Presbyopia意思

Presbyopia is a condition that affects the eyes as people age, typically beginning around the mid-40s. It is a natural part of the aging process and occurs when the lens inside the eye becomes less flexible, making it harder for the eye to focus on objects that are close up. As a result, people with presbyopia may experience difficulty reading or doing other close-up work, such as sewing or using a computer.

Presbyopia is not a disease and cannot be prevented, but it can be corrected with a variety of treatments, including reading glasses, bifocals, progressive lenses, contact lenses, and refractive surgery. The type of correction that is best for an individual depends on the severity of the presbyopia and the person's overall eye health and lifestyle.
