Final answer:
Presbyopia is age-related farsightedness where the eye loses its ability to focus on close objects, typically becoming noticeable between ages 40 and 50, and is corrected with glasses or bifocals.
Step-by-step explanation:
The term that describes age-related farsightedness is presbyopia. Presbyopia is a vision problem that occurs as part of the natural aging process, where the eye gradually loses the ability to focus on close objects. This condition is believed to be caused by the lens becoming less elastic and the muscles controlling the lens weakening with age. Symptoms such as eyestrain and difficulty reading small print typically manifest between the ages of 40 and 50. Unlike hyperopia, which is a common form of farsightedness where images are focused behind the retina, presbyopia stems from the lens losing flexibility. Most people with presbyopia require corrective lenses, such as reading glasses or bifocals, as surgical options like LASIK do not address the issue of the lens's reduced elasticity.
The first signs of presbyopia, such as eyestrain, difficulty seeing in dim light, and problems focusing on small objects and fine print, are usually noticed between the ages of 40 and 50. Most older people with this problem use corrective lenses to focus on close objects, as surgical procedures to correct presbyopia are not as successful as those for myopia and hyperopia.
