What lenses are best for short-sighted glasses?
Choosing a pair of glasses for short-sightedness requires a combination of many factors. It is not easy to determine which lens is the best. The following are some key considerations: 1. ** Refractive Index and Abbe Number **: - Common lenses have a refraction index of 1.50, 1.56, 1.60, 1.67, 1.7, 1.74, etc. Usually, the higher the refraction index, the thinner the lens of the same degree. However, you can't just pursue high refraction index when you wear glasses, because the Abbe number of low refraction index lenses may be higher. The Abbe number reflected the degree of dispersion of the lens. The higher the value, the less obvious the rainbow edge phenomenon. You can check the Abbe number of your lens through a specific method. For example, if you find the icon of the bucket, you can keep your phone still and shake your head while staring at the logo. If you find that the dispersion of the lens changes greatly when you turn it, it means that the Abbe number is low and the dispersion is high. You may need to change the lens. 2. ** Material of lens **: - Nowadays, most of the lenses were made of resin, and the common basic materials were PR- 39 (Refractive Index 1.5/Abbe Number 58) and its variants such as MR - 8 (1.60/41), MR - 174 (1.74/32), KOC55 (1.552/35), and KP- 60 (1.60/33). In theory, the higher the index of refraction and Abbe number, the better. However, the higher the index of refraction, the lower the Abbe number. Under the same raw materials, the index of refraction and Abbe number of different manufacturers were the same. Some well-known domestic lens brands use imported raw materials. 3. ** Lenses coating technology **: - The coating could make up for the lack of raw materials, such as improving impact resistance, wear resistance, anti-reflection, pollution resistance, anti-fog and other properties. However, there was currently no testing agency that gave data on which coating technology was stronger. It was recommended to consider coating according to their own needs within the same brand. 4. ** Lenses shape **: - Spheric lenses had basically been eliminated. Among aspheric and double-aspheric lenses, double-aspheric lenses had less distortion and less distortion. If the price difference between aspheric surfaces and double aspheric surfaces within the same brand is not large, you can choose double aspheric surfaces. If the difference is large, aspheric surfaces can also meet the demand. 5. ** Domestic and imported lenses **: - Not all imported lenses were better than domestic lenses. Many domestic lenses were made of imported raw materials. When the lenses were matched accurately, the experience of using domestic high-end brand lenses was not inferior to imported lenses. However, high-quality raw materials were monopolized overseas, and it was easier for large factories to obtain high-quality raw materials. 6. ** Price of lenses **: - If an adult's glasses only pursued clarity and comfort, they could be matched with good lenses for about 300 yuan. Of course, there were also low-cost lenses, but the quality and experience might not be guaranteed. If you were looking for branded lenses, you would need to make more comparisons.
How about the lenses of the bright moon glasses?
Bright Moon lenses had the following characteristics: 1. Strengths 1. ** product innovation and research and development ** - Since its establishment, Mingyue lenses had attached great importance to innovation. In 2008, its self-developed super-tough lenses obtained a national invention patent. In 2014, he successfully developed a 1.71 index lens, breaking the curse of high refraction and high dispersion. 2. ** Material supply and cooperation ** - Cooperating with Mitsui of Japan and KMC of South Korea to establish the world's leading lens raw material R & D and production center, it is one of the few lens companies in the world to achieve self-reliance in raw materials. The material of the KP lens was developed and produced by a joint venture. The quality was stable and the safety was high. 3. ** Series of product features ** - ** Film Layer ** - There was a clear vision composite film (18-layer coating) and a celestial vision A6 film (20-layer coating). The celestial vision A6 film had the advantages of being easy to clean and anti-oil compared to the clear vision composite film. - ** Special lens material and series ** - The super durable lenses were very hard and resistant to impact. They were the first choice for frameless glasses and could also be used for sports lenses. - The MC series was the Bright Moon Ace series. It had high light transmission, high Abbe number, and high degree of reproduction. The overall effect was better. The 1.71 index of refraction of the PM lens is cost-effective for people with 500 - 900 degrees, but you should pay attention when choosing the frame. If the frame is too large, it may be blurred when you turn your head or look at the edge. - The 1.71 series of lenses had unique advantages. Compared to other lenses of the same type, the Abbe number was higher, the dispersion was lower, and the image was clearer. It was a cost-effective choice for people with high nearsightedness. - ** Blue light protection technology ** - It adopted the double effect of "lens film reflection + base material added with anti-blue light factor" to prevent blue light. While effectively blocking high-energy harmful blue light, it ensured that the beneficial blue light passed through without affecting other visible light, so that the eye protection was not biased. However, its anti-blue light lenses had a darker base color and might not be necessary for the average person, but heavy users of mobile phones and computers could consider it. 4. ** Value for Money ** - Regular lenses had a high cost-performance ratio. There were many customized products in the design of the lens base material, and the price was controlled within a reasonable range with a number of patents. 5. ** Market performance ** - Its products were sold in more than 30 countries and regions. From 2017 to 2020, its revenue and net profit had increased significantly. In 2021, it was listed on the Growth Enterprise Market of the SZX, becoming the first China brand lens manufacturer to enter the A-share market. ** 2. Deficiency ** - The unconventional series was more expensive, and custom lenses were more expensive than ordinary brands. For example, the price of 1.74 index lenses was twice that of 1.71. Its children's prevention and control series had a micro-structural design, but the number of buyers was small.
A good novel for short-sighted people
I recommend a few novels to everyone. Super Golden Right Eye was a novel about urban life written after himself. The main character, Li Zhuihua, had lost his sight in his right eye and miraculously regained his sight. He also had a super right eye because of the mysterious coffin and the light.

Why are Korean stars not short-sighted?
This statement was wrong. In fact, many Korean stars were myopes. For example, the well-known actress Song Hye Kyo mentioned wearing glasses or contact lenses in many programs. The actress Shin Min 'er was also myopes. While pursuing fashion, she also had to consider the combination of glasses to see things clearly and appear fashionable. Park Canlie once wore contact lenses when attending an event, but he couldn't see the question board clearly. He was ridiculed by netizens whether the degree of nearsightedness had worsened. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Who is the heroine of the novel that deliberately short-sighted?
He recommended a few great novels. "Demon Hunting: From the Year 2271 onwards" was a futuristic sci-fi novel written by Seven Colored Antlers. The main character, Geng Changlin, was extremely powerful. He controlled a lot of power and could even extract the enemy's things to forge a throne. "Carefree Doomsday" was a science fiction space doomsday novel created by a bit of shortsightedness. Cong Lu transmigrated from the cultivation space to the doomsday novel and wanted to get rid of the tragic ending of the female supporting character. "The Blind Husband" was an ancient romance novel written by Ci Wei. The female protagonist was reborn. Her previous life was very miserable. After her rebirth, she had to walk the road of Kangtai. I strongly recommend "Her Left Eye Is Unusual", a suspense adventure novel written by Shu Jiao. The female protagonist could see ghosts with her left eye. The story revolved around the growth of the female protagonist. The series of supernatural cases exposed the darkness of human nature. The female lead's personality was superb. She was not a saint and was decisive. Although some of the plots were controversial, such as emphasizing the female protagonist's independence and distrust of her partners, the overall rhythm and ability upgrade settings were good. At the beginning of the story, the female protagonist was caught in a death cycle by a mistress. After rebirth, she began to kill ghosts and demons. The book was slow to read, so it was recommended to start reading from chapter 40. The later it was, the more exciting it would be. There was also "The Blind Girl in the End of the World", written by Kapok Blooming. QQ. The blind girl, Ye Tong, was extremely tough in the end of the world and did not allow anyone to take advantage of her. These books are all very interesting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why are some people who often read novels online not short-sighted, but some people are easily short-sighted!
This question could be answered from many angles. 1. Genetic factors: The occurrence of nearsightedness is related to genetics. If both parents are nearsighted, the risk of children suffering from nearsightedness will increase. If there was a history of nearsightedness in the family, the possibility of it being passed down to the next generation would be greater. 2. environmental factors: long-term close eye use is one of the main reasons for nearsightedness. If you often read novels online, your eyes would need to stare at the screen for a long time. The brightness, contrast, and color of the screen might not be suitable for your eyes, resulting in excessive strain and fatigue. In this case, even if one was not usually short-sighted, one might gradually develop short-sightedness. The physiological structure of the eyes: Some people may be born with healthier eyes and better visual functions. Their eyes may be sharper and better able to adjust their focus and visual perception. These people wouldn't be short-sighted even if they read novels online for a long time. It should be noted that even if some people are not short-sighted, they should not use their eyes at close range for a long time, especially the computer screen should not be less than 20 inches (50 cm). Every hour, they should rest for 10-15 minutes away from the computer screen for eye exercises and other eye exercises. In addition, it is also very important to have a regular visual examination. Prompt detection and treatment can effectively alleviate vision problems.
The best domestic anti-control lenses
Some of the recommended domestic anti-control lens brands included Mingyue lenses. Brightmoon's Easy Control series (including Easy Control 1st generation and Easy Control Pro 2nd generation) was a good choice. Easy to control the defocusing of the second generation of the Pro's microlenses. It uses an exclusive 3D internal carving process to engrave 1,295 three-dimensional microlenses inside the lens.(There are more than 200 more than Star Interesting Control). The arrangement of baby's breath to increase the defocal area helps to control the stability of the degree of myopias. At the same time, the original "shell-shaped" visual area guarantees the comfort of wearing. Moreover, it has an advantage in price compared to foreign brands such as Zeiss Paradise, Heuer New Music, and Essilor Star Interesting Control. The price range covers about 1500 - 3000 yuan, and the main price band is more than 2000 yuan. In addition, New Tianhong was also a domestic brand worth considering in terms of child prevention and control lenses (defocused lenses). Its quality control was more reassuring. Mikibobo lenses ranked in the top three among domestic lens brands, but there was no more information to show its unique advantages in prevention and control lenses.
Impetuous, anxious and short-sighted are the taboos of writing novels
Impulsiveness, anxiety, and shortsightedness were all taboos to avoid when writing a novel. A novelist needs to remain calm, patient, and focused in order to create characters and plots with depth and complexity. At the same time, they also need to recognize that the novel is a creative art form that requires constant thought and adjustment. Impatience and anxiety often make novelists feel uneasy and distracted, affecting their performance and creativity. A lack of patience and concentration can also cause novelists to miss details and make their work rough and incomplete. In contrast, shortsightedness meant that novelists only focused on immediate interests and ignored long-term writing goals and the quality of their works. This mentality would cause novelists to write works that lacked depth and content and were not able to express true feelings and thoughts. Therefore, as a novelist, you need to remain calm, patient, and focused, constantly improving your creativity and writing skills, while paying attention to the quality and value of the work. Only in this way can you create excellent novels.
The novel recommended by the female protagonist is slightly short-sighted
There were a few female protagonists in modern romance novels who were slightly short-sighted. Among them," Young Master Si's Girlfriend Is A Little Nearsighted " and " I'll Guard You in the Palm " were two recommended novels. These novels described the female protagonist's nearsightedness, but she did not wear glasses. Other than that, there was no other recommended information about the female protagonist's slight short-sightedness.

Good short-sighted novels are recommended for boys to read
I recommend Invincible with Eyes by Chaos Fruit. The protagonist Qin Sheng's right eye mutated after he was electrocuted in his third year of high school. He could see the truth of murder cases, martial arts masters, ancient treasures, terrifying monsters, and even disappeared civilizations, sunken continents, and flying gods. His right eye was special, and he had accidentally obtained a cultivation method. He grew taller and more handsome, and started a new life. The protagonist had extraordinary luck and had an upright character. The results of this book were not bad. The cheat setting was novel, and it was different from the common eyes that looked at the future. Its recommendation index was four stars. " Super Golden Right Eye " was not bad either. The author was chasing after himself. The protagonist, Li Zhuihua, had lost his sight in his right eye and regained his sight. He had become a super golden right eye that could see through things, move objects, and have more functions. It was easy for him to appraise treasures, gamble stones, and see a doctor. "Five Hu Beacon Smoke," created by the infantry captain. The protagonist traveled to the Eastern Jin Dynasty and turned the tide during the chaos of the Five Kingdoms. However, some readers commented that the protagonist, the Virgin Mary, and so on, should be read with caution. The Free and Unfettered Way of Quick Wear was superb. The author was Xie Qing. The male protagonist, Chang Li, quickly traveled through different worlds. There was no strategy. It was a novel from the perspective of a male protagonist without a CP. The male protagonist was cold and powerful. Although there were some shortcomings, he was very special. He quickly traveled through different worlds. His recommendation index was four stars. There was also " God-grade VR Glasses " written by Little Butt. The VR glasses allowed Lin Feng to materialize the things in the game into reality, but it was a little long-winded. The author had given up, so he could read it when he was free. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
