They have blue light prevention, glare reduction, UV blocking, screen flicker prevention, electromagnetic ray blocking lens. The frames of these blue light glasses are made of TR90 material. They're twice as durable as plastic glasses. These blue-blocking glasses are made of reinforced metal hinges to ensure durability and avoid cracking.


What style of glasses is suitable for round faces?

The model of cat-eye glasses is niftier, with a more retro effect, so the fashion sense is strong, which can highlight the personality of the person. The glasses can modify the face, suitable for the girl with a round face. If you have a round face, it is recommended that you choose a pair of glasses with thick frames, which cover your face more and make your face look smaller visually. They fit all kinds of face shapes, especially round faces because they give people a visual impact, and they reduce the impression of face shapes.



Why do glasses with the same prescription feel different?

The style of the frame has changed. The structure of the new glasses and the old glasses (half-frame, rimless, full-frame) may be different, and the angle of the glasses may also be different, which will cause visual differences and the symptoms of dizziness after wearing the new glasses. If you used to wear rimless glasses or half-rim glasses before and switch to full-frame glasses, you will feel that his field of view is limited and you will feel a little uncomfortable when you see the edge of the frame. If you wear full-frame glasses before, you will feel the edge of the lens when you change to half-rim glasses. It's too bright to adapt. There is another situation, changing from a frame with a nose pad to a frame without nose pads. Because the distance between the lens and the eye has changed, the position of the nose pad has also changed, which directly affects the relative position of the optical center and the pupil, as well as the distance from the back vertex of the lens to the cornea, which naturally affects the visual difference. In this case, you can fine-tune the nose pads, or after a short-term adaptation, you can generally return to normal.

Normally, opticians do not want to change their original visual habits (to maintain visual continuity) and want to copy a pair of glasses with the same vision. When optometry, they must provide the used old glasses and their optometry record sheet for inspection. With personnel reference. Simply put, comfort is equal to habit. If you want new glasses to wear comfortably, you must keep your original habits. It's not just the reproduction of luminosity. If you don't wear suitable glasses often, you will feel uncomfortable once you wear them.


Round Glasses

While round glasses have been popular for the past few years, this season, metallic round frames from the '80s and 90s are getting more attention. These days, round glasses aren't just for Harry Potter fans. People add a sense of weirdness or fashion to their appearance. If you have an angular face and a chiseled chin, then round glasses are for you.



Is blue light blocking worth it?

There are two main problems with anti-blue glasses currently on the market. One is that the place to be prevented is not preventable, and the other is that people have color casts due to wrong protection and aggravate visual fatigue. Studies have shown that our eyes are the most intolerant of blue light in the 400-440 nanometer band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. However, the blue waveband of electronic products is between 450 nanometers and 490 nanometers, so most anti-blue glasses have little protection in this waveband. In addition, the blocking rate of anti-blue glasses is 20%~30% to achieve a good anti-blue light effect, but now the blocking rate of anti-blue glasses on the market has basically reached 80%~90%. All in all, these blocking blue light glasses cannot prevent the blue light in the 450-490 nanometer band, and their high blocking rate will also cause a color shift, which makes people more likely to have eye fatigue and headache.

In daily life, the intensity of blue light is low, not enough to cause damage to the fundus, so ordinary people do not need to wear anti-blue glasses unless they are working in extremely strong light conditions or working in special environments. To protect the eyes, it is more important for people to develop good eye habits. For example, wear a pair of suitable glasses and read insufficient light and at an appropriate distance. Avoid using electronic products for a long time. Take a break for 20 to 30 seconds every 20 to 30 minutes, and look at the distance regularly. If you have dry eyes while reading the electronic screen, remember to blink to 12 times per minute. It is best to wear sunglasses when outdoors.


Do blue light blocking glasses work?

Usually, blue light blocking glasses are yellowish, and this obvious color shift can cause serious visual fatigue. The aggravation of visual fatigue will not control myopia and will accelerate the progression of myopia. The most important thing is that some parents have the misconception that blue light blocking glasses can control myopia. If they allow children to use electronic products without guidance and control, myopia will definitely progress. During online classes, the best way to avoid the blue light damage of electronic products should be to relax their eyes between two classes. You can learn from the 20-20-20 rule recommended by the American Academy of Ophthalmology, which is to look at objects 20 feet away for at least 20 seconds for every 20 minutes. Also, you can take a break of 10-15 minutes between each online class. You can choose to look at the distance, play table tennis at home, or have fun with parent-child interaction. In this way, the tense shoulder and back muscles can be relaxed while the eyes are relaxed and rested. Not only can it prevent and control myopia, but it is also very helpful for improving the efficiency of learning. Teach children to blink their eyes more consciously when watching the electronic screen, and use a warm wet towel to heat the eyes during rest. A humidifier can be used at home to increase the humidity of the surrounding environment. This can effectively prevent dry eyes caused by looking at the electronic screens for a long time.



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.
