II. Features

 

● Why need the bofical lenses?

 

The aging process includes changes in vision that makes everyday reading more difficult than usual because of the loss of one’s ability to focus naturally. This condition is called presbyopia. It is often relieved by wearing special reading glasses. People who have been wearing prescription eyeglasses because of nearsightedness or farsightedness will need bifocals or eyeglasses with two different lens powers to help them see objects at different distances.

Bifocals have two different lens powers that aid in seeing objects at various distances once the  aging  process reduces your ability to do so.  These are  usually prescribed to adults older than 40 years,  although some children and younger  adults may also  need them for focusing problems,  which strain the eyes while reading.

● The advantages of the bifocal lenses.

 

Some presbyopes opt for progressive multifocal lenses, which gradually change powers from the top portion to the bottom of the lens, without lines to separate them. However, conventional bifocals offer some advantage over progressive lenses, such as providing wider lenses for computer work and reading compared to progressive lenses. Special purpose bifocals are also available for computer work and other tasks requiring powerful near and intermediate vision.
