老眼 refers to a common vision condition that typically affects older adults, characterized by difficulty focusing on close objects. This condition occurs due to the natural aging process of the eye, where the lens becomes less flexible, making it harder to adjust focus. People with 老眼 may find activities like reading or sewing challenging without the aid of reading glasses. It usually begins around the age of 40 and can progress over time. Regular eye examinations can help manage this condition and ensure proper vision correction.
