Final answer:
Cataract surgery is not typically covered under a vision plan since it is a medical procedure often covered under health insurance. Instead, vision plans usually cover routine eye exams, corrective glasses, and contact lenses.
Step-by-step explanation:
A comprehensive group policy that includes vision care usually covers routine eye exams, prescription corrective vision glasses, and corrective contact lenses. However, it does not typically cover cataract surgery because this is considered a medical procedure and is usually covered under the medical portion of a health insurance plan.
Correcting vision problems like myopia and hyperopia can be done through corrective lenses or surgeries like LASIK.
In contrast, cataract surgery involves the removal of the clouded natural lens of the eye, which is then replaced with an artificial intraocular lens.
Routine eye exams are important for detecting diseases that could lead to vision loss and determining if vision correction is necessary.
While most common vision plans cover routine care and corrections, they typically separate medical procedures like surgeries from the vision benefits.
