is too small, it is not suitable to wear a wider frame. The machinist should strictly follow the left and right pupil distance instead of taking the average, otherwise, there will be pupil distance error in the left and right eyes, which will cause discomfort in wearing.
Who is suitable to wear progressive lenses
Progressive multifocal glasses are suitable for people with presbyopia or visual fatigue, especially teachers, physicians, musicians, computer operators, etc. They not only need to see far and near objects, but also most of the time, need to see objects at intermediate distances such as blackboards, piano scores, and computer screens. A pair of scientifically customized progressive multifocal glasses can simultaneously meet the needs of distance use, near use, and various distances in between. Some special young myopia patients wearing progressive multifocal glasses can also be used to correct the refractive power and effectively relieve eye fatigue.
Is it true that green film prevents blue light?
Some lenses filter out harmful blue light by reflective multiplayer coating. The lens has a bright blue-violet coating. Green film anti-blue lens relies on the lens material itself to absorb blue light. Therefore, it is impossible to know if the lens can really block the blue light only by looking at the film layer. Instead, it is necessary to use the test equipment of blue light blocking rate or ask the manufacturer to provide relevant experimental data. There is no problem wearing an anti-blue lens unless the user has a high demand for color authenticity, like painters, graphic designers, etc. Because when using anti-blue glasses to see white blue objects, there will be a certain color deviation. It is up to the above workers to make their own decisions.
Disadvantages of glasses
They can distort vision, especially at the edges of lenses if you have strong prescriptions or astigmatism. Some people have trouble adjusting to progressive lenses. These lenses fog up and splash in the rain. Due to the limitation of the frame itself and the effect of the prism effect in the peripheral part of the glasses, the wearer can see a relatively narrow field of vision.
How to choose the right glasses for myopia?
Nowadays, people are nearsighted, and they usually think of going with a pair of glasses. However, only from the media, we continue to see that there are substandard myopia glasses and frames in the report, so how should we choose when we buy glasses? How can I match a pair of suitable and high-quality glasses? Different glasses shops vary greatly from optics technology to the quality of lens frames, so different shops have different prices. Faced with a variety of glasses, how should we choose? Generally, we can look at these four standards. First, take a look at whether the eyewear company has obtained a production license for eyewear products. Second, see if the optometry equipment and testing instruments of the glasses companies have qualified marks. Third, see if the optometry and production staff are certified to work. Forth, look at whether the glasses have a conformity mark (certificate). The four certificates of eyewear companies are the prerequisite to ensure the quality of glasses.
