What is Presbyopia?

Presbyopia, also known as 老花, is a physiological insufficiency of accommodation associated with the natural aging of the eye. The term “presbyopia” is derived from a Greek word meaning “old eye.”

It is a normal part of the aging process and typically begins around the age of 40. You may notice that you hold your smartphone or reading materials, such as books, magazines, or newspapers, farther away to see them clearly. If you do not correct presbyopia, you may be bothered by headaches and eye strain.

Presbyopia can be corrected using single-vision lenses or specialized spectacle lenses, such as bifocals or multifocal/progressive lenses. These options not only address presbyopia but can also correct other refractive errors, including myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism.

Single-vision lenses are designed to correct only one distance—in this case, near vision.

Bifocal lenses, while effective for both distance and near vision, are less commonly used today because they omit the intermediate zone, limiting their versatility.

Multifocal or progressive lenses, on the other hand, offer a seamless transition between distance, intermediate, and near vision, making them a more practical and popular choice for individuals with presbyopia.

With advanced technology, various designs of progressive lenses are now available to suit different needs. Contact us at 8826 1212 for more information.
