Final answer:
Faulty eye movements or visual fatigue may indicate a need for vision therapy rather than eyeglasses or cataract surgery. Presbyopia is a common age-related condition where the lens loses focusing capability, often requiring reading glasses after 55. Astigmatism, caused by corneal irregularities, can be corrected with eyeglasses.
Step-by-step explanation:
Faulty eye movements or visual fatigue may indicate a need for vision therapy. These symptoms are not typically age-related changes, nor do they suggest a need for cataract surgery in most cases. Instead, they can be a sign that the visual system requires remediation through specific exercises or treatments.
VISION PROBLEMS
Vision problems like myopia, hyperopia, and presbyopia are examples of common issues that result in blurred vision. Presbyopia, in particular, occurs as people age and it represents a failure of the eyes to focus images on the retina due to the loss of elasticity in the lens and weakening of the muscles around it.
VISION CORRECTION
For those over the age of 55, the need for reading glasses often arises because their lens no longer focuses correctly due to presbyopia. Astigmatism, another vision issue, results from irregularities in the shape of the cornea and can lead to images appearing elongated. This condition can be corrected by eyeglasses with specialized lenses.
