How near vision spectacles work

Near vision spectacles work by making text or objects look larger (magnified). The power (strength) of the lens determines how much bigger text or objects will look.

There are different types of near vision spectacles. This module covers near vision spectacles with:

  • A magnification power range between +1.00 (weakest) to +3.00 (stronger).
  • Sağ və sol linzada eyni güc.

Near vision spectacles, which are two glass lenses held in a simple frame.

  • Standard near vision spectacles are ready-made with standard powers. The right and left lenses are the same power. They are usually just for people with near vision problems in older adults (presbyopia).
  • Prescription spectacles are prepared individually. They are prescribed after a full eye exam, by a person trained to do this. Prescription spectacles help people with different types of refractive error including distance vision problems (myopia), near vision problems (hyperopia) and astigmatism.

The different parts of near vision spectacles

Near vision spectacles have two main parts:

  • Linza - insanların baxdığı hissədir.
  • Çərçivə - buraya daxildir:
    • Halqalar - linzaları  yerində saxlayırlar.
    • Körpü - iki halqanı birləşdirir və şəxsin burnunun üstündə oturur.
    • Nose pads, which are small plastic pieces that sit on either side of the person’s nose. They keep the spectacles in a comfortable position.
    • Şəxsin başının hər tərəfinə və qulağına qədər uzanan qulaqardılar.
    • The hinge, which allows the spectacles to be folded when not in use.

Çərçivənin ölçüləri istehsalçıdan asılı olaraq dəyişir.

Geniş yayılmış ölçü variantlarından bəziləri aşağıdakılardır:

  • Linzanın diametri
  • Körpünün eni
  • Qulaqardıların uzunluğu

Some spectacles may have these measurements marked on the inside of the temple.

Near vision spectacles showing the temple length which is from one end of the flexible arm to the other end. The bridge width is the measurement of the piece that sits above the nose, and the lens diameter is the width of the lens.
