The eye is able to view nearby and far off objects with ease because of the action of ciliary muscles which adjust the focal length of the eye thereby adjusting the power so that the image is always formed on the retina.
This ability of the eye is called power of accommodation.
Ciliary muscles are made of protein and as we get older, the muscles begin to weaken.
If the muscles are weak they wont function properly resulting in a fixed or slightly variable focal length of the eye. The eye begins to loose its power of accommodation.
That's why older people need spectacles and cannot see properly without them.
As people age, the lenses in their eyes become less flexible, making it harder to focus on nearby objects, a condition known as presbyopia. Additionally, the muscles that control the size of the pupil and the amount of light entering the eye weaken with age, leading to reduced ability to see in low light. Other age-related changes, such as a decrease in tear production, can also contribute to vision problems in older people.

Fluid intelligence generally decreases with age due to changes in the brain's structure and function, such as decreased neural plasticity and processing speed. Additionally, age-related factors like cognitive decline, slower information processing, and reduced working memory capacity can impact fluid intelligence. Lifestyle factors, such as physical activity, mental stimulation, and social engagement, can help preserve fluid intelligence to some extent.
