Types of Optical Frame Glasses
The full-frame glasses have good strength, suitable for athletes and children to wear because the lens is completely protected by the lens ring. They are suitable for a variety of refractive parameters of the lens. The upper part of the lens ring is made of metal or plastic materials. The lower half of the lens ring is made of a very fine nylon wire like the lower part of the lens ring. Rimless glasses are lighter than full-frame glasses. Rimless glasses can be divided into parts type and integral type. The part type consists of a nose bridge (together with the nose pad) and two temples. The combination glasses are divided into two parts. Usually, the front group is equipped with colored lenses, and the rear group is equipped with lenses for correcting refractive errors. The folding glasses can usually be folded at the bridge of the nose and the temple to reduce the space when stored or carried and are mostly used for making reading glasses.
Can night driving glasses prevent blue light?
Night driving glasses are called night vision goggles. Some night-driving glasses have anti-reflective coatings. Night driving glasses reduce glare by scattering and filtering blue light. Blue light is the shortest wavelength in the spectrum and is possible to cause glare when it enters the eye. The night driving glasses, available in colors from yellow to amber, filter out a lot of glare, and other light, and then make it difficult to see in dark conditions. But tests and studies have shown that night driving glasses don't improve night vision or help drivers see pedestrians faster than they won’t wear them.

What is a progressive lens?
Progressive multifocal lenses are lenses with different upper and lower powers for seeing far above and below for seeing near. The distance from the fixed far power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power. Compared with ordinary lenses, there are many advantages. The appearance of the lens is like a single vision lens, and the dividing line of the power change is not visible. Not only is the appearance beautiful, but more importantly, it protects the age privacy of the wearer, and there is no need to worry about revealing the age secret due to wearing glasses.
Since the change of the lens power is gradual, there will be no image jump. It is comfortable to wear and easy to adapt. So it is easy to be accepted. Because the degree is gradual, the replacement of the adjustment effect is gradually increased according to the shortening of the short distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue. Clear vision can be obtained at all distances in the visual range.
Such a pair of glasses meets the use of long-distance, near-use and various distances in the middle at the same time. It is especially good news for teachers, doctors, music workers, and computer operators, because these people not only need to see far and near objects clearly, but most of the time they also need to be able to see middle distance objects such as blackboards, piano scores, and computer screens. . This is not possible with any lens other than progressive lenses.
