So if they are so useful, why everyone who need two pairs of glasses not wear them? The answer is simple. High performance progressive lenses appeared in the meantime....

And then, why some of us wear bifocal lenses? ... Well I will answer this question in the next part, which simultaneously shows you whether the bifocal lenses are for you or not, so ....

When should you choose bifocals

Naturally you ask yourself: Is this kind of lens for me?

To get your answer think about where and when you need glasses, what are the distances to use them more.

If you use a lot of times the intermediate vision (for computer), you may not want bifocal eyeglasses because they don't have the intermediate diopters. But if you will use only the far vision and near vision, bifocal glasses are right for you.

Maybe it's easier to understand this if I give you some examples:

I had clients in our store who want bifocals because:

  • They most of the time read a lot (close vision), watch TV a lot (far vision) and they do not use the computer much
  • People which have tried progressive lenses and failed to adapt with them
  • People that had bifocals before

Here, you have some arguments pros and cons, to help you choose:

The pros of bifocals

  • First, you don't have to wear two pairs of eyeglasses 
  • The price is lower than for progressive lenses
  • They can be mounted in any frame
  • Can be manufactured from any known lens material (glass, plastic, polycarbonate)
  • Can be equipped with any coatings (anti-reflective, hardening, photochromic)

The cons of bifocals

  • Accommodation - there is an adjustment period with this type of lens 
  • They have only diopters for far vision and close vision, missing the intermediary (the use of the computer can be a problem)
  • Meanwhile have appeared the progressive lenses technologically superior to bifocals as a comparison is the difference between Blu-ray Disc and CD

To conclude

Bifocal eyeglasses are for you if you are in one or more of the next situations:

  • You're a person who has not many different daily activities, which not use continuously all vision distances (near, intermediate and far)
  • Want one and not two pairs of glasses but at a reasonable price
  • You are a heavy reader and TV watcher
  • Tried progressive lenses and could not get used to them or you find them too expensive
