Bifocals & Trifocals

Bifocals & Trifocals  

Clear vision at every distance—without switching glasses.

Why Choose Multifocal Lenses?  

As we age, our eyes naturally lose the ability to shift focus between near and far objects. This condition, known as presbyopia, typically begins in your 40s and can make everyday tasks—like reading a book, checking your phone, or driving—more difficult.

Multifocal lenses like bifocals and trifocals are designed to solve this problem by combining multiple prescriptions into a single lens. They allow wearers to see clearly at different distances without needing to switch between pairs of glasses.

These lenses can also benefit younger individuals with focusing or eye teaming challenges, and may even help manage myopia progression in children by reducing near-work strain.

Understanding Presbyopia  

Presbyopia is a natural part of aging. Over time, the lens of the eye becomes less flexible, making it harder to focus on nearby objects. Common symptoms include:

  • Difficulty reading fine print  
  • Eye strain or headaches during close-up tasks  
  • Trouble seeing in low light  
  • Holding objects farther away to see clearly

While presbyopia isn’t preventable, multifocal lenses offer a practical solution to restore clarity and comfort.

What Are Bifocals?  

Bifocals contain two distinct lens powers—one for distance vision and one for near vision. They’re ideal for people who need help seeing both faraway and close-up objects.

How They Work:  

  • The upper portion of the lens is for distance tasks like driving or watching TV.  
  • The lower segment is for near tasks like reading or sewing.  
  • Lens segments may be shaped like a half-moon, circle, rectangle, or full bottom half—depending on your prescription and preferences.
  • Bifocals are a time-tested solution, originally popularized by Benjamin Franklin, and remain a reliable choice for many wearers today.

What Are Trifocals?  

Trifocals expand on bifocals by adding a third lens power for intermediate vision—typically at arm’s length. This makes them especially useful for tasks like working on a computer or reading a dashboard.

How They Work:  

  • Top segment: Distance vision  
  • Middle segment: Intermediate vision (e.g., screens, gauges)  
  • Bottom segment: Near vision (e.g., books, phones)

Trifocals offer a more complete visual solution for people who need clarity across multiple zones throughout the day.
