Final answer:
Bifocals are the most common treatment for presbyopia, which is an age-related condition where the eye loses its ability to focus on close objects.
Step-by-step explanation:
The condition being described is presbyopia, which is a common vision problem associated with aging that results in difficulty focusing on close objects. The most common treatment option for an older adult with presbyopia experiencing errors in far and near vision is C) Bifocals. Bifocals are corrective lenses that have two distinct optical powers to help individuals see clearly at different distances. While eye surgery, hard contact lenses, and lens implants are potential treatments for various vision problems, bifocals are generally the first recommended and most widely used solution for presbyopia.
It's important to note that surgical procedures like LASIK can correct distant vision, but individuals with presbyopia will likely still require reading glasses to see up-close details clearly due to the loss of accommodation power in the eye. Presbyopia is corrected with converging lenses, which add power for close vision, thereby allowing the patient to focus on small objects or fine print that they previously found challenging.
