Final answer:
Two changes in the older adult concerning eyes are the loss of focus in the cornea and lens, leading to blurry vision, and the elongation of the eyeball, causing images to focus in front of the retina.
Step-by-step explanation:
The two changes in the older adult concerning eyes are:
- Their cornea no longer focuses correctly, which can lead to blurry vision.
- Their lens no longer focuses correctly, which can also lead to blurry vision.
Additionally, the eyeball may elongate with age, causing images to focus in front of the retina, further contributing to vision problems.
As a result of these changes, many people over 55 often need reading glasses to help them see clearly up close.
