Final answer:
To compensate for poor peripheral vision, one may use corrective lenses, perform regular eye exercises, and increase situational awareness. Reading glasses are often needed by people over 55 due to presbyopia, where the eye's lens loses flexibility, affecting the ability to focus on close objects. Other vision problems like astigmatism and hyperopia also have specific corrections involving the shape and curvature of lenses.
Step-by-step explanation:
To compensate for poor peripheral vision, a person can make several adjustments such as using corrective lenses, engaging in regular eye exercises, and increasing overall awareness. Corrective lenses can help correct certain vision problems. For example, vision correction for someone with myopia (nearsightedness) may involve wearing glasses or contact lenses, which may need to be worn only for specific tasks or all the time depending on the severity. In the case of hyperopia (farsightedness), a convex lens is used to help focus on close objects. Regular eye exercises may improve the flexibility and focusing power of the eye, potentially helping with peripheral vision issues. Additionally, increasing overall awareness of one's surroundings can help a person better compensate for the areas where their vision might be lacking. It's important to consult with an eye care professional for personalized advice and potential vision therapy.Regarding why individuals over 55 often need reading glasses, it's because with age, the lens of the eye becomes less flexible, an issue known as presbyopia. This makes it harder to focus clearly on nearby objects, leading to the need for reading glasses which have specifically designed lenses to aid in reading and other close-up tasks.
Correction for Other Vision Problems : For conditions like astigmatism, eyeglasses with a cylindrically shaped lens are commonly used to counteract the irregularities. When a cataract-clouded lens is replaced with an intraocular lens, the person may achieve perfect distant vision but might still require reading glasses for near tasks. In cases where the cornea's curvature is reshaped to correct myopia, the goal is to change its curvature to a more optimal shape, while hyperopia correction often involves increasing the curvature.
