Final answer:
For baby boomers, wearing contact lenses may present difficulties due to issues with handling small items like lenses and increased instances of dry eyes, both related to age-related changes such as presbyopia.
Step-by-step explanation:
The cons for baby boomers wearing contact lenses primarily include difficulty handling small objects, such as the lenses themselves, and potential dry eye issues. As people age, they may develop presbyopia, a condition in which the eye's lens loses its ability to focus on close objects due to decreased elasticity and weakening of the controlling muscles. As a result, they often require reading glasses or other vision aids to see up close. Moreover, the ageing process can increase the risk of dry eyes, which can be exacerbated by contact lens wear. It's worth noting that there are benefits and drawbacks to different modes of vision correction, and what might be a con for one individual could be outweighed by the pros for another. For instance, while contact lenses can pose handling and dryness challenges, they do not increase the risk of eye infections when proper hygiene is followed, and they might be a preferable option over glasses for some people.
