What are the benefits of recycling old glasses?

Recycling old glasses contributes to sustainability and reduces waste. It is a way to give charity in addition to giving money. It can be able to teach children the importance and impact of philanthropy.

How many degrees of myopia do I need to wear glasses?

Students are the most nearsighted because they need to read and study every day. Many people have myopia during their student days. During the physical examination, everyone will check their eyesight first. Generally speaking, if the visual acuity is lower than 0.6, it means that you may be near-sighted to 0 degrees. At this time, you need to go for optometry to see the specific vision situation and see if you need to wear glasses. If the visual acuity tested exceeds 200 degrees, you must wear glasses at this time. If you do not wear glasses, your vision will be greatly affected, and the degree of myopia will rise quickly. For this reason, you must wear glasses in time to correct your vision. If the degree of myopia does not exceed 0 degrees, this is pseudo-myopia and does not require glasses. However, you should always take care to protect your eyes, avoid staring at things at close range for a long time, and don't let your eyes get too tired, so your vision will slowly return to normal.


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.



The main parts of glasses

1. Spectacle lenses

One of the most important accessories for glasses is spectacle lenses. Due to the increase in myopia patients, the demand for spectacle lenses is also very large, but the prices of spectacles on the market are also uneven.

Generally, the crystal stone materials are very safe and reliable, and we can choose carefully.

2. Spectacle frame

Another important figure in eyeglasses accessories is the frame. For those who like lightweight glasses, it is more appropriate to choose ultra-light frames or half frames. However, the frame must have durable and play a good role in maintaining the lens, otherwise, it will lose the meaning of the frame. Of course, the temples are also a part of the frame. There are also nose pads for glasses accessories. Many people have more requirements for nose pads. Generally, they choose soft ones that are not easy to press on the bridge of the nose.
