视力

shìlì
At the A1 level, you only need to know that **视力 (shìlì)** means 'eyesight' or 'vision'. You can use it in very simple sentences to talk about your health. For example, '我的视力很好' (My eyesight is very good) or '我的视力不好' (My eyesight is not good). It is usually taught when learning body parts like 眼睛 (eyes). You might hear a doctor ask '你的视力怎么样？' (How is your vision?). At this stage, just remember that it is a noun and you use '好' (good) or '不好' (not good) to describe it. Don't worry about technical numbers or complex verbs yet. Just think of it as the 'power' of your eyes.
At the A2 level, you should be able to use **视力** in more practical contexts, such as visiting a doctor or talking about habits. You should learn the verb **保护 (bǎohù)**, which means 'to protect'. A common sentence would be '我们要保护视力' (We need to protect our eyesight). You might also learn that looking at a phone for too long is bad for your 视力. You can start using it with simple results, like '视力下降' (vision is going down/declining). This is useful for explaining why you might need glasses (眼镜). You should also recognize the word in school settings, as it is a common topic in health and lifestyle discussions.
At the B1 level, you can discuss the causes and effects related to **视力**. You should be able to explain *why* vision might decline, using words like '电子产品' (electronic products) or '压力' (pressure). You can use more specific verbs like **检查 (jiǎnchá)** for 'to check' and **恢复 (huīfù)** for 'to recover'. For example, '手术后，他的视力恢复了' (After the surgery, his vision recovered). You should also be aware of the term '视力表' (eye chart). At this level, you can start to distinguish 视力 from related words like '眼力' (discernment) and understand that 视力 is strictly about the physical ability to see clearly.
At the B2 level, you are expected to use **视力** in formal and semi-formal discussions. You might talk about public health issues, such as the '视力健康' (vision health) of a nation's youth. You can use terms like **矫正 (jiǎozhèng)** for 'correction' and **损害 (sǔnhài)** for 'damage'. You should be able to read articles about medical breakthroughs in vision care or government policies regarding eye health in schools. You can also use the word in the context of professional requirements, such as '视力要求' (vision requirements) for certain jobs. Your sentences should be more complex, perhaps using '由于...导致视力下降' (Due to... resulting in a decline in vision).
At the C1 level, you should have a nuanced understanding of **视力** and its place in broader linguistic contexts. You can discuss the technical aspects of vision, such as '裸眼视力' (uncorrected vision) versus '矫正视力' (corrected vision). You should be able to understand and use the word in academic or medical literature, discussing things like '视力疲劳' (visual fatigue) in the digital age or the impact of environmental factors on ocular development. You should also be very clear on the boundaries between 视力 and metaphorical terms like '眼光' or '远见', ensuring that you never use 视力 incorrectly in a figurative sense. You can engage in deep conversations about the social implications of widespread vision problems.
At the C2 level, your mastery of **视力** is near-native. You can use the term in highly specialized contexts, such as ophthalmological research or high-level policy debates. You understand the historical development of the term and its cultural significance in China, including the history of the national 'Eye Exercises'. You can use the word with precision in literary contexts, perhaps contrasting physical 视力 with spiritual or intellectual 'insight' (洞察力) for rhetorical effect. You are comfortable with all collocations, including rare or formal ones like '视力衰竭' (vision failure) or '视力普查' (general vision screening). Your usage is flawless across all registers, from casual slang to formal medical reports.
Pratique Exemplos Notas e dicas

视力 em 30 segundos

  • 视力 (shìlì) is a noun meaning vision or eyesight, focusing on the physical clarity of what one sees.
  • It is commonly used with verbs like 保护 (protect), 检查 (check), and 下降 (decline).
  • In China, it is a major health topic due to high myopia rates among students.
  • It is strictly literal; for metaphorical 'vision,' use words like 眼光 or 远见.

The term 视力 (shìlì) is a fundamental noun in the Chinese language that specifically refers to the physiological ability of the eyes to distinguish the shapes and details of objects at a given distance. It is the literal 'power of vision.' In a biological sense, it encompasses the clarity of the retinal image and the precision of the brain's interpretation of that image. When we talk about 视力, we are often discussing the health of the ocular system, the refractive state of the eye (whether one is nearsighted or farsighted), and the overall functional capacity of one's sight. In modern China, 视力 is a topic of intense public interest due to the high prevalence of myopia among the youth, making it a word you will encounter in medical, educational, and daily social contexts.

Physiological Aspect
Refers to the sharpness of vision, often measured using a Snellen chart or the E-chart common in China.
Social Aspect
Often used in discussions regarding health standards for certain professions, such as pilots or drivers.
Metaphorical Extension
While less common than '眼光' (insight), it can occasionally imply the physical capability to perceive details others might miss.

“由于长时间看电脑，他的视力明显下降了。” (Due to looking at the computer for a long time, his vision has clearly declined.)

Understanding 视力 requires looking at its components: 视 (shì) meaning 'to look' or 'vision', and 力 (lì) meaning 'power' or 'strength'. Together, they form the 'strength of looking.' This word is strictly a noun and cannot be used as a verb. You don't '视力' something; rather, you 'have' (有) good 视力, or your 视力 'declines' (下降). It is a neutral term, though in modern discourse, it is frequently associated with the 'protection' (保护) of one's eyes against the digital strain of the 21st century.

“飞行员对视力的要求非常高。” (The requirements for vision for pilots are very high.)

Medical Context
Used in '视力检查' (vision test) and '视力矫正' (vision correction).
Educational Context
Schools in China perform regular '视力检测' to monitor students' eye health.

The word also appears in various compound concepts. For instance, '裸眼视力' (luǒyǎn shìlì) refers to uncorrected vision (without glasses), while '矫正视力' (jiǎozhèng shìlì) refers to vision with glasses or contacts. This distinction is crucial in official documents and medical records. Furthermore, the concept of 视力 is deeply tied to the 'Eye Exercises' (眼保健操) that Chinese students perform daily, a cultural phenomenon aimed at maintaining good 视力 from a young age.

“多吃胡萝卜对保护视力有好处。” (Eating more carrots is good for protecting your eyesight.)

Using 视力 correctly involves pairing it with the right verbs and adjectives. As a noun, it typically functions as the subject or object of a sentence. Because it describes a physical capacity, it is often quantified or qualified by its quality. The most common verbs used with 视力 are 保护 (protect), 检查 (check/examine), 下降 (decline), and 恢复 (recover/restore).

Common Verb Pairings
保护视力 (Protect eyesight), 损害视力 (Damage eyesight), 测试视力 (Test vision).
Adjective Modifiers
视力良好 (Good vision), 视力模糊 (Blurred vision), 视力微弱 (Weak vision).

When describing someone's vision, you would say '他的视力很好' (His vision is very good) or '我的视力不太好' (My vision isn't very good). Note that you do not use '看' (look) to describe the quality of vision; you use '好' (good) or '差' (bad). If you want to talk about the process of vision getting worse, '下降' (xiàjiàng) is the standard formal term, while '变差' (biàn chà) is more colloquial.

“你应该定期去医院检查视力。” (You should go to the hospital regularly to check your vision.)

In formal writing, such as medical reports or academic papers, 视力 is often categorized. You might see '中心视力' (central vision) or '周边视力' (peripheral vision). In the context of technology, we discuss how screens affect 视力. For example, '电子产品对青少年的视力有负面影响' (Electronic products have a negative impact on the vision of teenagers). This sentence structure—[Subject] 对 [Noun] 有 [Influence]—is a classic way to use 视力 in a B1/B2 level sentence.

Another important usage is in the context of '矫正' (correction). If someone has poor vision, they might seek '视力矫正' (vision correction) through glasses, contact lenses, or laser surgery (激光手术). When talking about the results of such procedures, you would say '手术后，他的视力恢复到了1.0' (After the surgery, his vision recovered to 1.0). Here, the use of '到' (to) indicates the specific point of recovery.

“这种眼镜可以有效地矫正你的视力。” (These glasses can effectively correct your vision.)

You will encounter the word 视力 in several distinct environments in Chinese-speaking societies. The most common is the medical environment. At an eye clinic (眼科门诊) or an optician (眼镜店), the staff will constantly use this word. You'll hear '请看视力表' (Please look at the eye chart) or '你的左眼视力比右眼好' (Your left eye vision is better than your right eye). In these settings, the word is technical and precise.

At School
Teachers often remind students: '注意坐姿，保护视力' (Pay attention to your posture, protect your eyesight).
In Advertisements
Marketing for eye drops, supplements (like Lutein), and 'eye-protection' lamps (护眼灯) frequently use 视力 to appeal to health-conscious consumers.

The educational system is another major source. In China, students undergo mandatory physical exams (体检) every year, and 视力 is a key metric. Parents often discuss their children's 视力 with worry, as the academic pressure leads to long hours of study and potential myopia. You might hear a parent say, '我真担心孩子的视力，他作业太多了' (I'm really worried about my child's eyesight; he has too much homework).

“学校每年都会组织学生进行视力普查。” (The school organizes a general vision screening for students every year.)

In the workplace, especially for jobs requiring high physical standards, 视力 is a frequent topic. This includes the military (军队), aviation (航空), and even certain high-precision manufacturing roles. During recruitment, you might hear '视力达标' (vision meets the standard) or '视力不合格' (vision does not pass). Even for office workers, the term '视力疲劳' (visual fatigue) is a common complaint heard around the water cooler.

Finally, in news and media, you will see reports on the 'national vision health' (国民视力健康). Government initiatives often aim to '降低青少年近视率' (reduce the myopia rate among teenagers), and 视力 is the primary keyword in these reports. It is treated as a matter of national health and even national security, as it affects the pool of eligible military recruits.

Learners of Chinese often make specific errors when using 视力. The most frequent mistake is confusing it with related words like 眼睛 (yǎnjing - eyes), 视野 (shìyě - field of vision), or 视觉 (shìjué - sense of sight/visual). While '眼睛' is the physical organ, '视力' is the capacity of that organ. You cannot say '我的眼睛很差' to mean your vision is bad (though people might understand), the correct term is '我的视力很差'.

Confusing with '眼睛'
Wrong: 他的眼睛是1.5。 Right: 他的视力是1.5。
Confusing with '视觉'
视觉 refers to the whole visual system or aesthetic 'vision'. 视力 is just the clarity of sight.

Another common error is using the wrong verb for 'checking' vision. Learners might use '看' (look) or '观' (observe) instead of the correct 检查 (jiǎnchá) or 测试 (cèshì). For example, '我要看我的视力' sounds like you are literally trying to look at the concept of vision, whereas '我要检查视力' means you want to have your vision tested.

“错误用法：我的视力很看。 正确用法：我的视力很好。” (Common mistake: My vision is very look. Correct: My vision is very good.)

There is also a tendency to misuse 视力 in metaphorical contexts. In English, we might say 'He has great vision for the future.' In Chinese, you would use 眼光 (yǎnguāng) or 远见 (yuǎnjiàn) for this. Using 视力 here would make it sound like the person literally has sharp eyes and can see physical objects in the future, which is nonsensical. 视力 is almost always literal and physiological.

Lastly, be careful with the word order when describing vision loss. Some learners say '视力丢失了' (lost vision), which sounds like you dropped your vision on the street. The correct way to say you lost your sight is '失明' (shīmíng - become blind) or more formally '视力丧失' (shìlì sàngshī - loss of vision capacity).

To truly master 视力, one must understand how it differs from its synonyms and related terms. The most closely related word is 眼力 (yǎnlì). While 视力 refers to the physical sharpness of the eyes, 眼力 often refers to the ability to discern quality, authenticity, or subtle details—often translated as 'judgment' or 'discernment'. For example, an antique expert has good 眼力, but they might have poor 视力 and need glasses.

眼力 (yǎnlì)
Focuses on discernment, judgment, or the ability to spot something specific.
视觉 (shìjué)
The sense of sight. Used in terms like '视觉艺术' (visual arts) or '视觉效果' (visual effects).
视野 (shìyě)
Field of vision. Can be literal (what you see around you) or metaphorical (one's horizons/knowledge).

Another word is 目光 (mùguāng). This refers to the 'gaze' or 'look' in someone's eyes, or metaphorically, their 'vision' in terms of foresight. You would say '目光敏锐' (sharp gaze/insight), but you wouldn't use 视力 in that context. 视力 is the tool; 目光 is the expression or the direction of that tool.

“他的视力虽然不好，但他的眼力很强，一眼就能看出这幅画是假的。” (Although his vision is poor, his discernment is strong; he could tell at a glance that this painting is a fake.)

Then there is 眼界 (yǎnjiè), which literally means the 'boundary of the eye' but is almost always used metaphorically to mean 'outlook' or 'scope of experience'. When you travel, you '开阔眼界' (broaden your horizons). You would never say '开阔视力'. Understanding these distinctions prevents the 'uncanny valley' of language learning where a sentence is grammatically correct but semantically 'off'.

Finally, 见识 (jiànshi) is another related term meaning 'knowledge and experience'. While it contains the character '见' (to see), it is entirely about mental growth rather than ocular health. In summary, 视力 is the most 'medical' and 'physical' of all these terms, focusing strictly on the optical performance of the human eye.
