What are acetate glasses?
Acetate spectacle frames are the most common spectacle frames on the market. It has a light texture and good gloss, which is very popular among young men and women.

Unlike some plastic or metal frames, they can cause allergic reactions. However, you will find that acetate frames are usually more expensive than ordinary plastic frames. So what is the reason?
Acetate is one of the first synthetic fibers. It was not used to make glasses until the late 1940s. The higher the quality of acetate, the better the gloss and transparency. Not easy to burn is one of the biggest characteristics of acetate fiber. Also because of the non-combustibility of acetate fiber, this material can hardly be affected by ultraviolet radiation to change color, and can better maintain the gloss of the spectacle frame. Moreover, it is light and hard, and it is not easy to deform.
Why should children wear blue-light-blocking glasses?
Due to the short wavelength of blue light, the focus will fall in the front of the retina. In order to see clearly, the eyeball will be in a state of tension for a long time, causing visual fatigue. Studies have found that exposure to blue light at certain doses can damage epithelial cells on the surface of the eye, causing or aggravating dry eye. Harmful blue light has extremely high energy and can penetrate the lens directly to the retina, leading to the atrophy and death of retinal pigment epithelial cells. The death of light-sensitive cells will lead to vision loss.
Who need progressive lenses?
There is no limit to the degree of progressive multifocal lenses. Whether it is nearsightedness, presbyopia or moderate astigmatism, it can be worn, but not everyone can wear it. There are two types of progressive multifocal lenses on the market, one is hard and the other is soft. The main difference between the two designs is the length of the progressive channel. The rigidly designed progressive film has a short progressive path and relatively less peripheral aberrations. In order to ensure vision at various distances, fewer vertical dimensions are required. For example, a teenage progressive film belongs to this design, but because of its short gradual path, the gradation process is too short. Fast. Compared with the elderly, this design is more difficult to adapt; the soft design of the progressive film has a relatively long gradation channel and relatively large peripheral aberrations, but due to its long gradation channel, the gradation process is relatively smooth, which makes it easy to wear glasses It is suitable for people with poor adaptability.
If you are a person who is able and willing to accept new things, understand and adapt to the temporary discomfort caused by progressive addition lenses, we suggest that he can wear a pair, if he has severe hypertension, dizziness and other symptoms, or People who have misunderstandings about progressive lenses and are unwilling to adapt should not try them.

The perception of space has changed, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do strenuous exercise. When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing an object through the blurred vision area around the lens makes the object blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-use zone, the near-use zone, and the middle-distance zone to see objects.
The clear frame is paired with wire glasses.
Compared to traditional chunky glasses, gold-rimmed glasses have less color saturation, so they are almost skin-neutral. Gold-rimmed glasses and clear frames are similar in style but more decorative.

So, why are my progressive lenses blurry on sides? It can be caused by a lot of reasons, and we will list some of them.
The strength of progressive lenses is the factor that leads to initial peripheral blurriness. Progressive lenses tend to be blurry on the sides because each lens promotes three fields of vision. In addition, peripheral blurriness or haziness is a sensation that typically develops because more than one lens has been incorporated into one lens. The wearer also might feel as if he or she is moving from side to side.
After learning what may cause progressive lenses blurred, so how can you adapt to the progressive lenses? Therefore, in the following section, we will show you how to get used to progressive lenses.
Glasses Size - Bridge Width
The bridge width is the distance between two lenses, measured from the innermost layer of each lens. Finding the right bridge width will allow your sunglasses or glasses to be put properly on the bridge of your nose. The bridge of the nose is an essential element because even though the frame looks pretty attractive, it helps people see more clearly. The precise distance between the two lenses helps reduce the pressure on the eye, helping the nose, without putting too much pressure on the inside of the eye. The size of the eye and the size of the bridge is usually adjacent, sometimes separated by a square icon.
