Prescription Bifocal Glasses

Prescription bifocal glasses are designed for people who need help with both distance vision and close-up tasks. They combine two prescription areas within the same lens, making it possible to use one pair of glasses for reading, general daily use and seeing clearly at longer distances.

For people who currently switch between everyday glasses and prescription reading glasses, bifocals can provide a more convenient option by bringing both corrections into one pair.

At Buy New Specs, we offer bifocal lens options for customers who prefer a clear separation between distance and near vision.

How Prescription Bifocal Glasses Work

Bifocal lenses contain two distinct prescription zones.

The upper part of the lens is usually used for distance vision, while the lower section is designed for near tasks such as reading or looking at smaller details.

This is different from single vision lenses, which provide one prescription across the whole lens. Bifocals combine two main viewing ranges in one pair of glasses.

The near-vision section is usually visible within the lens. Some wearers prefer this clear division because it makes the distance and reading areas easy to identify.

Why Choose Bifocal Lenses

Prescription bifocal glasses can be useful for people who regularly move between distance and near tasks during the day.

Instead of carrying two separate pairs, the wearer can look through the upper part of the lens for distance and use the lower section for reading or close work.

Bifocals are also a well-established option for people who prefer a defined reading area rather than a gradual transition between different viewing distances.

The best choice will depend on your prescription, daily routine and the type of tasks you perform most often.

Bifocals vs Single Vision and Varifocal Lenses

Single vision lenses provide one prescription across the lens, usually for either distance or near vision.

Prescription bifocal glasses provide two separate zones, one for distance and one for close-up vision.

Prescription varifocal glasses work differently. Varifocal lenses provide a gradual transition between distance, intermediate and near vision without a visible dividing line.

Some people prefer bifocals because the two viewing areas are clearly separated, while others prefer varifocals because they provide an additional intermediate range.

The most suitable option depends on your prescription and how you use your glasses during the day.

Who Bifocal Glasses May Suit

Bifocal lenses may suit people who need both distance correction and additional help with close-up vision.

They can be practical for tasks such as:

  • Reading books or documents
  • Looking at labels or small print
  • General distance vision
  • Everyday activities where near and far focus are both required


People who spend a lot of time working at intermediate distances, such as desktop computer use, may want to compare bifocals with other multifocal lens options before ordering.

Your prescription and normal daily routine should guide the decision rather than choosing bifocals based on age or convenience alone.

Choosing Frames for Bifocal Lenses

Frame shape and lens depth can affect how well bifocal lenses work.

The frame needs enough vertical lens space for both the distance and near sections to sit in the correct position. Very shallow frames may not be suitable for some bifocal designs.

Fit is also important. The frame should sit consistently on the face so the two viewing areas remain properly positioned.

When choosing frames, consider:

  • Lens height
  • Frame size
  • Bridge fit
  • Temple length
  • Prescription strength
  • Available lens materials


Stronger prescriptions may also require particular lens materials or thicknesses.

If you are ordering online, it is worth checking that the chosen frame is suitable for bifocal lenses before completing the order.
