    II. Flat Top Bifocal Lens:

     

    • Bifocals in General

     

    Bifocals have the unique ability to give two lens powers so that you can see both near and far. The bottom portion of the lens is used for seeing up close like with reading or computer work. The top portion is for distance but some people do not need it so sometimes that portion has no prescription in it at all. It will vary with each person.

     

    • Flat Top 28 Bifocals

     

    Flat top 28 bifocals are still bifocals but a little different in how they are created. These lenses are also called straight top lenses and how they work is that they are a fused bifocal. These have a D-shaped near segment that has a 90 degree rotation which makes the D face upwards. Another reason they are called flat-top 28 bifocals is that the near seg is 28mm wide, which makes it easy to remember. These are the most popular flat top bifocals.

    • How bifocal lens work?

     

    Bifocal lenses are perfect for people suffering from presbyopia- a condition in which a person experiences blurred or distorted near vision while reading a book. To correct this problem of distant and near vision, bifocal lenses are used. They feature two distinct areas of vision correction, differentiated by a line across the lenses. The top area of the lens is used for seeing distant objects while the bottom part corrects the near-vision
