Presbyopic
Presbyopic
Presbyopic (/prɛzbiˈɒpɪk/), derived from the Greek words "presbys" (meaning "old man") and "ops" (meaning "eye"), is a condition associated with the aging process of the eye. It is characterized by the progressive loss of the eye's ability to focus on close objects.
Definition
Presbyopia is a natural, often annoying part of aging. In presbyopia, the eye's lens, which is normally flexible, hardens, making it more difficult to focus on close objects. This condition typically becomes noticeable in the early to mid-40s and continues to worsen until around age 65.
Symptoms
Symptoms of presbyopia include difficulty reading small print, having to hold reading material at arm's length, headaches, and eye strain.
Causes
Presbyopia is caused by a hardening of the lens of the eye, which occurs with aging. As the lens becomes less flexible, it can no longer change shape to focus on close-up images. As a result, these images appear out of focus.
Treatment
Treatment for presbyopia includes wearing corrective glasses or contact lenses, undergoing refractive surgery, or getting lens implants for presbyopia.
