What is another word for presbyopia?
Pronunciation: [pɹɪsbɪˈə͡ʊpi͡ə] (IPA) 
Presbyopia is a common age-related eye condition that affects the ability to see objects close up. There are several synonyms for presbyopia, including "aging eye," "senile sight," "long-sightedness," "farsightedness," "old sight," and "middle-aged blur." Presbyopia is caused by the hardening of the eye's lens, which makes it difficult to focus on objects up close. It typically affects people over the age of 40 and is a natural part of the aging process. Many people with presbyopia use reading glasses or bifocals to help improve their close-up vision. Other treatment options include contact lenses or corrective surgery such as LASIK.
