● Why choose the bifocal lenses?

 

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.

 

Bifocals have noticeable lines between the upper and lower portions but those in round-seg bifocals tend to be less conspicuous than those of executive and flat-top styles. ens without the visible lines, your best option is to use progressive lenses.

 

Older golfers have a special type of bifocals where the small round segment for near vision is placed in the outer lower corner of just one of the lenses. If the golfer is right-handed the seg is on the right lens and on the left if he is left- handed.
