lähinägemise

Lähinägemine, also known as presbyopia, is a natural aging process that affects the eyes' ability to focus on close objects. It typically begins to occur in people over the age of 40 and progresses over time. The lens inside the eye, which helps to focus light on the retina, gradually loses its flexibility. This reduced flexibility makes it harder for the eye to change focus from distant objects to near ones.

Symptoms of lähinägemine include difficulty reading small print, needing to hold reading material at arm's length, experiencing headaches or eye strain after reading or close work, and blurred vision at normal reading distances. It is important to note that lähinägemine is not a disease but a normal physiological change. It affects most people as they age, regardless of whether they have previously had vision problems.

There are several ways to correct lähinägemine. Reading glasses are a common solution, available over-the-counter or through a prescription. Bifocal or progressive lenses in eyeglasses can correct both near and distance vision. Contact lenses, such as bifocal contacts or monovision contacts (where one eye is corrected for distance and the other for near), are also an option. In some cases, refractive surgery can be performed to address lähinägemine. Consulting an eye care professional is recommended to determine the most suitable correction method.
