Final answer:
Cataracts could be the condition indicated by spots in the vision.
Step-by-step explanation:
The spots discussed in the question could indicate the presence of cataracts. Cataracts are a clouding of the lens in the eye, which can lead to blurred or foggy vision and the appearance of spots. Other conditions mentioned in the options, such as presbyopia, glaucoma, and myopia, do not typically cause spots in a person's vision.
