Bi Focal Lenses

Bifocal Eyeglasses from An Optometrist in Fairfield

Most of us don't require bifocal lenses until we reach our 40s or 50s. That is because as we age, our eyes change and have less flexibility. In most cases, this shows up as an inability to see things up close, such as reading or working on a computer combined with difficulty with far away tasks such as driving or walking. This results in the need for bifocal lenses, which combines correction for individuals who are both near- and far-sighted. However, there are situations where a child, adolescent, teen, or young adult may need bifocals, such as if they struggle with the switch from looking close up to far away or if they have one near-sighted eye and one that is far-sighted. If you are looking for a family eye care optometrist in Fairfield, Frattoo Optometry is the place to go.


Why Do I Need Bifocal Glasses?

In situations where a patient is both near- and far-sighted, bifocal lenses will correct their vision in both eyes. However, some patients find that the only correction they need at first is for up-close work. In this case, most people choose to use reading glasses that can be purchased in their local drugstore without a prescription. But this type of glasses is only a temporary fix, and they will likely require prescription bifocals within a few years.

Types of Bi Focal Lenses

There are many options for bifocal lenses, and your optometrist will help you figure out the best choice for you and your lifestyle. The following will explain the different types available:


  • Progressive lenses are the most popular type. Essentially, a progressive lens combines three different prescriptions in one pair of glasses. It has a lens for up-close work, middle-distance work, and distance viewing. The progressive lens has a gradual change for each type of sight. These lenses are sometimes referred to as multifocal lenses.
  • Executive lenses have a distinctive line in the middle of the glasses to separate between distance and near vision. They have become somewhat extinct as most people prefer not to see the line between the two viewing fields.
  • Flat-top lenses are made with a small half-moon at the bottom of the lens.
  • There are other types of lenses, but most of them are no longer used since progressives came on the scene. Trifocals and blended and round seg lenses all provide different varieties of bifocal vision at one time.
