viễn thị
Definition
Noun:
- Farsightedness (Hyperopia): A common vision condition where distant objects can be seen clearly, but close objects appear blurry. This occurs because light entering the eye is focused behind the retina instead of directly on it.
- Long-sightedness: An alternative term for the same condition.
Adjective (less common):
- Farsighted; Hyperopic: Describing a person who has this vision condition.
Usage Examples
Noun:
- Viễn thị thường là một tật khúc xạ bẩm sinh. (Farsightedness is often a congenital refractive error.)
- Ông ấy đeo kính để điều chỉnh chứng viễn thị. (He wears glasses to correct his hyperopia.)
Adjective:
- Một người viễn thị có thể đọc biển báo đường từ xa rất dễ dàng. (A farsighted person can read road signs from a distance very easily.)
Advanced Usage
- In a broader, metaphorical context, "viễn thị" can occasionally be used to describe a person or a plan with good long-term vision or foresight, though this usage is less common than the medical term.
- Nhà lãnh đạo viễn thị đó đã định hướng cho tương lai của công ty. (That farsighted leader charted the company's future.)
Variants and Related Words
- Viễn thị lão (Presbyopia): Age-related farsightedness, where the eye's lens loses flexibility, making it difficult to focus on close objects. While related, this is a different condition from hyperopia.
- Viễn thị lão thường bắt đầu xuất hiện ở tuổi trung niên. (Presbyopia usually begins to appear in middle age.)
Synonyms
