kính cận

Friendly

The Vietnamese word "kính cận" refers to "near-sighted glasses" or "short-sighted glasses." These are special glasses that people wear to help them see things clearly when they are close to them, but they may struggle to see things that are far away.

Basic Explanation:

• Meaning: "Kính cận" is used for glasses that correct nearsightedness (myopia). When someone has myopia, they can see nearby objects well but have difficulty seeing distant objects clearly.

Usage Instructions:

• You use "kính cận" when talking about glasses that help with seeing things up close. For example, if someone needs glasses to read a book but struggles to see a sign across the street, they might need "kính cận."

Example Sentence:

• "Tôi cần mua một cặp kính cận vì tôi không nhìn thấy rõ khi lái xe." (I need to buy a pair of near-sighted glasses because I can't see clearly when driving.)

Advanced Usage:

• In a more advanced context, you might discuss the reasons for needing "kính cận," such as spending too much time looking at screens or reading. You could also mention different types of "kính cận" that have specific features, like anti-reflective coating or blue light blocking.

Word Variants:

• Kính: This means "glasses" or "spectacles" in general.
• Cận: This means "near" or "close," referring to the ability to see nearby objects.

Different Meaning:

• The term "kính cận" is specific to short-sighted glasses. It does not refer to other types of glasses, such as those for far-sightedness (which would be "kính viễn" in Vietnamese) or reading glasses.

Synonyms:

• There are not many direct synonyms for "kính cận," but you may hear "kính mắt" (eyeglasses) used in a more general sense. However, "kính cận" specifically refers to glasses for nearsightedness.
