Classification
Nouns denoting natural processes.
Examples
- As people age, they often experience presbyopia, a common vision problem that makes it difficult to read or perform other tasks that require near vision.
- Presbyopia typically begins in the early to mid-40s and results from the gradual thickening and loss of flexibility of the lens inside the eye.
- After the age of 45, many people start to notice the effects of presbyopia, such as having to hold reading materials farther away to see them clearly.
- Presbyopia is a refractive error that occurs when the lens of the eye loses its ability to focus on close objects, causing blurry near vision.
- Correcting presbyopia usually involves wearing reading glasses, contact lenses, or undergoing refractive surgery to restore near vision.
