What is a key characteristic of presbyopia?

Presbyopia is primarily associated with a gradual loss of the eye's ability to focus on nearby objects, which typically occurs with aging. A key characteristic of this condition is the difficulty reading fine print, as the lens of the eye becomes less flexible and unable to change shape effectively to focus on close-up text. This characteristic manifests in challenges like needing to hold reading materials farther away to see them clearly, which is a common experience for many individuals as they age.

While the other options mention issues that can affect elderly individuals, such as difficulty hearing or controlling movement, these do not describe the specific visual challenges associated with presbyopia. Difficulty writing may be related to other physical or cognitive issues, but it does not directly correspond with the changes in vision that define presbyopia.
