EXPLANATION OF BIFOCAL LENS

- HYPEROPIA AREA

Use it when walking and looking at things from far distance.

- MYOPIS AREA

Meet various needs at close distance, clear and eliminate blurry.

  • Round top bifocals are further described by the width of the near segment, measured in millimeters (mm). The most popular RT bifocal is the RT-28, a round top bifocal with a near seg that is 28 mm wide.

Bifocal lens can be called a multi purpose lens. It has 2 different fields of vision in one visible lens. The larger of the lens usually has the prescription necessary for you to see for distance. However, this can also be your prescription for computer use or intermediate range, as you would normally be looking straight when you view through this particular part of the lens. The lower part, also called the window, typically has your reading prescription. Since you generally look down to read, this is the logical place to put this range of vision assistance.

RT LENS

The advantage of the RT bifocal lens

As people age, they may find that their eyes are not adjusting to distances as they used to. When people inch closer to forty, the lens of the eyes begin to lose flexibility. It becomes difficult to focus on close objects. This condition is called presbyopia. It can be managed to a large extent with the use of bifocals.

Bifocal (also can be called Multifocal) eyeglass lenses contain two or more lens powers to help you see objects at all distances after you lose the ability to naturally change the focus of your eyes due to age.
