Question 1 of 20
The ability to see at a distance, in good light, does not diminish as a result of aging to the extent that other visual acuities do. Myopia, or nearsightedness, is more common to younger eyes, while presbyopia, or farsightedness, more commonly afflicts people as they age. The word presbyopia comes from Greek presbys, "old man," and opia, "eye," and names a condition in which, because the lens of the eye hardens slightly and loses elasticity as a person ages, one cannot as easily focus sharply on nearby objects. This condition leads to the familiar habit of lifting up one's glasses and bringing an object or reading material close to the face so that the eyes can more easily focus on it. The function of the lens is to accommodate different focal points so that sensory data can be correctly directed to the retina for interpretation into images by the brain. Corrective lenses, particularly bifocals or progressive lenses, adjust for the focal point aberration. In essence, they do the work that the eye can no longer do for itself.

In the context of the passage, what does 'accommodate' mean?

Rationale

In the context of the passage, 'accommodate' means to contain.

The passage discusses how the lens of the eye adjusts to focus on objects at various distances, which implies that it must 'contain' the necessary adjustments for different focal points. This aligns with the definition of 'accommodate' as it pertains to the lens's ability to hold or support the required adjustments for clear vision. A) "Arrange lodging for" refers to providing a place to stay or reside. This definition does not relate to the context of the passage, which focuses on the eye's ability to adjust focus rather than making arrangements for physical space or lodging. C) "Make allowances for" suggests adapting to circumstances or providing flexibility in response to a situation. While this might seem relevant in a broader context, it does not specifically capture the function of the eye's lens as described in the passage, which is more about the physical ability to focus rather than accommodating external conditions. D) "Excuse" means to overlook or forgive a fault or offense. This definition is unrelated to the concept of visual accommodation in the context of the eye, where the focus is on the lens's capability to adjust rather than absolving or excusing any visual shortcomings. Conclusion In the context of the passage, 'accommodate' primarily refers to the lens's ability to contain or support the necessary adjustments for focusing on objects at varying distances. While other choices present interesting interpretations, they do not align with the specific optical function described. Understanding this term is crucial to grasping how corrective lenses aid in restoring focus as the eye ages.
